Typical ConcentrationConcentrations vary widely (10-80% extract). Products like COSRX Propolis line use high concentrations. Apply after cleansing. Can be used morning and night. Patch test first — bee product allergies are possible.Concentrations: 70-97% snail secretion filtrate in dedicated products. Apply after cleansing and toning, before heavier products. Safe for morning and night use. Results improve with consistent daily use over 4-8 weeks.
ApplicationTopical (serum, essence, ampoule, cream). Available in many K-beauty products.Topical (essence, serum, cream, mask). Apply to clean, damp skin. Pat gently to absorb.

Mechanism of Action

Propolis

CAPE (caffeic acid phenethyl ester) inhibits NF-kappa B nuclear translocation by preventing I-kappa B alpha degradation and blocking p65/p50 nuclear import — suppresses TNF-alpha, IL-1beta, IL-6, COX-2 transcription. Flavonoids (chrysin, pinocembrin, galangin) provide antioxidant protection through free radical scavenging and metal chelation. Bacteriostatic and bactericidal against Cutibacterium acnes and Staphylococcus aureus via cell wall disruption and protein synthesis inhibition. Promotes wound healing: stimulates fibroblast collagen I/III synthesis, keratinocyte migration (integrins, matrix metalloproteinases), angiogenesis. Inhibits hyaluronidase, preserving skin hyaluronic acid. Effective for acne (reduces inflammation, bacterial load) and sensitive skin (calming barrier disruption).

Snail Mucin

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.
