Updated 3/29/17. After a long winter with many cold, dreary, overcast days, the skin can look and feel dull, tired and lackluster. The best way to start brightening it back up, while keeping it protected from increasingly more daylight, is to use vitamin C on the skin, in the form of a serum underneath your sunscreen moisturizer. However, while it’s such a tried-and-true ingredient and long been endorsed by dermatologists and skincare experts, there is still much discussion about which type of topical vitamin C is the most effective for reducing inflammation and free radical activity while brightening discoloration and preventing the visible signs of aging. Here’s what you need to know when choosing a vitamin C formula to use on your own skin.
There are two general categories of vitamin C serums.
Stable forms of topical vitamin C: This means it doesn’t discolor and won’t break down and lose its effectiveness over time. It’s good to the last drop.
These ingredients are known as:
Magnesium Ascorbyl Phosphate (also a proven skin lightener to fade brown spots and discoloration from age, sun, breakouts, and hormones)
Ascorbyl Methylsilanol Pectinate
Sodium Ascorbyl Phosphate
Unstable forms of topical vitamin C: This means it will turn dark yellow or golden brown over time as the air oxidizes the formula, resulting in less benefit to the skin. This unstable type, due to its acidic nature, can cause stinging when applied to the skin resulting in irritation, especially for sensitive skin types and retinol, prescription retinoid users and those who exfoliate their skin regularly.
These ingredients are known as:
To further understand the oxidation process and unstable vitamin C, think about If you take a bite of an apple and set it down on a table. What will happen? it will start to discolor and turn brown within 20 minutes. This happens because the air is oxidizing the apple. (Check out this cool experiment I did with an apple and a vitamin C serum.) When you’re using an unstable form of vitamin C on your face, it runs the risk of oxidizing quickly on the face and may not give you all the amazing benefits as it’s starting to lose its potency.
When it comes to choosing a vitamin C antioxidant formula, do so carefully. You want to get the best results for your skin and get your money’s worth. I highly recommend using a stable, no-sting formula. When used daily, your skin will look brighter, fresher, and brown discoloration from sun, hormones, aging, and blemishes will fade. The one that I recommend to all of my clients is Vitamin C&E Treatment since it uses three forms of stable vitamin C (ascorbyl palmitate, magnesium ascorbyl phospate and ascorbyl methylsilanol pectinate) along with vitamin E. Upon application, it converts to ascorbyl acid once inside the skin; it stays stable and is time-released so it works for up to 8 hours. Additionally, it acts as a natural skin lightener to fade stubborn brown spots and post-breakout marks to reveal a brighter, fresher-looking complexion. Vitamin C&E Treatment can be safely used for all skin types—especially sensitive, easily-irritated skin. Bonus! Durham, N.C.-based Duke University Medical Center researchers have determined that using a lotion or serum with vitamins C and E under sunscreen actually provides four times the protection of sunscreen alone so with spring and summer, this is especially effective.
