Gluconolactone (PHA)vsSnail Mucin

Gluconolactone hydrolyzes desmosomal proteins and glycosaminoglycan bonds between corneocytes in stratum corneum, promoting desquamation. Large molecular size (178 Da vs glycolic acid 76 Da) means slow, even penetration through lipid bilayer — no irritation-causing 'hot spots' of concentrated acid. Gentle, sustained exfoliation. Six hydroxyl groups per molecule make it a potent humectant, forming hydrogen bonds with water and drawing moisture into stratum corneum. Chelates iron and copper ions, reducing metal-catalyzed free radical formation. Has antioxidant properties. Unlike AHAs, does not increase UV sensitivity. Lactone ring hydrolyzes to gluconic acid at skin pH. Ideal for sensitive skin, rosacea, those intolerant of glycolic or salicylic acid.

Snail secretion filtrate (Cryptomphalus aspersa) is a complex mixture of bioactive compounds. Hyaluronic acid (multiple molecular weights) provides humectant hydration by binding water in the stratum corneum and dermis. Glycoproteins and proteoglycans contain growth factors and enzymes that accelerate wound healing, promote fibroblast and keratinocyte proliferation, and support extracellular matrix remodeling. Copper peptides (e.g., GHK-Cu) naturally present stimulate collagen and elastin production via upregulation of collagen genes and inhibition of MMPs; they also have antioxidant and anti-inflammatory activity. Antimicrobial peptides (e.g., defensin-like molecules) provide mild protection against bacteria. Allantoin soothes, promotes cell turnover, and supports barrier repair. The secretion also contains glycolic acid (mild exfoliation), vitamins, and trace minerals. The combination replicates functions of multiple skincare ingredients—hydration, wound healing, antioxidant defense, and barrier support—in a single biocompatible secretion. Filtrate processing removes snail cells while preserving bioactive compounds.
