3 Ways Fish Oil Can Be Good For Your Skin

Fish oil is filled with omega-3 – a polyunsaturated fatty acid (or “PUFA”) that provides many health benefits. Believe it or not, omega-3 can help with skin care – so continue reading to discover 3 ways fish oil can help make your skin more radiant. (Plus, you'll discover how EverlyWell's Omega-3 Plus Test can help you see if you're getting enough of this potent nutrient.)

(1) It Provides Sunburn Protection

UV radiation from sunlight can damage your skin and result in a sunburn, which can increase your risk of skin cancer.

Consuming omega-3, however, can protect skin from sunburn. In one study, participants who took 10 grams of fish oil a day – for up to 6 months – increased their resistance to sunburn the longer they took the fish oil supplement [1].

In another study, participants supplementing with 4 grams of omega-3 per day (for three months) didn’t sunburn as easily compared to those who took another kind of unsaturated fatty acid: oleic acid (which can be found in avocados, olive oil, beef tallow, and other vegetable and animal fats and oils) [2]. This suggests that sunburn protection is a relatively unique effect of omega-3, and is not something that all unsaturated fatty acids have in common.

If omega-3 can help prevent sunburns , then can it also reduce skin cancer risk? Some research indicates that, yes, it can – linking higher consumption of omega-3 with a lower risk of developing some types of skin cancer [3].

(2) It Can Reduce Eczema Severity

Omega-3 fatty acids may help reduce the severity of chronic skin conditions like eczema. Research published in 2008, for example, found that daily doses of 5.4 grams of omega-3 lowered eczema severity by about 23% – at the end of 8 weeks [4]. (Eczema severity is quantified with a scoring tool known as SCORAD.)

Interestingly, some experts believe eczema is quite common in the United States largely because Western diets tend to have a less-than-ideal ratio of omega-6 to omega-3 [5].

What is the omega-6 and omega-3 ratio?

Omega-3 is not the only polyunsaturated fatty acid. There are other types of polyunsaturated fatty acids, one of which is omega-6. Omega-6 is commonly found in corn oil, cottonseed, safflower, soybean, and sunflower oil – as well as red meat and poultry. The amount of omega-6 in your body compared to the amount of omega-3 is the omega-6:omega-3 ratio.

In general, you want a low omega-6:omega-3 ratio because high amounts of omega-6 – relative to omega-3 – can contribute to a variety of health problems (such as inflammation). The majority of people in the United States, however, have a high omega-6:omega-3 ratio.

(3) It Can Help with Acne Management

There are a number of compelling clues that omega-3 can have a positive effect on acne. For example, a number of studies show that acne occurs less often in communities whose diets are rich in omega-3 [6].

Other research studies have explored more direct links between omega-3 and acne. In a 10 week trial, individuals who took 2 grams of omega-3 per day witnessed nearly a 30% drop in acne severity compared to the control group (based on the Cunliffe grading system for acne severity) [7].

Why might fish oil have this effect on acne? No one knows for sure, but some researchers think it’s because omega-3 fatty acids can block the formation of inflammatory compounds involved in acne [8]. So, now you know: omega-3s can help with inflammation in the skin.

How You Can Make Sure You’re Getting Enough Omega-3

If you want to make sure you’re getting enough omega-3 from your diet, try to eat oily fish – like salmon, tuna, and sardines – at least twice a week [9].

Testing your omega-3 levels is another important step you can take. You can do that from the comfort of home with EverlyWell’s Omega-3 Plus Test. This test reveals your overall omega-3 status, as well as your omega-6 to omega-3 ratio. It thus gives you key information about your wellness – alerting you to deficiencies in omega-3 and showing how high your omega-6:omega-3 ratio is.

Omega3Plus Make sure you’re getting enough omega-3 from your diet with EverlyWell's Omega-3 Plus Test.

Here’s how one test-taker explained the value of taking EverlyWell’s Omega-3 Plus kit:

“This test was super easy to use, and I found out that my ratios were very off. The information was detailed and easy to read, plus had valuable content for how I can change my diet to improve my ratios.”


Omega-3 can benefit your skin by preventing sunburns and reducing eczema and acne severity, according to a number of scientific studies. To make sure you’re getting enough omega-3 to support your skin’s well-being, simply take EverlyWell’s Omega-3 Plus Test.
