Skin Rejuvenation Peptides: GHK-Cu and GLOW

Collagen starts declining after 25. By 50, you're losing roughly 1% per year. Women lose up to 30% in the first 5 years after menopause (Brincat et al., 1987). Collagen creams work on the surface only. Peptides work from inside, at the gene expression level.

GHK-Cu: 4000 genes and collagen

[[GHK-Cu|24]] stimulates production of collagen types I and III. Maquart et al. (1988, FEBS Letters) showed a 70% increase in fibroblast collagen synthesis. Plus modulation of 4000+ genes involved in tissue repair, antioxidant defense, and inflammation reduction.

Two administration routes: subcutaneous (1-2mg/day, systemic effects) or topical (0.01-0.1% in carrier cream, local effects). Leyden et al. (2002, double-blind) showed improved skin thickness, reduced wrinkles, and better elasticity after 12 weeks of topical use.

A [[GHK-Cu|24]] 50mg vial at 1mg/day lasts 50 days of subcutaneous use.

GLOW: triple approach to skin

[[GLOW|23]] combines BPC-157 + TB-500 + GHK-Cu in a single 70mg vial. The formula logic:

• BPC-157 builds new blood vessels to skin tissue (more nutrition = better repair)
• TB-500 delivers repair cells to damaged areas
• GHK-Cu commands cells to produce collagen and triggers gene expression reset

Three mechanisms in one injection. For those who don't want three separate vials.

When to expect results

Collagen synthesis isn't instant. First changes (improved hydration, skin turgor) typically appear at 3-4 weeks. Meaningful texture and tone improvement: 8-12 weeks. Maximum effect comes from 8-12 week courses.

After procedures (laser, microneedling, chemical peels), GHK-Cu or GLOW accelerates recovery and improves the final result, since procedures create controlled damage and peptides amplify the repair response.
