Amino acids do not seem to get much attention on this site. Are the chemist that are formulating really top end products using these, or are they primarily relegated to the claim catalog?
I am asking in a very broad scope....any benefits for skin or formulations, ie: NAC as an antioxidant, or Proline as a possible building block? Are there any good papers that cover the possible benefits of any of the amino acids...essential or non as applied to skincare? Not that interested in raising pH with Arginine, but concrete steps towards better skin health.
I enjoy reading a good paper...so links are appreciated.
