We don’t often think of fish oil as a skin supplement — but maybe we should.
While omega-3s aren’t a direct “wrinkle cure,” studies over the past five years have revealed their power in fighting internal inflammation, reducing oxidative stress, and even slowing biological aging — all of which reflect in the skin.
Less Inflammation = Better Skin
One of the biggest ways omega-3 fatty acids support skin is by blunting the body’s chronic inflammatory response. A 2021 study found that middle-aged adults who supplemented with omega-3s for 4 months had lower cortisol spikes under stress and reduced levels of inflammatory cytokines like IL-6 — two major players in premature aging.
Other research has linked omega-3s to telomere preservation and a slower rate of epigenetic aging, both markers of long-term cellular health. That means the benefits go deeper than skin — but they definitely show on the surface.
Skin Benefits in Practice
- Calmer Skin: Omega-3s may help soothe reactive or redness-prone skin by reducing systemic inflammation.
- Fewer Breakouts: Some dermatologists use omega-3s as part of acne and eczema protocols to reduce flare-ups.
- Stronger Skin Barrier: Omega-3s support lipid layers in the skin, helping it retain moisture and defend against irritants.
In combination with antioxidants like vitamins C and E, omega-3s may even help protect against photoaging caused by UV exposure. A 2022 review confirmed that diets rich in omega-3s and antioxidants improve skin integrity and reduce signs of environmental aging.
How to Use Them
Most benefits are seen with daily intake over 2–4 months. Look for fish oil or algae oil supplements that contain EPA and DHA. If you eat a lot of cold-water fish (like salmon or sardines), you may already be covered. But for many, a supplement ensures consistent levels.

The Takeaway
Omega-3s won’t erase wrinkles overnight, but they build a foundation for healthier, calmer, more resilient skin over time. By tackling the internal fire of inflammation, they support aging well — inside and out.
Coming next: In the final article of this series, we’ll step back and look at the bigger picture — connecting omega-3s with collagen, ceramides, antioxidants, and more. Because the real magic happens when these ingredients aren’t used in isolation, but in harmony — inside and out.
