Product Overview
Our Silk Cut Cocoon is premium skincare ingredient extracted from 100% pure Huakang No.3 spring mulberry silkworm cocoons (Bombyx mori). The whole cocoon undergoes exclusive physical cutting and sterile purification procedures without bleaching, chemical solvent modification or additive infusion, fully retaining two core active silk proteins: sericin and fibroin.
The micro-convex fiber structure on cocoon surface delivers mild physical exfoliation without scratching delicate facial skin. Rich sericin forms breathable semi-occlusive membrane to lock skin moisture and reduce transepidermal water loss (TEWL). Abundant natural amino acids in fibroin activate endogenous collagen synthesis, stabilize skin barrier and fade fine wrinkles. Passed full human patch irritation tests, this raw material is hypoallergenic, non-comedogenic and compatible with sensitive, fragile and post-procedure skin.
It works as triple-functional cosmetic additive: gentle physical exfoliant, long-lasting humectant and skin repairing conditioner, applicable for both rinse-off cleansers and leave-on serums, creams, masks. All batches come with complete global compliance certification to meet EU CosIng and FDA cosmetic ingredient standards.
