Acne is largely driven by inflammation. Recent research shows that omega-3 fatty acids—from sources like fish oil—may help reduce acne severity, particularly in those with moderate to severe conditions. Here's a simplified breakdown of how it works and how to use it smartly.
1. Why Fish Oil May Help Treat Acne
| Inflammation reduction |
Acne is an inflammatory skin condition; omega-3s such as EPA and DHA are known to reduce inflammation in the body, which is a key factor for acne development. |
|
Clinical data
|
A 2014 randomized controlled trial showed that supplementing with omega-3 and gamma-linolenic acid (GLA) reduced inflammatory acne by 40–50%. |
| Mixed evidence |
Several studies report varied outcomes—some participants improved, others worsened or saw no change. Benefits seem more pronounced in moderate to severe acne. |
2. Newest Findings (2024–2025)
|
- A 2024 intervention study combining a Mediterranean diet with algae-derived omega-3 supplements (EPA & DHA) showed significant acne improvement in patients who surpassed a target omega-3 level of ~8%.
- These results suggest dietary changes, when paired with omega-3 supplementation, can enhance skin health—but should complement, not replace, prescribed acne treatments.

3. Choosing the Right Source
| EPA & DHA over ALA |
While ALA (from flax, chia, walnuts) is plant-based, conversions to active forms (EPA/DHA) are limited. Focus on EPA and DHA from fish or algae sources |
| Quality matters |
Opt for supplements certified by the International Fish Oil Standards (IFOS) to avoid contamination and ensure purity. |
| Cod liver oil bonus |
Contains vitamins A and D—nutrients beneficial for skin—but requires cautious dosing due to potential for hypervitaminosis. |
4. How to Use Fish Oil for Skin Benefits
| Dietary first |
Incorporate 2–3 servings of oily fish weekly (e.g., salmon, mackerel, sardines) for natural omega-3 intake. *HealthlineAllure

|
Supplement wisely
|
- Look for products with standardized EPA + DHA amounts.
- Start with moderate doses (e.g., 1,000–2,000 mg combined EPA/DHA).
- Avoid exceeding FDA's upper limit: no more than 2 g per day from supplements; 3 g total including diet is tolerable *Wikipedia.

5. What About Risks?
| Possible side effects |
Some users report fishy aftertaste, nausea, or mild digestion issues. Taking supplements with meals can reduce these effects *Medical News TodayVerywell Health. |
|
Allergy caution
|
People with fish or shellfish allergies should avoid or choose algae-based supplements *Medical News Today. |
| High doses watch |
Large omega-3 intakes may increase bleeding risk or influence heart rhythm—consult a healthcare provider before high-dose use. |
