AFA(acidified amino acid)

AFA (Amino Acid Skin Care) products are based on the amino acids that are recognized as part of the Natural Moisture Factors (NMF) of human skin.

AFAs are a rapidly effective antioxidant created by the dissolution and acidification of natural acidic amino acids, that are found in the skin. The term AFA stands for Amino Acid Filaggrin-Based Antioxidants. Filaggrin is a protein that occurs in the upper layer of the skin, the epidermis. Filaggrin is metabolized in the epidermis into several acidic amino acids and these amino acids are the primary agents responsible for the skin’s ability to retain moisture. They're also the same amino acids used to produce AFAs.

AFAs are potent, stable antioxidants and powerful exfoliants with little to no irritation unlike AHAs, glycolic acids, or other alpha hydroxy acids. They supplement the amino acids so vital to helping the skin to retain more moisture. They're extremely effective against aging skin and photopigmentation (sun damage).
