How the grade works

Each ingredient gets a score out of 10 from its published clinical studies — not brand claims. A = 8–10, B = 4–7, C = 0–3.

The five criteria & the grade definitions
CriterionWhat earns the pointsPoints
Human clinical trialsRandomized controlled trials or meta-analyses in people, measuring the claimed effect0–2
Guideline or regulatory recognitionNamed in clinical guidelines (e.g. American Academy of Dermatology) or approved as a drug for the condition0–2
Independent replicationPositive results repeated by research groups with no stake in selling the ingredient0–2
Evidence at cosmetic useTrials tested a topical cosmetic at realistic strengths — not only injections, prescription doses, or in-office peels0–2
Safety recordLong, well-documented tolerability at cosmetic strengths, with known and manageable side effects0–2
A

Strong · 8–10 points. Multiple trials or meta-analyses, often guideline-backed. The closest thing skincare has to a sure bet.

B

Moderate · 4–7 points. Real human evidence, with gaps — smaller studies, narrower claims, or formulation caveats. Plausible and partly proven.

C

Early · 0–3 points. Mostly lab, animal, or injection studies. Popular in marketing well before the cosmetic evidence exists.

Keeping it honest

Studies test ingredients, not products — a high grade means the ingredient is proven, not that every product with it works.
