System Verdict
This is a solid peptide lash serum, not a miracle grower. The efficacy score is driven by a genuinely relevant cluster of peptides near the top of the INCI, plus panthenol, glycerin, caffeine, and supportive conditioning agents that can help lashes and brows look thicker, less brittle, and better hydrated; it is not driven by any marketing-only gimmick. The score is held below the top range because this is still a cosmetic support serum, not a prostaglandin analog or a drug-like growth treatment, and the botanical/supporting ingredients are secondary rather than dominant actives.
