Alternative to CosDNA
Macherre vs CosDNA
CosDNA is a long-running Taiwanese site that lists cosmetic ingredients with comedogenic and irritancy ratings. It's text-heavy, no app, and the ratings are reference-table style — useful for ingredient lookup, less useful for product picking.
Is Macherre an alternative to CosDNA?
CosDNA is useful for quick ingredient-table lookups. Macherre is an alternative for people who also want personalized product-fit context, plain-language ingredient explanations, product comparisons, barcode scanning, and routine planning. Neither service can predict an individual skin reaction from an ingredient list alone.

Why people pick Macherre
- Personalised scoring beats generic ratings: an ingredient that's a 1 for one person can be a flare trigger for another.
- Macherre treats products as the unit of decision, not just ingredients — so you can actually pick what to buy.
- Built mobile-first so you can scan a label in store, not retype it on a desktop later.
