Fish oil is derived from omega-3-rich oils such as mackerel and herring. Although not all experts agree, some studies show that fish oil can help people with some skin conditions.

Omega-3 is a polyunsaturated fatty acid, which is a nutrient that the body cannot produce on its own.

In this article, we will look at this oil for skin, including its possible benefits, scientific findings, and the skin conditions it can help treat. We’ll even go into how to get the best out of fish oil.

Is fish oil good for the skin?

According to a 2018 study published in the Journal of Marine Medicines, fish oil and its elements, including omega-3, will help improve overall skin health. Based on the current study, this oil will benefit by:

  1. Maintain equilibrium
  2. Reducing inflammation, especially from UV rays
  3. Encourage skin regeneration

Scientists agree that the PUFAs in fish oil, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are responsible for these benefits (DHA).

Dietary fatty acids are incorporated into cell membranes by the body. The cell will contain water while the cell membrane is intact. This causes the skin’s cells to be hydrated and soft. Omega-3 fatty acids also aid in the reduction of inflammatory compounds that lead to ageing.

Other nutrients contained in fish oils include vitamin A, vitamin D, and selenium. Vitamin A is an antioxidant related to retinol and is widely used in personal care products and therapies for skin disorders.

Although there is evidence tha this oil improves overall skin wellbeing, literature on its benefits for particular skin disorders is more mixed.


Dry skin and eczema

Eczema, also known as atopic dermatitis, is a chronic inflammatory skin disease. They cause scratching and scaling, and the skin can crack and bleed at times. According to a 2013 study, both EPA and DHA may reduce inflammation, which can be beneficial to the skin. Other animal studies suggest that fish oil can help with eczema symptoms. A 2015 research in mice, for example, discovered that supplementation decreased itching-related dryness and scratching.

Ses findings, however, do not actually imply that this oil is an appropriate therapy for eczema in humans. According to a 2016 study, there is only insufficient evidence to support this function.

Scientists need to do further experiments of a larger sample size to fully appreciate the benefits of using this oil to treat eczema.



Acne pimples and cysts that are inflamed and sore are caused by it. As a result, the omega-3 content of fish oil can help to reduce overall inflammation in the body. However, experiments focused on the effects of this oil for acne have shown conflicting findings.

Over a 10-week timeframe, a brief, randomized, double-blind, controlled study discovered that omega-3 supplementation dramatically decreased acne lesions.

In comparison, research into lipids in health and illness has shown conflicting findings. While the majority of research participants saw an increase in their acne, others saw a deterioration of their symptoms.

Fish oil may help reduce acne in some individuals, but there is currently no strong evidence that it will help everyone.



Hyperpigmentation refers to dark patches on the skin caused by a spike in melanin production. Hyperpigmentation can be caused by a variety of factors, including:

  1. Hormonal shifts
  2. Ultraviolet ray exposure
  3. The aging process
  4. skin damage
  5. Medicines that cause photosensitivity

Fish oil can assist with hyperpigmentation in a variety of ways. Omega-3 fatty acids have been shown to suppress wound infections and speed up healing, which is beneficial in cases of traumatic hyperpigmentation.

DHA may also inhibit melanin formation, which could reduce the chance of hyperpigmentation caused by UV rays.

Can fish oil cause skin problems?

While uncommon, this oil can cause allergic reactions in people who are allergic to fish or shellfish. Headache, wheezing, and diarrhea are also possible symptoms.

It is important to note that a person who has a fish or shellfish allergy that interacts with fish oil can develop eczema. People who already have eczema can notice that their symptoms worsen.

If a person experiences signs of a serious allergic reaction to this oil, such as trouble breathing, they should seek medical attention right away.


How to use fish oil

People use fish oil in a variety of ways, but the most common is to take a fish oil supplement. Since fish oil has a strong taste and odor, it is not necessarily safe to use topically. The capsules aid in the absorption of this oil.

There are no clear dose guidelines for fish oil. However, the minimum dietary intake (RDI) for EPA and DHA is approximately 250 milligrams (mg).

The amount of EPA and DHA in this oils vary greatly, but people usually get 180 mg of EPA and 120 mg of DHA per 1,000 mg of fish oil.

According to a 2019 study, it is advisable to take a this oil supplement with a meal that includes certain dietary fats, since this increases omega-3 fatty acid bioavailability.

According to some studies, consuming this oil before a meal can help mitigate possible side effects including acid reflux and indigestion. However, another analysis found no discernible distinction. As for every dietary supplement, it is best to consult with your healthcare provider before beginning use.
