AFAs是Amino acid filaggrin based Antioxidants的英文缩写。
Filaggrin是一种存在于人体表皮中的蛋白质。当Filaggrin经代谢分解后，便会形成7个酸性胺基酸，这些胺基酸就是表皮用来保持湿润的重要因子。而AFAs也就是完全比照Filaggrin代谢后所产生的保湿胺基酸研究发展而成，是新一代的医学美容圣品。

AFAs™ Amino Acid Based Skin Care

AFAs 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, the same acidic amino acids 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 are 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 are extremely effective against aging skin and photopigmentation (sun damage).
