Skincare Replacement Guide

No match
scores.

Two products can share most of an ingredient list and still feel different. So our replacement guides say what matches, what does not, and what is unknown.

How a candidate is reported

Illustrative: a hypothetical light gel moisturizer and one candidate

Matches

  • No fragrance listed
  • Described as a gel

Checked on the label and listing

Does not

  • Jar, where the original was a pump

A real difference in how exposed it is in use

Unknown

  • Finish
  • Richness
  • How it layers under sunscreen

Only trying it, or a clear firsthand report, tells you

Same names.
Different results.

Small studies, mostly lab or short-term work, and not studies of dupes. They point the same way: details an ingredient list does not show can change how a product performs.

  • Hidden: grade

    Hyaluronic acid at five molecular weights

    All improved hydration in a 60-day trial of 76 women. Only the two lowest weights reduced wrinkle depth.

  • Hidden: one emollient

    Swap one oil, change the spread

    Emulsions differing only in one emollient spread significantly differently, on skin and on instruments.

  • Hidden: emulsifier

    Same filters, different SPF

    In four sunscreen formulas, emulsifier type and amount affected the measured SPF.

  • Hidden: composition

    Barrier went opposite ways

    Over seven weeks in 78 volunteers, simplified creams increased water loss while a conventional cream had the opposite effect.

Why your list might look different

2017 · EU

Methylisothiazolinone banned in leave-on products, while North American rules stayed looser. A regional version can be a different formula.

From August 2026 · EU

56 more fragrance allergens must be named on the labels of products placed on the market. Some lists will grow with no change to the formula.

Every guide opens with a short answer.

When to see a clinician first

If a clinician chose the original for a diagnosed condition, or patch testing showed ingredients you must avoid, ask them or a pharmacist before switching, and bring both ingredient lists.
