Ranked by evidence

The best treatments, by efficacy grade

Not "editor's picks" — a ranking by what the formula can actually do. Every treatment below is graded on its active, the dose, and the evidence, with the receipts one tap away. Top grade in this category right now: B.

How this ranking is built

Each treatment is scored on its disclosed actives versus published effective-concentration thresholds, the formulation, and any product-specific study — the same open rubric we grade everything on. You can't pay to move a spot. Most products in this category don't disclose enough to grade at all; those are excluded here.
