Omega-3 research: Skin & eyes
Explore what omega-3 studies tell us about skin & eyes. Start with a specific outcome: findings for one condition do not automatically apply to another.
These summaries distinguish evidence confidence from benefit. Some questions remain unscored while full appraisal is pending.
Can fish oil improve psoriasis severity?
Fish oil alone has not shown a clear severity benefit in pooled trials. Reviews suggest possible adjunctive effects with conventional treatment, but those findings do not establish stand-alone efficacy.
Mixed findings · 2/4 provisional confidence
Could topical omega-3 help eczema?
Topical preparations have been explored for inflammatory skin conditions. The available research is preliminary and does not establish a standard eczema treatment.

Do omega-3 supplements relieve dry-eye symptoms?
A large trial found no advantage over its control, while pooled reviews report varied results across dry-eye causes and formulations. A universal benefit is not established.
Mixed findings · 2/4 provisional confidence
Do EPA and DHA supplements slow progression to advanced AMD?
Adding EPA and DHA in AREDS2 did not reduce progression to advanced age-related macular degeneration. Observational links with fish intake do not reverse this trial finding.
No clear benefit demonstrated · 3/4 provisional confidence
Interpret the research
A laboratory change, symptom improvement and prevention of disease are different outcomes. Study design, formulation, dose, duration and baseline health all affect interpretation.
