Hexapeptide masks are Hydrolyzed Marine Collagen Peptide, Sodium Alginate Based and made with 100% pure ingredients. Hydrolyzed Marine Collagen Peptide is more than just protein powder. Hydrolyzed Collagen is broken down into smaller molecules so it’s easier to absorb into the skin. Alginate is a natural sugar that is extracted from the cell wall of brown Algae in cold water areas. Alginate is extremely soothing, calming and hydrating, and has the exceptional quality of “holding on to” or “carrying” other active ingredients into the skin. The Hexapeptide Jelly Mask Series is filled with Hyaluronic Acid, Aloe Barbandensis Leaf Extract, Trehalose, Vit B3 and E, Alginine, Senine, Pentapeptide-5, Growth Modulating Peptide, Hexapeptide-3 and Recombinant EGF to create the ultimate Hydrating Mask. All the masks are GLUTEN FREE.
