Skincare doesn't need
to be complicated

Check what you already own before you buy anything else. These tools judge ingredients, never brands. Skinzy sells no skincare, and everything runs in your browser.

Why these tools are unbiased

Every verdict comes from Skinzy's ingredient database and the rules its routine builder follows, the same source as the ingredient conflict and combination guides. No product, brand or retailer is ranked, and nothing you enter leaves your browser.

Where our data has no explanation for a flag, the tools say so rather than inventing one, and anything they don't recognise is listed as unknown.

Want the routine built for your skin?

A checker can only judge the products you already own. A free scan scores five zones of your face and builds the shortest routine that covers what it finds: four steps or fewer, morning and night. No sign-up.
