Is fish oil good for the skin?

Date

We at ProSana know that a lot of people have problems with certain skin conditions. We support the content in this article written by –  Medical News Today.

Fish oil is an excellent source of omega 3 fatty acids. Omega-3 is a polyunsaturated
fatty acid, which is a type of nutrient that the body cannot make for itself. Some
research suggests that these fatty acids can improve skin health, as well as specific
skin conditions, such as eczema and acne.


Fish oil comes from fish that are rich in omega 3, such as mackerel and herring. Some
studies suggest that fish oil may benefit people with certain skin conditions, though not all
researchers agree. Scientists need to perform more research to understand exactly how
effective fish oil is for treating skin conditions, as some studies have had mixed results. It is
not entirely clear whether taking a fish oil supplement will be beneficial for everyone.
However, some people notice an improvement in skin hydration and overall skin health,
which may alleviate certain skin conditions.


Is fish oil good for the skin?
A 2018 review in Marine Drugs notes that fish oil and its components, including omega-3, can help support the skin’s overall health. The review found evidence that fish oil can help by:
• Maintaining homeostasis
• Improving barrier function
• Inhibiting inflammation, particularly from UV light
• Promoting skin healing


Scientists believe that these benefits are due to the PUFAs in fish oil, which include
eicosatetraenoic acid (EPA) and docosahexaenoic acid (DHA).
The body incorporates dietary fatty acids into cell membranes. When a cell membrane is
healthy, the cell can hold water. In the skin, this results in cells being hydrated and soft.
Omega-3 fatty acids also helped the production of inflammatory compounds that contribute
to the aging process.

Some fish oils contain other nutrients, such as vitamin A, vitamin D, and selenium. Vitamin A
is an antioxidant related to retinol, a popular ingredient in skin care products and a treatment
for skin disorders.
However, while evidence supports the idea that fish oil boosts general skin health, the
research on its benefits for specific skin conditions is more mixed.

Dry skin and eczema

Eczema, or atopic dermatitis, is an inflammatory condition of the skin. It causes itching and
scaling, and the skin can sometimes crack and bleed.
A 2013 research notes that both EPA and DHA can inhibit inflammation, which may benefit
the skin. Other studies on animals also show that fish oil may lessen eczema symptoms. For
example, a 2015 study on rats found that supplementation reduced itch-related scratching
and dryness.
However, scientists need to carry out more studies involving a larger number of people to
understand the value of using fish oil to alleviate eczema.

Acne
Acne causes pimples and cysts, which can be inflamed and painful. For this reason, the
omega 3 content in fish oil may be helpful for reducing general inflammation in the body.
However, studies that focus on fish oil’s benefits for acne specifically have mixed results. A
small randomized, double-blind, and controlled trial found that omega-3
supplementation decreased acne lesions significantly over the course of 10 weeks.
Fish oil may help reduce acne in some individuals, but there is currently no strong evidence
that it will help everyone.

Hyperpigmentation
Hyperpigmentation describes darker patches of skin that occur because of increased
melanin production. There are many causes of hyperpigmentation, including:
• Hormonal changes
• UV exposure
• Aging
• Skin trauma
• Medications that cause sunlight sensitivity
Fish oil could potentially help reduce hyperpigmentation in several ways. Omega-3 may
minimize wound infections and speed up healing, which is useful in cases of
hyperpigmentation that are due to skin trauma. DHA can also inhibit melanin production,
which may reduce the risk of UV-induced hyperpigmentation.

How to use fish oil
The Norwegian health authorities recommend eating fish 2-3 times a week. Taking cod liver
oil / or an omega 3 product as a dietary supplement might be a good alternative to secure a
daily sufficient intake of fatty acids.
