Skincare dupes: how to find a cheaper alternative that works

By The regimen team · June 24, 2026 · 1 min read

A "dupe" is a cheaper or easier-to-find product that delivers similar results to a pricier one — because what matters most is the active ingredients and formulation, not the brand or packaging.

What makes a real dupe

  • The same key actives at meaningful concentrations (e.g. both are 10% niacinamide, or both are encapsulated retinol).
  • A similar overall formula — humectants, occlusives, and texture in the same ballpark.
  • Not just a similar claim on the box.

What doesn't make a dupe

Matching marketing language ("brightening," "anti-aging") tells you nothing. Two "brightening serums" can have completely different actives. Always compare the ingredient list.

Let a tool match the ingredients for you

Reading INCI lists side by side is tedious. regimen's product pages include a "Similar products & dupes" section that ranks alternatives by how closely their active-ingredient and ingredient fingerprint matches — so you can find a cheaper option that genuinely performs. Browse the product catalogue and open any product to see its dupes.

FAQ

Are skincare dupes as good as the original?

Often, yes — if the actives and formulation are similar. Price frequently reflects branding and packaging more than performance.

How do I know if two products are dupes?

Compare their active ingredients and the top of their INCI lists. A tool that scores ingredient similarity makes this much faster.
