Cod Liver Oil Benefits for The Skin
Tip
There’s no definitive evidence that cod liver oil benefits the skin. Instead, talk to your dermatologist about a topical treatment for acne, psoriasis, scarring and dry skin.
What Is Cod Liver Oil?
Cod liver oil is exactly what it sounds like — oil taken from the livers of cod fish. This dietary supplement, available in liquid and capsule forms, provides vitamin A, vitamin D and omega-3 fatty acids. Cod liver oil is particularly rich in the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Dosage of these nutrients varies from brand to brand.
One serving of Nordic Naturals Arctic Cod Liver Oil capsules provides 25 calories, 3 grams of fat, 10 milligrams of cholesterol, 30 micrograms of RAE vitamin A, 240 milligrams of EPA, 360 milligrams of DHA and 150 milligrams of other omega-3s.
One serving of 21st Century Norwegian Cod Liver Oil provides 375 micrograms of vitamin A, 3 micrograms of vitamin D3, 28 milligrams of EPA and 24 milligrams of DHA.
Cod Liver Oil and Skin
Some cod liver oil capsules contain vitamin A and vitamin D. Both of these vitamins have uses for skin health when applied as topical creams or ointments rather than taken as a dietary supplement. You may have read anecdotal accounts that taking cod liver oil benefits your skin, but the evidence for this is limited.
Topical vitamin D can be used to treat psoriasis and dry or itchy skin. Vitamin A and its derived compounds are known as retinoids, and these substances are common topical skin treatments for acne. According to the Linus Pauling Institute at Oregon State University, topical retinoids can also reduce signs of photoaging like wrinkles and fine lines.
Cod Liver Oil for Acne
There's little reliable evidence that taking dietary supplements of cod liver oil improves acne. Plus, research on fish oil for skin more generally has been inconclusive. Available studies on the topic are often small and outdated.
The Mayo Clinic acknowledges that taking fish oil is a potential alternative medicine treatment for acne, along with other treatments like topical tea tree oil, brewer's yeast and oral zinc supplements. According to the clinic, further research is necessary to establish whether these alternative treatments are effective and safe in the long term.
Effective Acne Treatments
Acne is caused by inflammation of the hair follicles and oil-producing glands in your skin called sebaceous glands. Harvard Health explains that when sebaceous glands are overstimulated, hair follicles get blocked by oil and skin cells that haven't shed. Bacteria inside the blocked hair follicle then multiplies.
There are various ways acne can present, including:
- Whiteheads, which are closed plugged pores
- Blackheads, which are open plugged pores
- Papules, small bumps that may be red or tender to the touch
- Pustules, which are papules that have pus at their tips
Instead of using cod liver oil for acne, try recommended treatments like topical retinoids and antibiotics. Retinoids prevent your hair follicles from clogging, while antibiotics kill excess skin bacteria. Another option is salicylic acid, which may also prevent hair follicles from clogging.
Other Skin Therapies
If medication is not the right option for you, a dermatologist may recommend a skin therapy to treat whatever issue you're dealing with. However, always research a skin therapy provider before having any procedures done.
A chemical peel removes the damaged outer layers of your skin. This can make your skin look softer and brighter and in some cases can improve skin texture. Some cosmetic peels can improve the appearance of scarring, including pitted scars from acne.
