The same formula. For less.

How the score works

  1. 100 points per original

    We split each luxury formula into three to six standout parts and share 100 points between them.

  2. 0 to 100 for what a build earns

    A shelf part earns a standout's points only when it truly covers it. Partial cover earns partial credit, and some originals have a ceiling below 100.

  3. 60 or more before we show a saving

    We only put a saving on a build that scores 60 or more and has every part priced. How we score.

Looking for hair care?

The same method now covers hair: Olaplex, Briogeo, Moroccanoil, OUAI, rebuilt from shelf lines such as Not Your Mother's. See the hair builds.

Every claim links to the study

If we say an ingredient works, there is a citation chip next to it. Click it and you land on the paper in our evidence library: title, authors, journal, study type and the finding in one line.

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.
