Omega-3 Fatty Acids for Acne Reduction
Omega-3 supplementation (EPA+DHA) has shown reduced inflammatory and total lesion counts in small RCTs, plausibly via reduced leukotriene B4 and systemic inflammation. Evidence is promising but not definitive.
Overview
Verdict
Small trials suggest omega-3s reduce inflammatory acne lesions, but study quality is variable.
How It Works
Dosing & Protocol
Typical dose
- Recommended dose
- EPA+DHA 2 g/day with a meal.
- Expected timeframe
- 8–12 weeks.
Protocol
- form
- Fish oil, or algal oil for vegetarians. Check the EPA+DHA content rather than total oil - a 1,000 mg capsule often contains only 300 mg of omega-3
- duration
- 10-12 weeks; skin turnover means nothing is visible before 8 weeks
- co factor
- Take with a fat-containing meal, which substantially improves absorption, and refrigerate to limit oxidation. Evidence is mixed and limited. A small randomised trial of 2,000 mg/day EPA+DHA over 10 weeks in acne reported reduced inflammatory lesion counts in some participants, and a further small study found improvement alongside reductions in inflammatory markers - but other participants worsened, sample sizes were very small, and results have not been replicated in adequately powered trials. The rationale is plausible: EPA competes with arachidonic acid, shifting eicosanoid production towards less inflammatory mediators and generating resolvins, and acne is substantially an inflammatory condition.
- titration
- Up to 2,000 mg/day EPA+DHA; the small acne trials used around 930-2,000 mg/day
- starting dose
- 1,000 mg/day combined EPA+DHA with the largest meal of the day

The adjuvant treatment role of ω-3 fatty acids by regulating gut microbiota positively in the acne vulgaris
Omega-3 supplementation as adjuvant therapy reduced inflammatory acne lesions and modulated gut microbiota.
