Following a Mediterranean diet and taking omega-3 supplements may help reduce acne severity in patients with mild to moderate cases, according to new research published in the Journal of Cosmetic Dermatology.1 The study also showed that increased omega-3 levels led to improved clinical appearance and quality of life.
Acne is the most common skin condition in the United States, impacting 50 million people in the country each year. The condition mostly affects adolescents and young adults, but can continue into adulthood.2 Diets high in processed foods and dairy products are known to increase the risk for acne, but there has been little research on how dietary interventions could help alleviate the severity of symptoms.
Key Takeaways
- Adhering to a Mediterranean diet and taking omega-3 supplements can reduce acne severity and improve quality of life for patients with mild to moderate acne.
- Patients showed notable improvements in both inflammatory and non-inflammatory acne lesions, along with increased omega-3 index scores over the 16-week study period.
- Lifestyle interventions, including dietary changes and supplementation, should be viewed as valuable additions to traditional acne treatments, enhancing overall treatment efficacy and patient outcomes.
“In the pursuit of skin health, and particularly in a juvenile patient cohort, such as acne vulgaris, clinicians and patients are more than ever seeking treatment approaches that go beyond the conventional options of topical and systemic prescription medications,” the authors wrote. “As the understanding of the interplay between so-called exposome factors and skin health deepens, there is increasing evidence pointing to the pivotal role of nutrition in shaping dermatoses.”

Investigators from the University Hospital at Ludwig Maximilian University of Munich conducted a study to assess EPA and DHA levels in patients with acne, as well as to examine the effect of dietary interventions and supplementation on clinical severity. The single-center intervention study occurred over a 16 week period .
The study cohort included 60 patients who were not currently taking a prescription medication, of which 23 had acne comedonica and 37 had acne papulopustulosa. For the study, patients adhered to a Mediterranean diet that focused on plants and unprocessed, seasonal, nutrient-dense ingredients. Patients were encouraged to make homemade meals and limit ultra-processed foods, dairy products, and meat.
Study participants also took 2 different doses of oral algae-derived omega-3 supplements throughout the study period: 600 mg of DHA and 300 mg of EPA for weeks 1 through 8; and 800 mg of DHA and 400 mg of EPA for weeks 8 through 16. Patients were evaluated at 4 follow-up visits: baseline, week 6, week 12, and week 16.
