Collagen-Derived Amino Acids (Collagen Amino Acids)

Collagen Amino Acids are a blend of low–molecular weight amino acids obtained from hydrolyzed collagen, valued in cosmetic formulations for their moisturizing, smoothing, and skin- and hair-conditioning benefits. Acting as water-binding humectants, they help improve skin softness and suppleness, support a more comfortable feel, and enhance the appearance of smoothness by reducing the look of surface dryness. In hair care, Collagen Amino Acids contribute to improved manageability and shine by forming a lightweight conditioning film that helps reduce friction and supports a softer, healthier-looking fiber. Well-suited to plumping, “bounce,” and sensorial hydration concepts, they are commonly incorporated into serums, moisturizers, masks, cleansers, shampoos, conditioners, and leave-in treatments, typically at low to moderate use levels and formulated for broad compatibility across skin and scalp types.
