Fundamental constituents of all proteins found in the body, such as: alanine, arginine, asparagine, aspartic acid, cysteine, cystine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine. Some of these amino acids can be synthesized by the body; others (known as essential amino acids) must be obtained from protein in the diet.
In skincare products, amino acids act primarily as water-binding agents, but some have antioxidant properties and wound-healing abilities as well. However, amino acids cannot affect, change, or repair wrinkles.
