The verdict

Yes — as a small additive in a topical routine that already does the heavy lifting (sunscreen, retinoid).

By source — cost, legality, risk
  • Cosmetic OTC (The Ordinary, Beauty Pie, Paula's Choice)
    $25–$70 per serum
    OTC cosmetic ingredient
    Lowest. Concentration and vehicle drive efficacy more than brand.
  • Compounded cosmetic
    $60–$150
    OTC pharmacy (cosmetic, not drug)
    Penetration enhancers may be added; not a 503A drug compound.
  • RUO peptide powder
    $10–$30/mo
    Sold for research only
    Highest. DIY; stability and sterility unverified.
  • Gray-market overseas raw
    $4–$8/mo at cosmetic dose
    Illegal to import for human use
    Highest. Gray channel rarely used for topical cosmetic doses; no meaningful demand.
