Omega-3 and Acne: Can Omega-3 Fatty Acids Help Improve Your Skin?

Could omega-3 intake be affecting your acne? Omega-3 fatty acids are often discussed for heart health, brain health and inflammation, but many people also wonder whether they could support acne-prone skin. This makes sense because acne is not just a surface-level skin issue. It can involve inflammation, immune activity, oil production, skin healing, hormones, gut health and diet. The answer is not as simple as saying omega-3 “cures” acne. Research suggests omega-3 fatty acids may be helpful for some people, especially where inflammatory acne is present, but acne is rarely caused by one nutrient alone. This guide explains what omega-3 fatty acids are, why they may be relevant for acne, what the research says, food sources, supplement considerations and why a personalised approach matters.

What Are Omega-3 Fatty Acids?

Omega-3 fatty acids are essential fats, meaning the body cannot make enough of them on its own and they need to come from the diet. The main omega-3 fatty acids are:

• EPA — Eicosapentaenoic acid, found mainly in oily fish and algae.
• DHA — Docosahexaenoic acid, found mainly in oily fish and algae.
• ALA — Alpha-linolenic acid, found in plant foods such as flaxseeds, chia seeds and walnuts.

EPA and DHA are the forms most strongly associated with anti-inflammatory effects. ALA can be converted into EPA and DHA, but this conversion is usually limited. Omega-3 fatty acids support:

• Inflammation regulation
• Cell membrane health
• Skin barrier function
• Immune function
• Heart and brain health
• Hormone-related processes
• General wellbeing

Why Might Omega-3 Affect Acne?

Omega-3 may be relevant to acne because of its role in inflammation. Inflammatory acne can appear as red, swollen, painful spots, pustules, nodules or cysts. While blocked pores and oil production are part of the picture, inflammation often plays a major role in how angry or persistent breakouts become. Omega-3 fatty acids may support acne-prone skin by helping to regulate:

• Inflammatory pathways
• Immune responses within the skin
• Skin barrier function
• Cell membrane health
• Skin healing
• The balance between pro-inflammatory and anti-inflammatory fats

This does not mean everyone with acne needs fish oil supplements. It means omega-3 intake may be one factor worth exploring as part of a wider skin, diet and inflammation picture.

What Does the Research Say?

The research around omega-3 and acne is promising, but still developing. A small clinical study found that supplementation with omega-3 fatty acids or gamma-linolenic acid for 10 weeks was associated with reductions in inflammatory and non-inflammatory acne lesions. Read the omega-3 acne supplementation study. Another pilot study found that fish oil supplementation was associated with improvement in overall acne severity, especially in individuals with more inflammatory acne at baseline. Read the fish oil and inflammatory acne study. More recent research found that many acne patients had low omega-3 fatty acid levels, and that acne severity improved significantly in those who reached target omega-3 levels during the study. Read the omega-3 levels and acne study. A 2024 study also suggested omega-3 supplementation may reduce acne inflammation partly through effects on the gut microbiome and short-chain fatty acid pathways. Read the omega-3 and acne inflammation study. Overall, omega-3 may support inflammatory acne in some people, especially where intake is low. However, acne is usually influenced by multiple factors at once.

Can Low Omega-3 Intake Affect Acne?

Low omega-3 intake may contribute to a more inflammatory environment in the body, but this does not mean it directly causes acne for everyone. Many modern diets are relatively low in oily fish and higher in processed foods, refined oils and omega-6-rich foods. Omega-6 fats are not “bad”, but the overall balance between different types of fats may influence inflammatory pathways. Low omega-3 intake may be worth considering if you: These signs do not confirm an omega-3 deficiency, but they may suggest your fat intake and overall diet are worth reviewing.

Omega-3 Food Sources

Food should usually be the first place to start when thinking about omega-3 intake. The NHS advises eating at least two portions of fish per week, including one portion of oily fish. Read the NHS guidance on fish and shellfish.

Should You Take Omega-3 Supplements for Acne?

Omega-3 supplements may be useful for some people, especially where oily fish intake is low or where dietary intake is difficult to improve. However, supplements are not automatically the right choice for everyone. Omega-3 supplementation may need extra care if you:

• Take blood-thinning medication
• Have a bleeding disorder
• Are due to have surgery
• Are pregnant or breastfeeding
• Have a fish or shellfish allergy
• Already take multiple supplements
• Are unsure whether omega-3 is relevant to your skin

Quality also matters. Some fish oil supplements can become oxidised or may not provide the amount of EPA and DHA expected. If using supplements, it is important to choose a reputable product and consider whether it fits your wider health picture.

About Omega-3 and Hormonal Acne

Omega-3 may be relevant for hormone-related acne because inflammation, blood sugar balance and hormone signalling can all influence the skin. However, hormonal acne is rarely explained by one nutrient or one food alone. Jawline acne, chin acne, irregular cycles, PCOS, stress, blood sugar imbalance and gut symptoms may all provide useful clues about what is happening beneath the surface. If you suspect hormones are contributing to your acne, you may find it helpful to read Foods for Hormonal Acne and Acne and PCOS.

Could Gut Health Affect Omega-3 Status?

Omega-3 fatty acids are fats, which means digestion and absorption matter. If someone has ongoing gut symptoms such as bloating, diarrhoea, constipation, reflux, food sensitivities or poor fat digestion, it may be worth exploring whether digestive function is affecting nutrient absorption more broadly. Gut health may also influence acne through inflammation, immune regulation, the gut microbiome and the gut-skin axis. You can read more about this in Can Gut Health Cause Acne? and The Gut-Skin Axis.

Omega-3 Is Only One Piece of the Puzzle

Omega-3 fatty acids may support inflammation balance and skin health, but acne is rarely explained by one nutrient alone. For some people, omega-3 intake may be relevant. For others, the bigger drivers may be hormones, gut health, blood sugar balance, stress, sleep, skincare products, food triggers or other nutrient imbalances. You may also find it useful to read:

What This Means for You

Omega-3 may be worth considering if you have acne, especially if your intake of oily fish is low, your skin is inflamed, your diet is limited or you have signs of wider inflammation. However, the question is not simply: “Should I take omega-3 for acne?” The better question is: “Is omega-3 one of the factors that matters for my skin?” That is where a personalised approach can be valuable.

Frequently Asked Questions

Final Thoughts

Omega-3 fatty acids play an important role in inflammation regulation, cell membrane health, immune function and skin health. Research suggests omega-3 may support inflammatory acne in some people, especially where intake or omega-3 status is low. However, omega-3 is not a cure for acne, and it should not be viewed in isolation. If your acne is persistent, recurring or linked with digestive symptoms, hormone changes, stress, food sensitivities or fatigue, it may be time to look at the bigger picture.
