If you're looking for a skincare ingredient that can brighten your skin, boost collagen synthesis, calm down inflammation, and reduce the appearance of pigmentation, look no further than Vitamin C. A Vitamin C-infused serum, for example, will do wonders for your skin as an added step to your routine. In fact, dermatologist Dr. Joshua Zeichner tells Vogue that Vitamin C is the most potent topical antioxidant, and it helps neutralize free radical damage and protect the skin against UV light exposure and other environmental pollutants.
Ingredients You Shouldn't Mix with Vitamin C
As beneficial Vitamin C is for the skin, the struggle in using it lies in the fact that it shouldn't be combined with several skincare ingredients. One way around it is to opt to use it alone in the morning, and then use the other ingredients before bed—that way, both can work to their full potential without clashing. Below, we list the four ingredients that won't go well when mixed with Vitamin C and why:
Alpha-hydroxy acids like Glycolic Acid and Lactic Acid can alter the pH formula of Vitamin C. This can also degrade the antioxidant properties of Vitamin C and might cause skin irritation.
Salicylic acid, a form of beta-hydroxy acid, can also alter the pH formula of Vitamin C like AHAs. Thus, this is not recommendable to be mixed with Vitamin C as well.
3. Retinol (Vitamin A derivative)
Retinol and Vitamin C are both effective in combatting the signs of premature aging. However, using them together can be very irritating to the skin as this could exacerbate skin sensitivity and worsen signs of aging.
4. Benzoyl Peroxide
It is not recommended to use Benzoyl and Vitamin C together because they can offset each other’s effects and benzoyl peroxide can oxidize Vitamin C.
How to Apply Your Vitamin C Serum
To fully maximize the benefits of Vitamin C, it has to be applied on the skin after proper cleansing and exfoliating for maximum penetration. In addition, it can be incorporated in your morning skincare routine by applying a few drops on a freshly-cleansed and toned face before sealing it with moisturizer and sunscreen to protect skin from harmful free radicals.
How to Store Your Vitamin C Serum
Vitamin C is an unstable ingredient which easily breaks down and oxidizes when exposed to harsh environments. Thus, Vitamin C-infused skincare products should be away from the presence of harsh air and light and just kept in room or cool temperature. Usually, oxidized Vitamin C serums show a difference in color. A fresh one is usually opaque or white, when oxidized, it becomes yellowish. You can also keep it in a beauty fridge to prolong its shelf life!
