The Beginner’s Guide To Retinol & Retinoids: How To Prevent Dry, Flaky Side-Effects


In an ever-changing world of skincare advancements related to preventing and reversing the appearance of lines, wrinkles, indented acne scars, large pores, and brown spots, there are TWO facts that have remained constant for the past 30+ years.

FACT #1: Certain types of vitamin A, the ingredient behind retinol and tretinoin (prescription retinoids), will absolutely reverse visible signs of aging. Using a topical product containing these ingredients can increase cell thickness, affect gene expression, thin the stratum corneum, and increase the production of collagen. With continued use, vitamin A slowly improves the skin’s appearance (NCBI Study). It smoothes skin texture by lessening visible wrinkles, lines, acne scar indents, large pores, scarring, and brown spots. Simply put, this ingredient can deliver incredible smoothing and resurfacing results. Thus, it helps the skin mature in a more desirable way.

FACT #2: You must take special care of your skin to manage and prevent potential side effects such as dryness and irritation (especially if you’re using a prescription formula). In the early ’90s when tretinoin first became FDA-approved for treating sun damage, not much was known about controlling its side effects. If misused, the effects were often intolerable. I once had a client who was using prescription Retin-A improperly. She smiled, and in front of my very eyes, areas of her face cracked and started to bleed. I couldn’t believe what I was seeing! These days, the side effects of retinol and retinoids are completely manageable (NCBI Study). All you need to do is take special care of your skin by following my expert tips.

As a product formulator and practicing esthetician with over 30 years of experience, I consider myself well-versed in retinol and retinoids. Fun fact: I personally knew one of the dermatologists who was instrumental in getting this ingredient FDA approved as the first topical preventative aging product (read the full story about when I first met this dermatologist here. It’s a good one.) So without further ado, keep reading to learn my expert tips for getting maximum benefits from a topical vitamin A product, whether it’s a prescription form (retinoid) or in an over-the-counter version (retinol).

The Most Common Types of Vitamin A Ingredients

Retinoid (also known as Tretinoin) is an ingredient derived from vitamin A and only available in prescription formulas. When applied to the skin, it converts directly to retinoic acid. It then binds to cell receptors and activates the cell maturation process in the skin. Brand names include Retin A, Retin-A Micro, and Renova. Other common synthetic retinoids include Tazarotene (brand name Tazorac) and Adapalene (brand name Differin and now sold without a prescription).

Retinol is an ingredient found in non-prescription formulas. When applied (assuming it’s an encapsulated, stable, and well-formulated product), it converts slowly to retinoic acid. It’s time-released, which means it’s delivered into the skin gradually, over a period of hours, instead of all at once like retinoids are. Because of this, retinol users often experience less irritation than retinoid users. Therefore, retinol is ideal for sensitive, reactive skin types, as well as those with less sun damage. Despite being a gentler option, retinol is still extremely effective and can deliver the same results as a prescription with long-term use.

Note: Biochemically, retinoids and retinol perform the same function, which means you’ll get results regardless of which one you choose to use. Results may take a little longer to achieve with retinol-based products, but that’s exactly what is needed for vitamin A newbies and people with sensitive skin types.

Retinyl Palmitate is a storage form of vitamin A. It’s a blend of pure retinol and palmitic acid, and it’s much weaker than retinol. The process of retinyl palmitate converting to retinoic acid is considerably more complex, and the amount that ends up reaching the cellular receptor is very small. It simply cannot compare to the efficacy of pure retinol. When used in a formula, this ingredient can improve the chemical stability of retinol and act as an emollient and antioxidant, but you typically shouldn’t count on it to deliver the same smoothing and brightening results as retinol. Retinyl Acetate, Retinyl Linoleate, and Retinyl Propionate are in this same category.

Retinaldehyde is a stable precursor to retinoic acid. When it’s stable and encapsulated, it can convert slowly within the skin to retinoic acid just like retinol.

It’s important to note that just because a product contains one of the vitamin A ingredients listed above does NOT mean it will necessarily deliver results. You must consider how the formula is made, the percentage used, how it’s delivered into the skin, and how stable it is. You’ll usually have to do a bit of research to find out. If a brand is not readily sharing this information, I consider it a red flag, because it could be representative of the product’s lack of true efficacy. Any good formulator knows this is very important information to share with their customers; they should share their product stats proudly. Read four things to look for when choosing a retinol product.

How to Decide If You Should Use Retinol or Get a Prescription Retinoid From Your Doctor

I start all of my clients on retinol, regardless of how much sun damage their skin has incurred. Here are some guidelines for making this decision for yourself.

 Start using a prescription retinoid if you’re…

  • NOT sensitive at all. If you ARE sensitive, there’s no need to read this section, as a prescription retinoid is not best for you. Most people have a certain degree of skin sensitivity, which is why I suggest using retinol first. If you have the following conditions, though, you can eventually transition to using a prescription retinoid.
  • Someone who’s over the age of 35 with a long history of sun damage. You may feel like your skin shows more visible signs of aging than other people your age.
  • Someone who, regardless of age, has pitted, indented facial scarring from acne in your younger years.
  • Someone who, regardless of age, has melasma from the sun, heat, pregnancy, or hormones. You’ll benefit from something stronger to work deeper and faster. Again though, if you have sensitive skin, it’s best to start with retinol.

Skip a prescription retinoid and use retinol if you’re….

  • Someone who, regardless of age, has thin, dry, and/or sensitive skin. This includes anyone who has rosacea, a history of eczema, or simply an easily irritated skin type. These skin types may never adjust to a prescription retinoid due to the delicate protective barrier that’s easily compromised.
  • Someone under the age of 35 with no major acne issues who’s already using vitamin A to prevent wrinkles, lighten discoloration, reduce pore size, and smooth skin texture. Sticking with retinol and occasional chemical peels is perfect because you’re already getting ahead of the aging process. There’s not as much repair and reversal work to be done in those younger than 35.

When to Start Using Retinol to Prevent Signs of Aging

Assuming that blemishes are not your main concern, I generally recommend starting to use retinol between the ages of 26 and 30. The exact age will depend on your specific skin type, although I do not suggest starting it before 26. There are two reasons for this.

Reason #1: Many people who are younger than 26 are still dealing with breakouts. Despite what you may have heard, retinol or retinoids do NOT help cystic or pustular acne. However, prescription retinoids CAN be effective for managing closed comedones. I discuss this more in detail below.

Reason #2: Vitamin A speeds up the skin’s metabolism, which begins to slow in your early 30s. When you’re younger, your skin is already very metabolically active. Using retinol or retinoids too early might backfire and stir up breakouts, rashes, and more. Basically, it could disrupt the skin’s natural balance.

What to Know Before Using Retinol or a Prescription Retinoid

Avoid using retinol or prescription retinoids while pregnant. Of course, it’s always best to consult with your doctor. In my experience, though, most advise against using vitamin A until after giving birth due to potential risks. I have not personally come across any reported evidence of either topical retinol or retinoids causing harm, but doctors are extra cautious with expecting mothers, and understandably so.

Retinol can be used during the summer months as long as you’re serious about protecting your skin from the sun. Retinol and retinoid products deliver the best results when used two to five nights a week year-round. Using it on and off can slow progress, so it’s important to commit to using it consistently, even during the summer months. As long as you’re someone who practices sun safety and is very conscientious about preventing suntans and sunburns, then you should be just fine.

However, if you are someone who enjoys tanning or someone who hasn’t yet mastered the art of sunburn prevention, I would suggest discontinuing your retinol or retinoid seven days before intense outdoor sun exposure. Start it back up again a week after you’ve been in the sun—assuming you don’t have a sunburn, of course. While this will slow results, it’s super important to prevent skin inflammation and irritation.

You’ll get better and faster results if you use exfoliating acids in your routine, too. When dry, dead cells are regularly removed from the skin’s surface, vitamin A is more easily absorbed. You’ll definitely want to start using an exfoliating acid serum, but more on that later.

Retinol and retinoids do not deliver visible results quickly, so you must be patient. Unlike an exfoliating acid peel that delivers immediate results, vitamin A works incredibly slowly to create change in the skin. I generally tell my clients that they won’t start seeing improved textural changes for two to four months. With continued use, you’ll see more and more positive changes. Do not give up. Stick with it!

You’re not going to get anti-acne benefits with retinol. You might with a prescription retinoid, but only for certain types of breakouts. Yes, prescription retinoids like Retin-A were, in fact, originally developed in the ’70s for treating acne. It wasn’t actually discovered until later that the ingredient also helped with wrinkles. That explains why, for a long time, retinoids had the reputation of being a go-to for acne. The truth is, they’re not for everyone. All skin is not equal and neither is the type of acne that each person experiences. (This explains why you may hear about an acne product working like magic for one person and then making another person’s breakouts worse!)

As for prescription retinoids, the type of acne that they work best for is comedonal acne. This is the type that appears as whiteheads, blackheads, closed comedones, and clogged, non-inflamed bumps. Retinoids restore the organization of cells through cellular turnover. This, in turn, prevents cells from getting trapped and blocked in the pore-lining which in turn, prevents those little non-infected bumps from forming.

Prescription retinoids do not work well for sore, inflamed pustular acne or cysts. In fact, when someone has infected pustular and cystic acne, retinoids may actually make them worse. Acne is an inflammatory disease of the skin. Therefore, it’s not a good idea to stimulate this type of acne with retinoid activity. It’s far better to use products that have more proven acne-improving benefits, such as salicylic acid, tea tree, beta-glucan, niacinamide, manuka, sulfur, lactic acid, and benzoyl peroxide. (On that note: beware of skincare brands that claim their retinol product can treat acne AND wrinkles as a one-stop-shop. This is false and anyone sharing this is simply not informed of how retinol really works. Trust me on this!)

As for retinol and acne, retinol contains a lesser dose of vitamin A, which means it doesn’t work as hard as retinoids do to clear clogged bumps. If breakouts are your main concern, I usually advise my younger, acne-prone clients to focus on clearing blemishes first. Once the skin is clear, they can start using a retinol product to prevent the visible signs of aging. However, there is now a 1% Differin (adapalene) gel retinoid formula available without a prescription for acne. It’s worth adding into your routine to see if it alleviates breakouts.

One more note on retinol and acne—use an exfoliating acid serum that contains salicylic acid on nights you’re not using the retinol to increase vitamin A’s efficacy. I’ll discuss this more at length in a bit. I suggest the Renée Rouleau BHA Clarifying Serum to all of my clients to clear blemishes, as well as the Zit Care Kit for making all kinds of blemishes disappear quickly with minimal scarring.

It’s best to avoid oil-based retinol formulas if you’re prone to clogged pores and blemishes. Some retinol formulas are kept stable in a blend of pure oils. This gives them an emollient, somewhat greasy feel on the skin. While dry skin types can always benefit from oil saturation, oily and breakout-prone skin types should avoid these types of formulas. (The underlying cause of acne is oil—oil breeds bacteria and bacteria lead to blemishes.) Choose your formulas wisely!

If you have a history of eczema, you’ll definitely want to use retinol and not a retinoid. Vitamin A is very active and breaks down the skin’s protective moisture barrier through its aggressive cell turnover process (basically, it causes dryness). That explains why people who have eczema-prone skin find retinoids to cause flare-ups. It’s best to only use retinol.

Even if you’re only applying a prescription retinoid to a specific area of your face, it can treat your face entirely. Some people apply prescription retinoids strategically in an effort to treat a specific area. For example, some people apply it only around their eye area. They think this will help eye-area wrinkles while sparing the rest of their face from dryness. In reality, the ingredient travels underneath the skin. So even if you apply a retinoid to part of your face, it will work everywhere. Subsequently, you can experience dryness everywhere.

A Step-By-Step Guide to Using Retinol

If you’re new to using vitamin A, I suggest starting with a non-prescription version such as retinol. I touched on this above, but to reiterate the reason is that you want to introduce vitamin A to your skin slowly. Most people who start with a prescription (without proper usage instruction) eventually give up because their skin becomes too dry and irritated. If you have a prescription and haven’t been able to use it successfully, consider putting that on hold for now. Start with non-prescription retinol first to introduce it to your skin gradually. Advanced Resurfacing Serum is the retinol product that I personally use. It’s also the one I recommend to my clients. This formula is so effective because it combines stable retinol AND skin-firming peptides that help prevent loss of tone.

Start by using your retinol product two nights on, one night off. Repeat throughout the week. For best results, you must use retinol consistently (and often!). Your skin has other needs, though, so you don’t want to use it every single night. Plus, using it too often could prove too much for your skin, since it’s such a biologically active ingredient.

Following the two nights on, one night off rule will result in four nights a week. If you are over 40 with a history of sun damage and your skin isn’t overly sensitive, you can use it four to five nights a week. However, no one should use it for more than five nights a week. This can eventually result in increased sensitivity and a waxy and unnatural appearance.

On the other hand, if you’re under 40 and your skin is fairly sensitive, you might start by using it only twice a week. Then after two months, you can work up to using it three nights a week. Eventually, work up to four nights a week. When in doubt, start slow and increase as you go along. If you’re experiencing dryness or irritation, you’re either using too much or using it too often. This is a sure sign that you should cut back. Remember: using retinol or retinoids successfully is a marathon, not a sprint.

Avoid applying moisturizer immediately after applying retinol. Using a cream or lotion right after applying retinol may dilute it slightly. It’s best to let it absorb for 20 minutes. Or, you can use a retinol serum that has a lotion-like texture. This can offer hydrating and protective benefits, thus skipping the need for moisturizer altogether.

To maximize results and minimize potential side effects (a win-win), use an exfoliating acid serum on opposite nights. This is really important. Retinol works to encourage dull, sun-damaged skin cells to rise to the surface for easy removal. Using a gentle, alcohol-free exfoliating acid serum once or twice a week (such as one with glycolic, lactic, salicylic, or mandelic acid) will accelerate these cells’ removal. Vitamin A can then absorb deeper into the skin to perform its best. Using both in your routine will reveal a smoother, more even-toned texture.

A lot of people use exfoliating toners that contain acids. They often ask me where they should plug that into a retinol or retinoid routine. I never suggest that my clients exfoliate every day, so I don’t recommend using an acid-based toner every morning and night. This is regardless of whether or not you’re using any vitamin A products. If you want to use an exfoliating toner, I would suggest using it on the nights that you use the retinol or retinoid. It can act as a pre-treatment/primer to allow the vitamin A ingredient to absorb deeper into the skin.

Did you know that acids actually help correct dryness? When people experience surface dryness (due to age, drying products, airplane travel, etc), their first instinct is to apply a facial oil or heavy moisturizer. This is helpful for pushing moisture into the top layers of the skin, but the dry, expired cells want to (and desperately need to) come off. Over-moisturizing may interfere with and slow down cell turnover. Regularly using exfoliating acids is like saying “out with the old and in with the new” to your skin. This is why top dermatologists and skincare professionals recommend acids so widely.

Once a week, skip the exfoliating acid or retinol and use a hydrating serum containing antioxidants, epidermal growth factors, or peptides. Your skin requires a variety of ingredients to age healthily. Therefore, you don’t want to constantly stay in exfoliation/cell turnover mode by only using acids and retinol. It’s just like your exercise routine. When working out, it’s best to alternate between various types of exercise, so you’re getting a little bit of everything. Your skin appreciates the same variety. The Renée Rouleau Firm + Repair Overnight Serum is the one I suggest to a lot of my clients.

To boost results, get a professional chemical peel or give yourself one at home. Once you’ve been on your new retinol routine for two months, it’s good to kick it up a notch. Try introducing your skin to a chemical peel—especially if you’re someone who has large pores, wrinkles, and discoloration from sun damage. A peel is essentially a stronger version of retinol. It’s intensifying your skin’s collagen-boosting activity to encourage faster smoothing results. Synergistically, they both support one another in the quest for smoother, more even-toned skin.

There are many types of peels, so you’ll want to consult with a trusted skincare professional to find out which type and what frequency is best for your skin. I generally recommend that clients get light to medium chemical peels (ones that make your skin shed for a few days after) six to eight times a year. You can get lighter peels every other month.

The Renée Rouleau Triple Berry Smoothing Peel is great to use three to four times a month. There are no harsh side effects, only beautiful results to increase the skin-smoothing benefits of retinol. You can also give yourself a DIY chemical peel at home if you happen to have a tube of a prescription retinoid lying around. Learn how, here.

After six months, if you think you want to start using a prescription retinoid to increase your results, introduce it into your routine slowly. Of course, you’ll have to consult with a doctor about this. There are so many different kinds, but your doctor can suggest what’s best for you and your specific skin goals. You should start with the lowest strength.

How to Introduce a Prescription Retinoid Into Your Routine

Weeks one through four, substitute your retinol serum with a prescription retinoid ONE night a week. After cleansing, immediately apply an alcohol-free toner. Leave it damp, then apply a thin layer of a lightweight moisturizer to the skin before applying your retinoid. The moisturizer cannot be heavy or greasy at all. Wait for five minutes and apply a pea-sized amount of the prescription to the entire face. (I recommend treating the neck and chest with retinoids, too. Use an extra pea-sized amount for this area as well.) Let dry for 20 minutes and follow with another application of moisturizer. This time, you can use your normal moisturizer. Ideally, use one that keeps the skin’s moisture barrier intact and sensitivity to a minimum. The Renée Rouleau Phytolipid Comfort Creme is a great option for new retinoid users.

Note: There has been much discussion in years past about whether or not using a moisturizer underneath vitamin A affects its performance. Most believe that it does not interfere with penetration. Instead, the right moisturizer can keep the moisture barrier beautifully intact to prevent dryness. This is truly the secret to making a prescription tolerable. I always recommend the Renée Rouleau Sheer Moisture Lotion to my clients due to its light texture and stable antioxidants. Retinoids can cause “micro wounding” in the skin, and antioxidants help stop the resulting inflammatory response. This makes Sheer Moisture a perfect companion to prescription formulas.

Weeks four through ten, repeat the above process but now substitute your retinol serum with a prescription retinoid TWO nights a week. Think of your prescription retinoid as a workout for your skin. You don’t want to lift the heaviest weights on day one. Instead, you want to take it slow and gradually build up to it over time.

Weeks 10 and beyond, repeat the above process but now substitute your retinol serum with a prescription retinoid THREE nights a week. For most people, I suggest sticking with this routine for the long run. You’ll alternate nights between your original retinol serum (eventually you can drop this), a retinoid, an exfoliating acid serum, and a hydrating serum. You’ll use your prescription retinoid three nights a week while giving your skin an amazing variety of other active ingredients. They’ll all work synergistically to improve the look of your brown spots, wrinkles, and large pores.

If you have very sun-damaged or acne-damaged skin, you may want to increase the prescription retinoid to four nights a week after six months. Also, consider upgrading to a new one with a stronger percentage. I do, however, discourage people from getting too excited and using it too frequently. Over time, this can cause the skin to appear tight, shiny, and waxy, almost like a plastic Barbie doll. I can spot someone a mile away who is overusing prescription retinoids, and it’s not a great look. It just doesn’t look natural.

So there you have it. I’ve covered almost everything you need to know about what I believe is the closest thing we have to a fountain of youth—retinol and retinoids. I’ve seen the results it can provide on so many of my clients’ faces in the past 30 years of my career. While I’m super proud of the retinol formula I created, there are other great ones out there, too. You just have to do your due diligence since it’s a tricky ingredient with which to work, and not all formulators know how to make the best products.

I’ll leave you with one last thought. As I mentioned previously, using a retinol or retinoid is a marathon, not a sprint. It can take a while to see results, meaning you won’t get immediate gratification. To truly reap its benefits, without incurring dryness or irritation, deliver a slow drip of it to the skin. I recommend using it regularly for the rest of your life…or until a better anti-aging product takes its place! And if that’s the case, I’ll be sure to let you know. For now, head on down Retinol Road.

Next, find out whether or not retinol and prescription retinoids make the skin thinner.

  2. Hi! I just purchased your Resurfacing serum. I also purchased your overnight serum firm and repair. Can I use these two together on the same night or do I switch back-and-forth? By the way I am obsessed with your luxe meant cleansing gel! It is the best facial cleanser I have ever used:) thanks so much

    Posted By: Claudine  | 

    • I am so glad the products are giving you the results you have wanted. Ideally, you will use the Advanced Resurfacing Serum two nights in a row and the Firm + Repair one night. Continue alternating serums. Be sure to use your Overnight Eye Serum on a night you use Firm + Repair.

  3. How about the morning routine? Should I keep using my vitamin c or other antioxidants before my spf, while on Prescription Retinoid use? Thank you in advance 🙂

  4. Hi Renee,

    I’ve been looking at your products and reading your blogs for some time now. A few years ago, I purchased your Anti Cyst Treatment summer of 2018 to use on the cyst I had that wouldn’t go away. I finally had to have it injected with a steroid. That cyst seemed to be the start of my skin issues since my early 30’s.
    I am 49, soon to be 50 years old. I have fair skin that can be sensitive. I broke out with cystic acne (just one at a time, but very large, red and painful) in my early 20’s and early 30’s. In my mid 30’s I started using Proactive. I used their original products for awhile and then switched to using their Gentle Formula Cleanser (Salicylic Acid) and Toner (Glycolic Acid), Repairing Treatment (Benzoyl Peroxide) and either their Green Tea moisturizer or Moisture Repair. This system, as crazy as it sounds worked for years. A little over a year ago, they changed the ingredients of the Gentle Formula cleanser (horrible consistency and smell), so I had to start looking for a new one. I stumbled across Dermalogica and started using some of their products last spring. The esthetician I saw said my skin was very sensitized and dehydrated. After trying several of their products, I am currently using their Ultra Calming Cleanser morning and night, Daily Microfoliant mixed in with the cleanser only at night and Ultra Calming Mist in the morning. I am also using Proactive’s Gentle Formula Day lotion/moisturizer (2% Salicylic Acid) after toning in the am and their Gentle Formula Night Cream (1% Salicylic Acid/Retinol/Retinol Palmytate). I use Dermalogica’s Prisma Protect sunscreen. I am now also on Spironolactone for monthly cysts. I have been on that since last September. That really seems to be helping and I haven’t had any cysts since October. However, I still have some tiny under the skin bumps on the right side of my chin that nothing seems to make go away. They’re not that noticeable or cause any pain… There just there. I also have some on my left cheek and temples. I am a teacher, so I wear makeup during the school year, but not in the summer. I prefer not wearing makeup because it just feels like too much on my skin. My skin doesn’t seem to “absorb” very well. For the most part, lotions and serums feel as if they just sit on the surface of my skin and have a “tacky” feel. I know… I am truly a hot mess and most likely every esthetician’s night mare!
    The past few weeks, I have been looking at Skin Types 4, 5 and 6 as it seems I’m a bit of all 3. My face tends to get red/flushed at certain times of the month. Now that I’m on Spironolactone, the cysts seem to be under control, but I want to make sure I’m doing what’s right for my skin.
    I feel that the Proactive products with Glycolic acid, Salicylic acid and retinol (the little that is in the Night Cream) have been helping, but have been looking at your serums as an alternative. Currently, I have the Advanced Resurfacing Serum, Pore +Wrinkle serum, Firm + Repair serum, Weightless Protection and Hydraboost Rescue Cream in my cart. While I’m not opposed to spending money for good products, I’m just not sure I can spend that much at this time. I just want the right products for my skin. I’m a bit nervous, since I’m not able to see any reviews and you have a no refund policy.

    With all this being said, I could really use some advice! I value your opinion and look forward to hearing from you!

    • Hello! I’m sorry to hear you’re experiencing some dehydration and continued breakouts. You sound like a perfect candidate for a virtual consultation! Virtual consultations connect you with a listened esthetician to talk about your skin’s concerns and needs. They will assign you with a skin type number and create a custom routine for you. Normally consultations are $100, however that fee is waived when you purchase $100 worth of product during your appointment. You can learn more and book here:

  5. I’m so depressed because I think I forever damaged my face with retinol. After using the Sunday Riley A+, I now have visible pores all over my face and when I smile the pores connect to form lines that make me look extremely old. I’ve read countless blogs where this has happened to others and no one has been able to cure this phenomenon and I’ve had this condition for 8 months now. Before this I had dry normal and Non visible pores prior to using retinol and zero lines. Have you heard about this condition and do you know how to reverse the damage? Any advice is greatly appreciated as many of us are suffering from the effects of retinol. Thank you.

  6. Can i used 4 nights of retin A and 3 nights of retinol im 43

    Posted By: Marites  | 

    • I wouldn’t recommend this since that’s 7 days of retinol/retinoid use. I believe it’s best to rotate in other ingredients such as exfoliating acids and hydrating, firming ingredients. I would suggest using Retin A 4 nights and then using these other ingredients the remaining 3 days.

      Posted By: Renée Rouleau  | 

  7. Hello Renée,
    I’ve just read above that you recommend using exfoliating acids on the same nights as Retinol, but I’ve also read on another post of yours that you should alternate (2 nights on with Retinol and 1 night off for the exfoliating acid, etc.) these products. Which do you recommend?
    Thank You!

    Posted By: Kieran Hathway  | 

    • Hi! I recommend alternating the two. Ideally, I suggest that my clients work up to three nights retinol and followed by three nights of an exfoliating acid, then a day with just a moisturizing serum before starting the cycle again. Hope this helps!

      Posted By: Renée Rouleau  | 

      • Hello again!
        As I’m in my early twenties, is it best to have three nights of retinol, three nights of exfoliating acid, etc. or should I limit the use of retinol?

        Posted By: Kieran Hathway  | 

      • Hi! I recommend two nights of retinol followed by one night of exfoliation, repeat, then just hydration the seventh day.

        Posted By: Renée Rouleau  | 

  8. Can you recommend any retinol product that have pimple break out on my face?

    Posted By: Best Otc Retinol  | 

    • If you’re looking for a retinol product to help with breakouts, I recommend seeing a dermatologist.

      Posted By: Renée Rouleau  | 

  9. What do you recommend for people who are allergic to RetinA? When I try to use it, I literally want to claw my face and neck off!

    Posted By: Mandi Wells  | 

    • Hi! Some people are just too sensitive for prescription retinoids. I recommend sticking with a milder, over-the-counter retinol and slowly building up to using it a few times a week.

      Posted By: Renée Rouleau  | 

  10. Great information thank you! How soon after a light to medium peel would you reccomend resuming retin-a?

    Posted By: Jennifer  | 

    • Hi Jennifer, I would advise you to speak with whoever performed the peel since they will be familiar with your skin and can provide you with the best post-care instructions for your specific treatment. In general, wait until your skin is fully healed and no longer shows signs of peeling or flaking to slowly re-introduce retin-a into your routine. Listen to your skin!
