The 2026 Dessinioti and Dreno review supports low-glycemic eating for fewer lesions in teens, but it does not prove dairy causes acne. Omega-3, Mediterranean, vegan, and low-dairy steps show only mixed or early support for adolescents and young adults.
Glycemic index ranks how fast foods raise blood sugar; glycemic load adds portion size. The review covers dairy, omega-3s, low-glycaemic, vegan and Mediterranean diets, as listed by Wiley/JEADV in 2026 early view the early-view listing. Contemporary Pediatrics notes nearly 85% of teens develop acne.

Does lower-glycemic eating help?
High glycemic index and higher glycemic load intake were linked to more acne onset and severity. The finding comes from a March 2022 JAAD International systematic review via NIH/PMC the systematic review. Low-glycemic diets cut lesions in several trials of teens and young adults.
Contemporary Pediatrics advises a food-and-skin log to test personal response. Favor whole grains, vegetables, and lean protein during the test. Do not cut whole food groups without a replacement plan.
Does dairy cause breakouts?
Observational studies link skim and low-fat milk plus whey protein to worse severity. Findings vary by sex and ethnicity. The March 2022 JAAD International systematic review found no randomized trials that prove cause.
The American Academy of Dermatology's 2024 acne guidelines made no specific diet rule, calling evidence on low-dairy, whey avoidance, omega-3s, and chocolate insufficient, as reported by Medscape on Sept. 26, 2025 the guideline report. Teens should not drop all dairy to chase clear skin. If you avoid dairy, replace calcium and vitamin D from other sources.
Do omega-3s and Mediterranean eating help?
Preliminary work links omega-3 and Mediterranean patterns to less acne. One 45-patient randomized trial of omega-3/GLA reduced lesions, according to Contemporary Pediatrics summarizing the Baldwin review on May 9, 2022 the Baldwin review summary.
A 2026 King's College London UK Biobank cross-sectional analysis tied Mediterranean adherence to less adult acne, especially in women. The signal is strongest for adult women, not teens. Treat this pattern as general healthy eating, not an acne prescription.
How should teens test food changes?
Most diet-acne studies enrolled people in their teens and twenties, so apply results to adolescents and young adults. Older adult data do not transfer directly. At the EADV 2025 debate, reviewer Clio Dessinioti said clinical evidence looks weak after genetics, weight, and other confounders, as reported by Medscape.
UK NICE guidance supports only a balanced diet. Use diet as support, not a substitute for proven care. Contemporary Pediatrics advises a short personal test with a food-and-skin log. Keep the log daily for several weeks:.
- Log meals, snacks, drinks, sleep, cycle, products, and breakouts.
- Favor whole grains, vegetables, and lean protein.
- If you avoid dairy, replace calcium and vitamin D.
