No fear scores. Just receipts.
Skincare claims, checked against the actual studies.
Paste any ingredient list. We'll tell you what each ingredient does, which human trials back it — and how much those trials should be trusted.
How we grade evidence
Strong evidence
Multiple independent trials or a meta-analysis agree
Good evidence
One or two solid randomized trials
Early evidence
A small trial, or mostly lab data so far
Not enough evidence
No meaningful human data yet
Grades apply to an ingredient for a specific concern, at the concentrations that were actually studied — never as one blanket score. Apps that flash red warnings are scoring hazard lists; we grade whether something has been shown to work.
