The 2026 acne AI review means people with skin of color cannot yet trust AI acne tools as much as people with lighter skin can. The tools diagnose acne well on average but were rarely built or tested across darker tones. A scoping review is a broad survey that maps what published studies tested and what they left out. The International Journal of Dermatology review mapped 105 AI-acne articles and found a sharp skin-tone gap, with the review summary reporting 96.2% addressed diagnosis only.

What the 105-study review found
Ensemble models performed best in the review and offered consistent remote diagnosis and management, according to the International Journal of Dermatology. That strength applies mainly to the cases researchers actually included. Only 14 of 105 studies reported patient skin color or ethnicity, and only 4 included a full spectrum of diverse skin tones, according to the PubMed record for the review. The International Journal of Dermatology published the review online Nov.
6, 2025. The review also flagged repeated limits that reduce trust. An International Dermatology Conference program summarizing the review lists small datasets, variable image quality, skewed Fitzpatrick representation, proprietary datasets, and almost exclusive focus on facial images. Fitzpatrick means a scale that groups skin from lightest to darkest.
Why darker tones keep missing from AI
The acne gap reflects a wider dermatology data gap. A Lancet Digital Health analysis reported by NYTech.Media examined 21 open skin-image datasets with over 100,000 images and found just over 1,400 images had ethnicity information, with only 11 images in the two darkest Fitzpatrick categories, according to the report on the analysis. Medscape reports dermatologist Jules Lipoff warned in 2026 that darker skin tones remain significantly underrepresented in training data.
He warned the tools may misdiagnose darker skin and cause incorrect treatment. Patient Care Online reports researchers at New York teaching hospitals found widely used generative AI dermatology images lacked diagnostic accuracy and overwhelmingly underrepresented skin of color. The researchers warned the pattern risks perpetuating disparities.
Why the error matters more for darker skin
Acne looks different and heals differently across tones. Redness may appear subtler on darker skin, while brown or purple marks stand out after breakouts fade. People with darker skin face far higher risk of post-inflammatory hyperpigmentation, Harvard Health Publishing reports.
Those dark spots can last months to years and outlast the acne itself, according to Harvard's guidance on acne in darker skin. A missed or delayed acne diagnosis therefore carries extra cost. More inflammation can mean more lasting marks, even after the original pimples clear.
How to use acne AI more safely
Treat an app result as a starting note, not a diagnosis. Use it to prepare for a clinician visit, especially if you have brown or Black skin, frequent dark marks, or acne on the chest, back, or scalp.
An npj Digital Medicine review of the first AI-enabled primary-care skin-cancer device stresses diverse training data and post-market surveillance because poor darker-skin performance risks re-entrenching bias. Ask what follow-up the acne tool offers if your skin was not in its training set.
- Share clear photos in daylight and note your skin tone concern directly
- Ask whether the tool was tested on darker skin tones
- Track breakouts, color changes, and dark marks with dates
- Seek in-person care for fast spread, pain, scarring, or a mismatch with the AI result
- Ask a dermatologist experienced with skin of color about mark prevention
