Understanding your skin, made simple and private

Why we built it

Most people sit somewhere between “this is probably nothing” and “should I get this looked at?” — often for weeks. dermatrix.life is built for that gap: a fast, judgment-free way to get informed about a skin concern before deciding whether to seek professional care. It is a starting point, not a verdict.

The technology behind it

dermatrix.life is powered by MedGemma, an open medical AI model developed and released by Google, which we apply specifically to skin. On a dermatology benchmark (US-DermMCQA), MedGemma models have scored around 72% — well above a general-purpose model of the same size — but a benchmark is a reference point, not a measure of how precisely it reads your individual photos.

dermatrix.life is an independent service that uses this model; it is not made, endorsed, or reviewed by Google. And we want to be upfront about one thing in particular: your assessment is generated automatically by AI. It is not reviewed by a doctor or any other medical professional. We think being honest about that matters more than sounding authoritative.

What dermatrix.life is not

• It is not a medical service and does not provide a diagnosis or medical advice.
• It is not a substitute for evaluation by a qualified dermatologist or physician.
• It cannot assess possible skin cancer, new or changing moles, or anything needing a physical exam, lab tests, or a biopsy — please see a doctor for those.
• Its read depends on your photos: image quality and lighting affect what it can observe.

Who it’s for

dermatrix.life is for adults — you must be 18 or older to create an account and use the service, and we ask you to confirm your age when you sign up. It is not intended for minors, and you should not upload images of anyone under 18. You can read the full requirement in our Terms.

Your privacy

We are privacy-first by design. We never ask for your real name; your email is hashed after verification, so it is never stored in plain text; and your photos are kept in a private, access-controlled place and deleted within 24 hours of analysis. We don’t sell your data or share it with advertisers. You can read the full privacy policy for details.
