R-(SH-POLYPEPTIDE-22 DECAPEPTIDE-40).

This single-chain recombinant peptide is precisely engineered through E. coli fermentation, formed by the genetic fusion of sh-Polypeptide-2 and Decapeptide-40. Its multifaceted mechanism of action includes: 1. **Skin Conditioning & Protection**: It actively improves the skin's condition, contributing to a softer, smoother, and more hydrated feel. Simultaneously, it forms a protective barrier on the skin surface, shielding it from external aggressors such as pollution and UV radiation, thereby maintaining epidermal integrity. 2. **Cellular Regeneration & Wound Healing**: The sh-Polypeptide-22 component acts as a synthetic analog of human transforming growth factor beta 1 (TGFβ-1). It significantly stimulates cell proliferation and differentiation, promoting efficient wound healing through the activation of epithelial cells and fibroblasts. 3. **Extracellular Matrix Synthesis**: It is a potent stimulator for the synthesis of crucial structural proteins including collagen, elastin, and fibronectin, which are essential for maintaining skin firmness and elasticity. 4. **Microcirculation Enhancement**: The peptide encourages renewal of microvascular cells, leading to improved blood microcirculation within the skin, supporting nutrient delivery and cellular vitality. 5. **Pigmentation Modulation**: It demonstrates an inhibitory effect on tyrosinase activity, which is key in melanin production, thereby contributing to a reduction in hyperpigmentation and offering a skin brightening benefit. 6. **Anti-inflammatory & Immunomodulatory**: By suppressing pro-inflammatory cytokines, it exerts an anti-inflammatory effect and plays a role in regulating the skin's immune responses.
