Yuka rates the bottle.
ClearSkin tracks your skin.
Yuka is a useful first filter, a quick hazard read on the products in your bathroom. ClearSkin is the second filter that matters more for breakouts: a daily log of the products and ingredients you actually use, correlated with what your skin does next.
Free. No account required.
Hazard score is not the same as your trigger
A product can score well on hazard and still break you out. Another can score poorly and sit on your skin without issue. Yuka cannot tell the two apart. ClearSkin watches the days you used each product and surfaces the ones that line up with breakouts.
Every product, every day, in one log
You log what you applied. ClearSkin keeps every product and ingredient alongside your sleep, stress, diet, and cycle, so a pattern shows up as data instead of a verdict on a single bottle.
On-device, no account, free
Everything stays on your phone. No sign-up, no community profile, no cloud sync, no paywall. You can use the entire app offline and delete it without leaving anything behind on a server.
Built around the research
Categories and prompts are based on what peer-reviewed studies show actually drives acne, not on a hazard methodology designed for general consumer health.
Frequently asked questions
Should I trust Yuka's product scores?
Treat them as a useful first filter, not a final answer. Hazard scoring tells you what a methodology says about a bottle in general. It does not tell you whether the products you actually use are working for your skin. ClearSkin is the second filter, tracking your routine against your breakouts to answer that one.
Does ClearSkin flag toxic ingredients?
No. ClearSkin does not assign hazard verdicts. The focus is acne, so the app surfaces the ingredients and habits that line up with your breakouts in your own data. If you want a hazard read on a product, that is what Yuka is for. The two tools answer different questions.
Is ClearSkin free?
Yes. There is no paid tier, no in-app purchase, no subscription. Every feature is available from day one. ClearSkin is designed to be used until you have your answer and then closed, not to keep you paying month after month.
Is my data private?
Yes. Everything stays on your phone. There is no account, no sign-up, no cloud sync, no telemetry, and no community profile. You can use the app entirely offline, and deleting it removes your log completely because nothing was ever stored on a server.
