The Study
Influence of Eicosapentaenoic Acid, an Omega-3 Fatty Acid, on Ultraviolet-B Generation of Prostaglandin-E2 and Proinflammatory Cytokines Interleukin-1β, Tumor Necrosis Factor–α, Interleukin-6 and Interleukin-8 in Human Skin In Vivo¶
This study looked at how a fish oil component might affect skin inflammation after sun exposure, but we don’t know how they did the experiment. So we can only say it might be connected — not that it definitely causes the change.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
Scientists tested if a fatty acid from fish oil (EPA) reduces skin inflammation after sun exposure.

Key takeaways
Summary
Based on the study abstract and findings.
- 1This suggests EPA might help reduce one part of sunburn inflammation, but not the whole response.
- 2EPA lowered a chemical called PGE2 (linked to inflammation) after sunburn, but didn't change other inflammation markers like IL-6 or TNF-alpha.

Higher consumption of omega-3 fatty acids from food leads to lower levels of prostaglandin E2 in humans.
Eating foods with anti-inflammatory properties lowers prostaglandin E2 levels in the human body.
In human skin exposed to UV-B radiation, eicosapentaenoic acid (EPA) is linked to lower levels of prostaglandin-E2, but it is not linked to changes in interleukin-1β, tumor necrosis factor–α, interleukin-6, or interleukin-8.
