A 2026 scoping review of 105 studies found acne AI focuses almost entirely on image-based diagnosis, not treatment guidance. That focus raises direct privacy questions for people who upload facial acne photos to apps. A scoping review is a broad survey that maps what research exists and where gaps remain.
The review was published online Nov. 6, 2025 and in print in 2026, according to the International Journal of Dermatology via Wiley in the review in the International Journal of Dermatology. For readers with acne, the takeaway is practical: assume your selfie may identify you, may train a model, and may lack medical oversight.

What did the 105 studies actually test?
Most work tested whether AI could spot acne in photos. Of 105 articles, 101 addressed diagnosis only and 10 addressed management only, with 6 covering both. Treatment advice remains much less studied than image diagnosis.
That imbalance matters for app users. An app may label pimples, blackheads, or severity grades without proven guidance on what to do next. Ask whether the tool offers diagnosis, management, or both, and who checks its output.
Who may get less reliable results?
Only 14 studies reported patient skin color or ethnicity. Only 4 included skin-tone data when building the model. That limits confidence for users with darker skin.
Acne can look different across skin tones, and inflammation or post-acne marks may be read less well. If you have brown or Black skin, treat app scores as more uncertain. A clinician who sees diverse skin in person can give a safer read.
Why don't acne selfies get HIPAA protection?
Health information on your own phone often lacks HIPAA protection. The U.S. Dept. of Health and Human Services states HIPAA Rules generally do not cover data stored on personal phones or entered into personal-use apps, described in the HHS cell-phone privacy guidance. Protection usually applies only when the app was provided by a covered clinic or its business partner.
Separate federal rules still reach many health apps. The Federal Trade Commission says its Health Breach Notification Rule, amended effective July 29, 2024, covers non-HIPAA personal-health-record vendors, explained in the FTC compliance guide for the Health Breach Notification Rule. Unauthorized sharing with advertisers or analytics firms can count as a notifiable breach. Enforcement has been real. FTC actions penalized GoodRx with $1.5M, BetterHelp with $7.8M, and issued orders against Flo Health and Premom over sharing of sensitive health data. Face photos deserve the same caution, because they can identify you directly.
What should you check before uploading?
No consumer apps claiming to diagnose skin conditions have FDA approval, warns the American Academy of Dermatology. A 2024 JAMA Dermatology review of 41 AI dermatology apps found none FDA-approved.
Accuracy and safety are therefore unguaranteed. Use this short check before you tap upload: If the company will not answer in writing, do not upload close-up face images. Choose in-person care or a clinic-provided portal instead.
- Demand written terms for photo retention, deletion, and model training.
- Require opt-in consent for any sharing, with no ad-tracker disclosure.
- Ask whether a licensed clinician reviews AI results.
- Save baseline and follow-up photos outside the app when possible.
