Yeast Amino Acids
What is Yeast Amino Acids?
Yeast Amino Acids consist of a blend of free amino acids obtained through the hydrolysis of yeast proteins, primarily from Saccharomyces cerevisiae. This natural fermentation byproduct yields compounds like glutamic acid, arginine, and lysine. In skincare formulations, they serve as humectants, drawing atmospheric water to the skin's surface and helping maintain hydration levels. They also function as skin conditioning agents by supporting the stratum corneum's natural moisturizing factors, enhancing softness and smoothness without greasiness. Commonly incorporated into moisturizers, serums, masks, and hair care products, they provide lightweight moisture retention ideal for daily routines. Their amino acid profile mimics components found in human skin, promoting biocompatibility and gentle efficacy across various formulations.
