SH-POLYPEPTIDE-8.

Valuable / HUMECTANT, SKIN CONDITIONING

SH-POLYPEPTIDE-8 is a sophisticated synthetic growth factor analog engineered to promote cellular-level skin rejuvenation. By mimicking natural Platelet-Derived Growth Factor (PDGF), it actively supports skin repair, boosts essential structural proteins, and significantly enhances overall skin vitality and youthful appearance.

Science

Mechanism of Action

As a recombinant analog of human Platelet-Derived Growth Factor (PDGF), SH-POLYPEPTIDE-8 operates by mimicking the biological activity of endogenous PDGF, a crucial signaling protein for normal skin growth, healing, and regeneration. Its multifaceted action includes accelerating natural healing processes and significantly reducing inflammation by modulating TNF-α activity. Furthermore, it precisely targets and decreases the activity of MMP2 and MMP9, enzymes responsible for degrading the extracellular matrix, thereby preserving skin integrity. It actively stimulates the biosynthesis of collagen and elastin, foundational proteins for skin firmness and elasticity, and promotes the generation of new skin cells, leading to a visible reduction and prevention of lines and wrinkles. Additionally, it contributes to skin hydration and conditioning through its inherent humectant properties.

Key findings

  1. 01 General research indicates SH-POLYPEPTIDE-8 enhances skin healing rates, reduces TNF-α-induced inflammation, and decreases the activity of matrix metalloproteinase enzymes (MMP2 and MMP9). It also actively boosts the production of collagen and elastin, improving skin firmness and elasticity, and stimulates new skin cell generation to reduce and prevent wrinkles.
  2. 02 In a 30-day study involving 20 healthy Caucasian women (aged 35-55), a blend of growth factors including SH-POLYPEPTIDE-8, used in conjunction with home-based micro-needling, demonstrated significant improvements: an 11.8% increase in skin elasticity, a 2.5% increase in luminosity, and a substantial 110% increase in skin brightness. Concurrently, skin sagging was reduced by 6.3%.
