  • GHK-Cu topical (1.5%)
  • TGF-β activation, collagen upregulation, VEGF signaling
  • RCT data shows 28–31% faster healing, 41% scar width reduction
  • $60–$120
  • Requires twice-daily application; avoid before complete incision closure
  • Strongest evidence for localized incision healing and scar quality improvement
  • GHK-Cu subcutaneous (2–5 mg/day)
  • Systemic signaling molecule elevation, multi-tissue repair support
  • Limited RCT data; mechanistic evidence strong; observational reports positive
  • $180–$300
  • Requires reconstitution, refrigerated storage, injection comfort
  • Best for extensive internal tissue trauma (abdominal, joint surgery); less data than topical
  • Silicone gel sheets
  • Physical barrier reduces tension and moisture loss at scar site
  • Cochrane review: modest scar width reduction (15–20%); no healing acceleration
  • $40–$80
  • Must be worn 12+ hours daily; adhesive irritation common
  • Effective for scar appearance post-healing; does not accelerate initial wound closure
  • Vitamin E topical
  • Antioxidant activity; proposed collagen support
  • Weak evidence; some studies show no benefit or worsening outcomes
  • $10–$25
  • Low barrier to use; widely available
  • Poor risk-benefit profile. Inconsistent results, potential for contact dermatitis
  • BPC-157 injectable
  • Proposed angiogenesis and fibroblast activation
  • No peer-reviewed human trials; rodent data suggests benefit
  • $120–$200
  • Legal gray area; no standardized dosing; requires injection
  • Mechanistically plausible but lacks human clinical validation; consider for research contexts only
