AboutAbout Acnera
Acnera is an acne and skin tracker for iPhone. It exists to answer one question most people with acne can't: what is actually causing my breakouts? It combines AI skin scans, a skincare ingredient scanner that checks your whole routine for conflicts, face-aligned before and after photos, and a quick daily log of sleep, water, stress, and your cycle.
Acnera is an independent app, published on the App Store by Juan Widiyanto. There's no big company behind it, which means the person reading your feedback is the person building the app.
How we write our guides
Acne advice online is full of confident rules with nothing behind them. Our guides and quizzes try to do the opposite.
Where our information comes from
- Peer-reviewed research, found and checked through PubMed and PubMed Central
- Clinical guidelines, especially the American Academy of Dermatology’s 2024 acne guidelines
- Patient information from the American Academy of Dermatology and DermNet
- Official product labeling, like FDA-required drug facts and prescribing information
Our rules
- Every statistic and health claim links to the source it came from.
- We describe research honestly: if a study only shows a link, we say "linked to", not "causes".
- We never invent numbers, quotes, testimonials, or reviews.
- We say when evidence is weak, mixed, or missing.
- Each article ends with when to see a dermatologist. Our guides are education, not medical advice.
How articles are made
We use AI tools to help research and draft. Before anything is published, every claim is checked against the source it links to, and anything we can't verify is cut. Our articles are not yet reviewed by a dermatologist, so treat them as a well-sourced starting point, not a diagnosis.
Updates and corrections
Each article shows the date it was last updated. When research changes or a reader spots a mistake, we fix it and update the date. Found something wrong? Tell us through Help & feedback or at support@acnera.app.
The app and our articles
Our guides mention Acnera where it helps you do what the article describes, like tracking a trigger or checking a product. The advice stands on its own whether or not you use the app.
Your data
Your skin data is used to power your own analysis and is never sold. You can delete your account and all of your data at any time. The details are in our privacy policy.
