Silk Peptides (Medium Molecular Weight)
Silk Peptides (Medium Molecular Weight) are premium hydrolyzed silk proteins designed to deliver the ideal balance of surface conditioning and deeper moisture support. Unlike ultra-small silk amino acids that penetrate more readily, these medium molecular weight peptides provide both moderate absorption and a luxurious conditioning film on the skin and hair, resulting in exceptional softness, smoothness, and lasting hydration.
Derived from natural silk proteins, these peptides contain a rich blend of amino acids that closely resemble those found naturally in healthy skin and hair. They help improve moisture retention, reduce dryness, enhance elasticity, and leave formulations with a silky, elegant skin feel.
Because they remain partially on the surface while also penetrating the outer layers, Silk Peptides are especially valued in premium hair care and skincare formulations where both immediate conditioning and long-lasting softness are desired.
