sumsum — skincare scanner

Most of us can't pronounce half the ingredients on our skincare labels. sumsum reads them for you and tells you what they actually mean.
sumsum operates on the precautionary principle: if there's credible scientific concern about an ingredient from animal studies, in-vitro research, or epidemiological data, you deserve to know, even if regulators haven't caught up yet. Every rating is sourced from IARC, EU SCCS, NTP, and FDA data. No guesswork, no scare tactics. Just science, sources, and your choice.
FIVE WAYS TO CHECK ANY PRODUCT
Barcode, front of package, ingredient list photo, manual entry, or search by name. Works in most languages.
WHAT ONE SCAN TELLS YOU
A safety score from 1 to 10. Every flagged ingredient shows its severity, hazard category, and the published source behind the flag. Over 350 ingredients reviewed across carcinogens, endocrine disruptors, allergens, preservative concerns, and contaminants. Plus cleaner swap suggestions so you know what safer alternatives to look for next time you shop.
BUILT AND VERIFIED BY THE COMMUNITY
Every ingredient is checked against a 28,000-entry cosmetic ingredient dictionary. As more people scan the same product, ingredient lists are cross-verified and accuracy improves. You're not just scanning for yourself, you're helping build a cleaner database for everyone.
