The 2026 review in the International Journal of Molecular Sciences warns against restrictive regimens because they can raise eating-disorder risk without clear skin benefit. Restrictive regimens mean strict bans on dairy, sugar, or whole food groups, and the review instead urges sustainable healthy eating alongside standard treatment. Teenagers face this pressure most directly. Acne affects about 85% of adolescents ages 12–24, according to American Academy of Dermatology guidance summarized by Newswise, so diet claims spread fast in the group least helped by extreme rules.

Which foods are linked to acne?
Observational and small intervention studies repeatedly associate high-glycemic-load diets with greater acne severity. The same studies also flag skim and low-fat milk, whey supplements, and a high omega-6 to omega-3 ratio, as summarized by Dermatology Times. Low-glycemic-load patterns show the most actionable benefit signal among these options.
These are associations, not proof that one food causes breakouts. A sugary drink pattern may track with missed sleep, stress, or inconsistent treatment. That overlap makes strict bans a poor test of what actually helped.
Why do experts still reject strict acne diets?
The UK NICE acne guideline NG198 finds insufficient evidence to recommend any specific diet for acne. NICE explicitly declined a diet recommendation because limited benefit did not outweigh eating-disorder concerns in young people, as explained in its rationale and impact statement.
That judgment matters because teen eating patterns are still forming. A ban that sounds simple can reduce calcium, protein, energy, or social meals. When benefit is uncertain and harm is plausible, experts choose the safer default.
Why does this warning focus on teens?
Teens combine high acne rates with high exposure to "clear-skin diet" videos and lists. Restriction can feel like control during months when breakouts feel random. It can also shift attention away from treatments with stronger support.
Eating-disorder risk makes that shift costly. Early food fears can persist after acne fades. Protecting a flexible relationship with food is part of protecting long-term health.
What can teens do instead of restricting?
Choose a steady, sustainable pattern: regular meals, fiber-rich carbs, protein, fruit, vegetables, and water. Keep proven acne care going rather than pausing it to test food rules.
Give any diet change several weeks before judging it, and avoid adding new bans when skin flares. Bring that short log to a clinician or dermatologist and ask what to keep, adjust, or stop.
- Keep dairy, bread, or sweets unless a clinician advises a trial change
- Change one habit at a time, such as fewer sugary drinks or fewer whey shakes
- Track breakouts, sleep, stress, and treatment use in a short note
- Seek medical care for painful, persistent, scarring, or possibly hormonal acne
