Acne is a common skin condition that troubles many, especially teenagers and young adults. Dealing with persistent breakouts can be frustrating, and often, the usual creams and pills don’t seem to help much. Research suggests that omega-3 fatty acids, abundant in foods like fish and certain supplements, might be key to reducing acne.
In 2024, researchers conducted a prospective intervention Study in Germany, and their findings were published in the Journal of Cosmetic Dermatology. The study explored the potential benefits of omega-3 fatty acids on acne, offering a new perspective on how diet can influence skin health. This important research could change how we approach acne treatment, emphasizing nutrition as a crucial factor.

The Study: Objectives And Methodology
Researchers investigated whether omega-3 fatty acids could reduce acne severity by increasing their levels in the body. They elevated the levels of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), specific omega-3 fatty acids, through dietary intervention and supplementation to observe the effects on acne severity and overall quality of life.
The study methodology included:
- This study involved 60 participants aged 12 and older, primarily women, who had mild or moderate acne and were not using any prescription medication.
- Over 16 weeks, participants followed a Mediterranean diet, emphasizing unprocessed, nutrient-dense foods such as vegetables, fruits, whole grains, and healthy fats while reducing ultra-processed foods, dairy products, and meat.
- They also took daily algae-derived omega-3 supplements (600 mg DHA and 300 mg EPA for the first 8 weeks, then 800 mg DHA and 400 mg EPA for the remaining 8 weeks).
- Participants visited the clinic at the start and then at 6, 12, and 16 weeks to track changes in their omega-3 levels and acne severity.
The researchers used the HS-omega-3 Index® to measure the percentage of EPA and DHA in the participants' red blood cells, aiming for a target range of 8-11%. Dermatologists assessed acne severity by counting inflammatory and non-inflammatory lesions and used standardized scales and digital photography to document the skin condition.
Facial sebum levels were measured to analyze skin oiliness. The study sought to understand the potential benefits of dietary changes and omega-3 supplementation on acne severity, aiming to improve both skin health and the overall quality of life for patients.
Key Findings of the Study
By the end of the 16-week study, nearly all participants showed a significant increase in omega-3 levels, reaching the target range of 8-11% on the HS-omega-3 Index®. This improvement was linked to a noticeable reduction in both inflammatory lesions (pimples and pustules) and non-inflammatory lesions (blackheads and whiteheads).
Participants with acne comedonica, which typically involves less severe acne with blackheads and whiteheads, experienced the most significant improvements compared to those with acne papulopustulosa, which involves more severe pimples and pustules. Many reported visible enhancements in their skin's appearance, including fewer lesions and better overall skin texture.
Participants who closely adhered to the Mediterranean diet and reduced their intake of ultra-processed foods and dairy products saw greater improvements in their omega-3 levels and acne condition. These dietary changes, combined with omega-3 supplementation, made participants feel more confident and happier with their skin, improving their quality of life. No significant adverse effects were reported, indicating the intervention was safe.
Significance of the Findings
Here are the significant findings from this study:
Dietary Impact on Acne
The study provides strong evidence that dietary intake, particularly omega-3 fatty acids, plays a crucial role in managing acne. This supports the notion that nutritional interventions can be an effective part of acne treatment.
Alternative to Prescription Medications
The significant improvements observed suggest that omega-3 supplementation can be a viable non-prescription treatment option, offering an alternative for individuals who prefer dietary adjustments over medications.
Enhanced Skin Health
The reduction in both inflammatory and non-inflammatory lesions highlights the potential of omega-3 fatty acids to improve overall skin health, making them a valuable addition to skincare routines.
Improved Quality of Life
Participants reported feeling more confident and satisfied with their skin, indicating that omega-3 supplementation can positively impact mental and emotional well-being, which is often affected by acne.
Guidance for Dermatologists and Individuals
The study offers valuable insights for dermatologists and individuals seeking alternative or complementary treatments, highlighting the importance of considering diet and supplementation in acne management.
Safe Intervention
The absence of significant adverse effects suggests that omega-3 supplementation is a safe intervention, making it a practical recommendation for a broad range of individuals.
Potential for Broader Applications
The success of this study opens the door for further research into the benefits of omega-3 fatty acids for other inflammatory skin conditions, potentially broadening the scope of dietary interventions in dermatology.
Limitations of the Study
The study group was small, with only 60 participants, and the duration was limited to 16 weeks, which may limit the generalizability of the findings. Larger and longer-term studies are needed to validate these results and understand the long-term effects of omega-3 supplementation on acne. Additionally, the study relied on self-reported dietary adherence, which could introduce bias or inaccuracies.
The study focused only on dietary changes and omega-3 supplements, making it more relevant to those with mild to moderate acne. It does not examine how these supplements might be used alongside prescription medications, often necessary for severe acne cases, nor does it evaluate their effectiveness for more severe acne. The absence of a control group receiving standard acne treatments also makes it difficult to compare the effectiveness of omega-3 supplementation against established therapies.
Functional Medicine Labs for Monitoring Omega-3 Levels
Functional medicine labs offer comprehensive tests to help you monitor omega-3 levels and make informed dietary adjustments. Here are some options available through Rupa Health:
Omega-3 Index Complete
Offered by Ayumetrix, this test measures the omega-3 index. It provides detailed information on EPA and DHA levels in the blood, as well as other omega-3 and omega-6 fatty acids, to help assess and optimize one's fatty acid status.
Fatty Acids Profile
Available through Doctor's Data, this test evaluates a comprehensive range of fatty acids, including omega-3, omega-6, and other essential fatty acids, offering an extensive overview of your fatty acid status and dietary needs.

Key Takeaways
- Omega-3 fatty acids can significantly reduce acne severity and improve quality of life. Incorporating a Mediterranean diet and algae-derived omega-3 supplements effectively boosts omega-3 levels.
- The study's promising results highlight the potential of dietary changes and supplements as a non-prescription acne treatment. Further research with larger and longer-term studies is needed to confirm these findings and understand the long-term effects.
- Regular monitoring of omega-3 levels through functional lab tests can help individuals optimize their intake and ensure that omega-3 levels remain within the target range for maximum skin health benefits.
