How To Avoid A Negative Reaction To New Skin Care Products

Especially for those with sensitive skin and those prone to blemishes and breakouts, incorporating new skin care products into your routine can be a scary undertaking – simply because you just don’t know how your skin will respond, even if you’ve chosen products for your skin type. Here are some things you need to know when trying out new skin care products.

1) Don’t go it alone. It’s really important that you consult a skin care professional, and not self-diagnose your own skin. I can’t tell you how many times clients have thought their skin was a certain skin type, when in fact it was something different. (For example, so many people with oily skin always use products for controlling their oil, when in fact they really need to focus on putting water-based hydration into the skin.) Find a trusted professional with years of skin care experience and allow them to help you with your product selection. Be sure to communicate thoroughly what your concerns are.

2) Perform a patch test. If you have extremely sensitive and allergic skin, it’s always recommended to do a patch test for compatibility prior to using any new products. When you’re trying a new line you’re excited to dive right in and use everything, but if you have a negative reaction to something you’ll never know what it was. You might make some of your own assumptions, but it’s really hard for you to determine for sure.

How to test for possible allergic reactions: The side of the neck is a good starting point for true compatibility because it’s thinner and generally more reactive. The idea is that if it can be tolerated on your neck, then you can feel confident that it will be okay on the face. Also, should you encounter a negative reaction such as an itchy, red rash, you might want it to appear on the neck rather than on your face.

Note: The product category that allergic skins are most reactive to are products that you would leave on the skin (moisturizer, serum, toner, eye cream) as opposed to a cleanser that you apply and rinse right off. Also, if you are doing a patch test with a product that contains Glycolic Acid, Lactic Acid, Salicylic Acid or other AHA’s, it is normal that the skin may be slightly pink but this should usually subside within 10-15 minutes, especially if moisturizer is applied on the skin over it.

What to do if you have an allergic reaction? If you ever use a product and break out in a rash, you can apply either Milk of Magnesia or cold plain yogurt to the affected area. Leave on 15 minutes, rinse and repeat every three hours.

What’s the #1 ingredient most likely to cause an allergic reaction? Synthetic fragrance which will be listed as “fragrance”, “parfum” or “perfume” on the back of the packaging. At Renée Rouleau, we don’t use any artificial perfumes in any of our products.

How to test for possible blemishes or clogged pores: The cheek (close to the nose) or chin area is a good place to test if you’re prone to breakouts. There are a higher amount of oil glands and pores in these areas so the product can penetrate deep into the pore lining. If a product is going to cause breakouts, it’s most often not going to happen after just one use, so you may want to consider testing a small area for 7-10 days if you really want to be cautious.

If all tests well, you can proceed to using your products on the entire face.

3) Introduce your products slowly. When using new products, even if you have patch-tested and no negative reaction has occurred, I still believe that it is best to only introduce one new product every five days. This way, if a negative reaction should occur, you are able to pinpoint which product it may be, and then you will have this helpful knowledge for future skin care purchases.

Bottom line: for best results, when introducing new skin care products, it is best to take it slow. Be sure to contact us if you need any assistance!
