Free tool
Compare two skincare products, side by side
Pick two or three products and Macherre lines them up: shared ingredients, unique ingredients, key actives, ratings and sensitivities — so you can choose by formula, not by marketing.
Why use this tool
Ingredient diff
A side-by-side view highlights shared ingredients, ingredients only in product A, and ingredients only in product B — at a glance.
Key actives & concentrations
Spot which product actually delivers more vitamin C, retinol or niacinamide, with concentrations and pH where our catalog has them.
Sensitivity flags
Fragrance, drying alcohols, common allergens and anything you've personally flagged are surfaced per column so nothing slips through.
How it works
- 1
Shortlist your candidates
Save interesting finds from search, dupes, or ingredient-led rabbit holes — anything you might actually buy.
- 2
Open compare
From any product page in the Macherre app, tap a second product to add it to the comparison tray.
- 3
Read the diff and decide
Scan shared bases versus real differentiators, then buy or patch-test with confidence — no more decision paralysis.

Choosing between two serums or two moisturizers usually comes down to invisible differences: an extra peptide here, a heavier occlusive there, a preservative your skin doesn't tolerate. Macherre's compare tool lays the ingredient lists side by side and shows you exactly what overlaps, what's unique to each formula and where the meaningful differences sit — so you stop deciding based on bottle design and influencer hype.
When you're signed in with a skin profile, comparisons can also weight personal fit: ingredients you've flagged as triggers, sensitivities you've logged, and the actives that matter for your goal. Pair compare with the dupes tool to find affordable swaps, or with the ingredient checker for a deeper dive on any line that catches your eye.
Frequently asked questions
How many products can I compare at once?▼
Two or three products at a time. That's the sweet spot where the diff stays readable on a phone — beyond that, the table gets too dense to be useful.
Can I compare products from different brands?▼
Yes. The compare tool is brand-agnostic — line up a luxury serum against a drugstore one, a Korean cleanser against a French one, whatever you want.
Why don't prices always show up?▼
Pricing comes from regional retailer listings. We show prices and links when they're available in your market, and gracefully omit them when they aren't.
Are reformulated INCI lists kept up to date?▼
We refresh ingredient lists when verified updates come through, but reformulations sometimes ship before they hit databases. Always cross-check the printed packaging in front of you.
Can I compare sunscreens or makeup products?▼
Yes — sunscreens, foundations, moisturizers, cleansers and serums all work. UV filters, pigments and actives appear like any other INCI line in the diff.
Will the tool tell me which one is better?▼
There's no universal winner. The compare view shows you the facts; if you're signed in, personal scoring reflects your own skin profile so you can decide based on real fit, not generic popularity.
