- 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
