Glycolic acid
Glycolic acid is one of the alpha hydroxy acids (AHA) which can be highlighted as one of the most, if not the most, effective kinds of acids from the mentioned group. This is because it is able to get deeper into the skin than other acids because of its smaller molecule size. Glycolic acid is usually naturally sourced from fruits or sugar cane though chemical synthetic products can also be synthesized. Both of them are believed to be equally effective and harmless.
BENIFITS :
Glycolic acid refines the process of exfoliation, as well as minimizes the lines, shrinks the pores, and fades hyperpigmented areas for the purpose of correcting skin luminosity.
SKIN TYPES :
Glycolic acid can improve skin immediately, so you should use it on mature skin, dry skin, oily skin, combination skin, sensitive skin and acne-prone skin.
