How often should you apply Vitamin C on your face? 5 best serums to add in your skincare collection 

Vitamin C has become a mainstay in most skincare regimes owing to its ability to brighten the complex, boost collagen production, and enhance circulation. Dull skin? Dark spots? Hyperpigmentation? A Vitamin C serum addresses it all.

One commonly asked question regarding these serums is how often they can be applied on the face. Dermo-cosmetic expert, Ana Santamarina, explains that the vitamin in its pure form has been observed to create a reservoir in the skin under certain conditions, and it can accumulate in the skin for three-four days, hence creating the possibility of not using it daily.

One should look for a serum formulation that effectively delivers antioxidant protection. According to experts, the ideal formulation should be a serum with 10-15% ascorbic acid at a pH value of 3.5 or lower.
