What Is It: AFAs (amino fruit acids)
The urge to find out more about AFAs came when I picked up some Fix My Skin Gel with AFAs. This is a nice gel with mercifully few ingredients. I'll come back to it. First what are AFAs? The acronym stands for Amino Acid Filaggrin. Filaggrin is a protein in the upper layer of skin, composed of acidic amino acids and responsible for retaining moisture.
The invention for mimicking this was patented by Dr Marvin E Klein and he has his own skin care range based on AFAs called Excel Cosmeceuticals. Because AFAs are very small molecules and have a low pH, they are supposed to be very effective exfoliants. Plus they have three positively charged hydrogen ions (AHAs have only one) and this makes them potent anti-oxidants.
There is little to no irritation with AFAs - although the science
seems a little hazy as to why. In any event, AFAs do not produce a
visible peeling in the way that AHAs do. They are particularly good at
dealing with photopigmentation - age spots - on areas where the skin is
thin, such as the hands.
Anyway, back to FixMySkin Gel.
I am trying out the mild version. The initial feeling is moist and silky. I think this may have to do with the thickening agent in the gel that is based on plant gum. There is vitamin c and Dead Sea minerals. I doubt whether it will pack the punch of Doc Marvin's real McCoy, but it will be interesting to see how it goes.
