Silk Amino Acids

Product Description

Silk Amino Acids are water-soluble peptides derived from hydrolyzed silk fibroin, providing a natural source of amino acids essential for skin and hair health. Produced under controlled conditions, these high-purity peptides ensure consistency, traceability, and high bioavailability in cosmetic formulations.

Rich in serine, glycine, alanine, and other amino acids, Silk Amino Acids help support skin hydration, improve hair strength and elasticity, and enhance overall skin smoothness. Their small molecular weight enables excellent penetration, facilitating moisturizing, conditioning, and repair effects in topical applications.

Silk Amino Acids are increasingly sought after in premium skincare, hair care, and body care products due to their natural origin, multifunctional benefits, and compatibility with diverse cosmetic systems.
