- How does the cosmetic scanner work?
- Point your camera at the barcode on a makeup, skincare or personal-care product. The barcode is read on your device, then looked up in the free Open Beauty Facts database, which returns the product's INCI ingredient list. The tool decodes each ingredient — naming it and its function — and flags the ones a regulator restricts or that are commonly avoided. No barcode, or a product that isn't in the database? Read the ingredients list with your camera, or paste it in.
- What do the flags mean?
- Two clearly-separated kinds. A red “regulatory flag” appears only when a named authority has acted, shown with its source — for example the EU banned titanium-related colours or Lilial, methylisothiazolinone is EU-restricted in leave-on products, and IARC classifies BHA as possibly carcinogenic. A softer amber “commonly avoided” flag marks ingredients many shoppers skip — sulfates, most parabens, silicones, fragrance — a note, not a claim of harm. Everything else is simply named with its function.
- Where does the ingredient data come from?
- Product ingredient lists come from Open Beauty Facts, an open, crowd-sourced database (ODbL) — the cosmetics sister of Open Food Facts. The flags are grounded in EU CosIng restrictions, IARC classifications and FDA actions, each shown with its source. Coverage varies, and some products (especially regional ones) may be missing or incomplete.
- Does it work for Indian and other regional products?
- The barcode always scans; whether the product is found depends on Open Beauty Facts' coverage, which is thinner for regional brands. When a product isn't found, read the ingredients list with your camera or paste it in — the same decoding and flags run on whatever ingredients you give it.
- Is anything uploaded or tracked?
- No. Reading the barcode and reading an ingredients photo both happen entirely on your device. When you look up a product, only the barcode number is sent to Open Beauty Facts — never a photo, never anything personal, and there's no account.
- Is this medical or dermatological advice?
- No. This is general, informational ingredient decoding from crowd-sourced data and public regulatory sources — not medical, dermatological or safety advice. A flag isn't a verdict of harm, and an unflagged product isn't a guarantee. Patch-test new products, and see a professional for skin concerns.
