In the beginning came AHAs (alpha hydroxy acids). These glycolic, lactic or fruit acids are used as peels to exfoliate the skin. There was some pain (burning sensation, maybe the formation of scabs) and only some gain. Results were more on the subtle side. Then came along AFAs, amino fruit acids. No pain and more gain. Worth investigating.
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.
