Centella AsiaticavsSnail Mucin

The four key triterpenoid saponins—madecassoside, asiaticoside, madecassic acid, and asiatic acid—exert distinct but complementary mechanisms. Madecassoside and asiaticoside are anti-inflammatory: they inhibit NF-κB nuclear translocation and IκB kinase activity, reducing TNF-α, IL-6, and IL-1β production in keratinocytes and dermal cells. Madecassic acid and asiatic acid (the aglycone forms) stimulate type I and III collagen synthesis in fibroblasts by upregulating collagen gene expression and procollagen production. All four compounds promote wound healing by stimulating angiogenesis via VEGF (vascular endothelial growth factor) upregulation, fibroblast proliferation and migration, and extracellular matrix remodeling. Centella extracts also increase superoxide dismutase (SOD) and catalase activity in skin cells, enhancing endogenous antioxidant defense. The triterpenes may modulate TGF-β and Smad signaling. TECA (Titrated Extract of Centella Asiatica) standardizes these actives for consistent clinical efficacy.

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.
