It brightens your skin and protects it from external damage, but what is the right percentage of vitamin C?
Vitamin C is a powerful antioxidant, anti-inflammatory, it brightens the skin, supports collagen production and protects against UV damage. But there are several different concentrations of vitamin C in serums in the market, so, how high is high?
Experts recommend anything from 10% onwards, although it might depend on your skin type. While sensitive skin normally requires a 5% formula, average skin type would need up to 15% and 20% for oily skin type –there is no need to use a higher percentage as there are no additional benefits to it.
Always make sure you don’t expose it to light as it can oxidize vitamin C, that is why you should choose an opaque bottle. Also, look for the vitamin C that is in the form of I-ascorbic acid as it is the most active one. Don’t be surprised if you get a stinging feeling, it is what happens when the skin adjusts to the pH of the product and in a few minutes, it will stop. If it lasts for more than 5 minutes or you observe redness or itching, probably the product is too high for your skin.
Bonus tip: Go for a Vitamin C serum that has been paired with antioxidant ferulic acid –it will reduce fine lines– and vitamin E to boost your skin’s barrier function.
