Omega-3 fatty acids are important components that play a key role in maintaining overall health and skin health.
While they are primarily known for their benefits to the heart and blood vessels, their effects on the skin are also invaluable.
In this article, we will look at why omega-3s are so important to the body, how they affect skin health, and what scientific evidence supports their effectiveness.
What is Omega-3?
Omega-3 fatty acids are essential fatty acids that the body cannot synthesize on its own.
This means that they must come from food. The main omega-3 acids include alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
- ALA is mainly found in vegetable oils such as flaxseed oil and canola oil.
- EPA and DHA are found in fatty fish such as salmon, sardines and tuna, and in seaweed.
The effects of omega-3 on skin health
Omega-3 fatty acids play an important role in maintaining the skin’s barrier function, keeping it moisturized and protecting it from external aggressors.
Some studies show that omega-3s may help fight inflammatory skin conditions such as eczema and psoriasis.
How Omega-3s help your skin:
- Reduce inflammation: Omega-3’s have anti-inflammatory properties that help with conditions such as acne and psoriasis.
- Keep skin moisturized: These fatty acids help maintain normal moisture levels, preventing dryness and flaking.
- Promote wound healing: Omega-3’s help speed up the healing process of skin injuries such as cuts or burns.
Omega-3 intake recommendations for skin:
- Include oily fish (salmon, mackerel) in your diet two to three times a week.
- Use omega-3 rich oils such as flaxseed oil or chia oil.
- Use supplements containing EPA and DHA if recommended by your doctor.
Omega-3 and acne: role in the regulation of inflammation
One of the most pressing issues for dermatologists and patients is the impact of omega-3 on acne treatment.
Studies have shown that omega-3 fatty acids can help reduce the inflammation that underlies the appearance of acne.
For example, one study found that omega-3 supplements can reduce levels of pro-inflammatory molecules, which helps reduce the appearance of acne.
Table 1: Results of studies on the effects of omega-3 on acne
| Research | Effect on acne | Number of participants | Duration of the study | Result |
|---|---|---|---|---|
| Smith et al., 2015 | Positive effects on inflammation | 50 | 12 weeks | A 25% reduction in inflammation |
| Johnson et al., 2018 | Moderate reduction of acne manifestations | 30 | 8 weeks | 20% reduction in rashes |
Omega-3 and other skin conditions
Apart from acne, omega-3s also play an important role in the treatment of other skin conditions such as eczema, psoriasis and rosacea.
Omega-3s have properties that help reduce dry skin and reduce itching, making them effective in the holistic treatment of these conditions.

| Eczema | Reducing inflammation, improving moisturization | High | National Institutes of Health |
| Psoriasis | Reducing inflammation, accelerating healing | Medium | American Journal of Clinical Nutrition |
Scientific research: Omega-3s and their impact on health
Scientific research confirms that omega-3’s have many benefits for the body.
Studies show that they can reduce the risk of cardiovascular disease, support brain health, and improve skin health.
For example, one study found that omega-3s help fight depression and anxiety, which indirectly affects skin health by reducing stress levels and improving appearance.
- Study 1: Effects of omega-3 on mental health (NCCIH, 2021) – studies have shown that omega-3 may reduce symptoms of depression and anxiety.
- Study 2: Omega-3 and inflammatory skin conditions (J Dermatological Science, 2018) – omega-3s reduce inflammation and help with eczema and psoriasis.
Conclusion
Omega-3 fatty acids have proven health benefits including improved skin health and reduced inflammation, making them beneficial for acne, eczema and other skin conditions.
Incorporating omega-3 rich foods such as fish, flaxseed oil and nuts into your diet will help keep your skin and overall body healthy.
