Vitamin C or ascorbic acid ((l-ascorbic acid) (not to be confused with citric acid) is used in cosmetics to protect skin cells from the penetration of toxins from the environment, from cell destruction by free radicals, for skin tone smoothing (removal of pigmentation), for strengthening of vessels (couperose problems) and in anti-aging cosmetics.
When you are about to start using a product with Vit C, look for low concentrations (starting from 1%), but note the maximum effectiveness you will get from the concentration of vitamin starting from 10% through 20%.
Please be careful with acid pH balance which should be from 2.8 to 3.4 – this range is considered optimal not to irritate the skin. Products with pH balance lower than 2.8 may irritate the skin, while those with pH higher than 3.4 are not effective.
Vit C works best together with vitamin E, ferulic acid, tyrosine and zinc.
