Amino acid based chemistries in skin cleansing In the last 20 years, therapeutically orientated cosmetics have grown enormously. Products that claim to reduce the visible signs of skin ageing include those containing free amino acids such as alanine, arginine, aspartic acid, glutamic acid, tryptophan, threonine and serine. Contrary to popular belief, these chemistries also play an important role in skin cleansing preparations.
