Silk Amino Acids (Hydrolyzed Silk)
Highly substantive to skin and hair, Silk Amino Acids PF are highly hygroscopic and have excellent moisture binding ability. Free amino acids are known to penetrate into the upper layers of the skin as well as through the hair cuticle into the hair shaft. This draws moisture into these areas, improving skin and hair hydration. For hair, this results in increased flexibility and manageability, leaving a soft, natural look. Meanwhile, moist, hydrated skin is more supple and has a smoother appearance.
