Syndecan-1 is a transmembrane heparan sulfate proteoglycan. The heparan sulfate side chain on the molecular surface of syndecan-1 can bind a series of ligands such as cell adhesion molecules, matrix molecules, growth factors, enzymes and enzyme inhibitors to regulate the interaction between cells and microenvironment in the form of coreceptors. It participates in the regulation of a series of physiological activities such as tissue differentiation, growth and development, angiogenesis and tissue regeneration.

AcetylTetrapeptide-11 has the effect of anti-wrinkle, anti-aging, improving skin bonding strength, firmness and elasticity, and improving skin quality. Also used in face care and body care Face, neck and hand care products. Can be added to the beauty and skin care products, such as moisturizing lotion, day cream and night cream, eye essence, can give the skin a unique sense of use.
Type XVII collagen is the core protein of hemidesmosomes and plays a key role in the junction of the epidermis and the epidermo-dermal junction. With aging, the synthesis of Syndecan-1 decreases, the adhesion between epidermal cells decreases, the epidermal layer loses tolerance and gloss, and the skin is dry, peeling, and loose, which is easily damaged by various small friction and shock.
