Reduces Hyperpigmentation
Vitamin C is an antioxidant that, among its many uses, can be applied topically to the skin as a serum to help reduce hyperpigmentation. In addition, studies have shown that vitamin C can help protect the skin from sun damage and reduce the appearance of dark spots. It can also increase collagen production and stimulate ceramide production, which are important factors in helping the skin maintain moisture and elasticity.
When used topically as a serum, vitamin C will be absorbed into the skin, although it’s unclear how much is absorbed into the bloodstream. When looking for a serum containing vitamin C, it’s important to note that most serums don’t list a concentration of vitamin C on the label. Instead, you should look for other indicators, such as the word “ascorbic” or “L-ascorbic acid,” which indicates that there is some amount of vitamin C in it (although it may not be enough to do anything). Also, serums with a concentration above 10% are considered safe by most dermatologists and experts in skincare.
