Acne, the most prevalent skin disorder in the United States, affects about 40 million to 50 million Americans, according to the American Academy of Dermatology. Over-the-counter topical remedies containing benzoyl peroxide or salicylic acid are usually the first defense against acne. But some foods and supplements, such as cod liver oil, may also be beneficial. However, there are dangers linked to this supplement, so consult your doctor first.
What Is Acne?
Acne is a skin condition that causes blemishes or pimples to develop on your skin, especially your face, neck, shoulders, back and upper arms. The three main causes of acne include excessive oiliness in your skin, clogged pores or follicles and activity of the bacteria Propionibacterium acnes, or P. acnes, inside the clogged pores. The most effective way to treat acne is to tackle as many of the causes as possible.
Cod Liver Oil and Inflammation
When the P. acnes bacteria start to feed on the oil and dead skin cells in the clogged pores, inflammation develops, which leads to formation of pimples. Inflammation can be mild and superficial, or it can go deep into the skin, which causes cystic acne. Inflammation also increases oil gland production. Cod liver oil is rich in omega-3 essential fatty acids, which are potent anti-inflammatories that can help to reduce inflammation in your body.
Vitamin A in Cod Liver
Cod liver oil is a concentrated source of vitamin A. This nutrient helps to keep skin healthy and is an ingredient in common topical acne remedies, such as tretinoin. They treat acne by increasing skin cell turnover and preventing follicles from becoming clogged. Another vitamin A treatment for acne is isotretinoin, which you take orally under the care of a physician. Isotretinoin is the only known cure for acne, but it can cause serious side effects such as liver damage.
Risks of Using Cod Liver for Acne
Because of its high levels of vitamin A, cod liver oil may be toxic and cause liver damage when taken for a prolonged period or in high doses. Some people also experience nausea or allergic reactions such as itching, hives or tingling in their mouths or throats. Other allergic responses include difficulty breathing, chest tightness, or swelling in your face or hands. Consult your doctor before taking cod liver oil to treat acne, especially if you are pregnant, breast-feeding, or have a medical condition such as a liver disorder, bleeding disorder, heart disease or kidney stones.
