High levels of omega-3 fatty acids have been shown to decrease inflammation, and may reduce the risk of acne and other skin problems by decreasing insulin-like growth factor (IGF-1) and preventing hyperkeratinization of sebaceous follicles. Conditions such as atopic dermatitis and psoriasis have been shown to be positively affected by supplementation with omega-3s from fish oil, likely due to competitive inhibition of arachidonic acid leading to a reduction in the inflammatory process. Clinical results from omega-3 supplementation include an improvement in overall skin condition as well as a reduction in pruritis, scaling, and erythema. Omega-3 fatty acids have also been demonstrated to inhibit inflammation in the skin caused by UV radiation, and may even reduce the risk of skin cancer. Consuming foods rich in omega-3 fatty acids may lead to smoother, younger-looking skin with a visible reduction in inflammatory skin conditions like acne and psoriasis. These fats are especially abundant in cold water fatty fish such as sardines, salmon, mackerel, tuna, anchovies, and black cod, among many others.
