Questions
Are dupes really the same?
Sometimes very close, never identical. We compare the ingredient lists and score the overlap in key actives, their concentration where known, and the vehicle. Every match score shows what is shared and what is missing.
How do you pick them?
We start from the brand ingredient list, identify the active ingredients doing the work, then search for cheaper products that contain the same actives at comparable levels. The scoring method is public on the methodology page.
Do you earn commission?
Yes. Buy links to Amazon are affiliate links and we earn from qualifying purchases at no extra cost to you. The ranking does not depend on commission: scores come from the formulas.
Is this medical advice?
No. This is general information about cosmetic products. Talk to a dermatologist about skin conditions, pregnancy, or prescription treatments.
How often is the data updated?
Prices and formulas change, so we re-check on a regular schedule and show the date of the last check on product pages and the finder. Always confirm the price and ingredient list on the seller page before buying.
