Luxury Silk Touch for Hair, Skin and Color Cosmetics
Silk amino acids are the smallest building blocks of silk protein, separated so they dissolve completely in water. That small size is exactly why formulators love them: they help hold moisture at the surface of skin and hair and leave a silky slip without any heaviness, even in light serums and mists.
Why Formulators Choose Silk Amino Acids Liquid
Few ingredients carry a stronger luxury cue on an INCI list than silk. Silk Amino Acids Liquid BLP lets you add that story to almost any product, from shampoo to foundation, at a cost per batch that stays reasonable because a little goes a long way.
