your skincare, summarized
Know what's actually on your face.
The average skincare product has 25 ingredients. Most of us can pronounce three. sumsum reads the rest, so you can see what's really in your routine, and decide what stays.

"Clean," "natural," "dermatologist-approved" are not regulated terms. The real answer is on the back of the bottle in print you can barely read. sumsum makes it readable.

What one scan tells you
Every product gets a 1 to 10, calculated from a fixed database of 150+ flagged ingredients with severity ratings from EU CosIng, SCCS, IARC, and EWG. Same product, same score, every time.
Every flagged ingredient comes with a severity level, a category (carcinogen, endocrine disruptor, allergen, irritant), a plain-English reason, and a source you can check.
15 common swaps, from SLS to parabens to phthalates, with safer alternatives and why they're better.
Pregnant, thyroid condition, acne-prone, sensitive? sumsum flags what matters for you specifically, not a generic list.
More than a scanner
Every product you own in one place, with a single shelf-health score so you can see how your routine is actually doing.
Built in the right order: cleanser, toner, serum, moisturizer, SPF, with a streak to keep it going.
