Snail MucinvsSqualane

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.

Squalane is the fully hydrogenated form of squalene—a C30 isoprenoid hydrocarbon. As a saturated branched-chain hydrocarbon, squalane forms a non-occlusive emollient film that fills intercellular lipid spaces and reduces transepidermal water loss (TEWL) by approximately 20-30%. Squalene comprises ~12% of human sebum (synthesized via mevalonate pathway); squalane's structural similarity confers high biocompatibility and minimal comedogenic potential. Hydrogenation of squalene's six double bonds eliminates oxidative susceptibility—squalene peroxidizes with UV exposure while squalane remains stable. Squalane penetrates the stratum corneum and may support barrier lipid organization. Plant-derived squalane (sugarcane, olive) is structurally identical.
