Omega-3 EFA (essential fatty acids) plays a primary role in cell rejuvenation and basic overall human health; however, they can't be produced by the body. As such, the fatty acids must be obtained from food and nutritional supplementation. Found mainly in seafood such as anchovies and salmon, Omega-3 fatty acids are also present in avocados, green leafy vegetables, soy and nuts. Not only do they reduce the risk of heart disease, cancer, and allergies, the fatty acids also improve your skin and prevent UV damage. Fish oil capsules are one of the easiest ways to supplement your diet with omega-3 fatty acids.
Alleviates Skin Ailments
By adding omega-3 fatty acids to your diet either in pill form or by dietary means, you can ameliorate many dry skin conditions such as dermatitis, psoriasis and eczema. A condition called phrynoderma, which results in rough skin on the arms, thighs and buttocks, is caused by a deficiency of omega-3s in the diet.
An anti-inflammatory agent, omega-3 fatty acids reduce the incidence of dry skin conditions and the associated flaking and scaling. Fish oil contains polyunsaturated fats that help rejuvenate and replace cells and fats in the skin.
Treats Allergies and Hives
Omega-3s' anti-inflammatory properties are also useful in eradicating allergies, rashes and hives. The two main ingredients in omega-3 fish oils--EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid)--create prostaglandins or special hormones that help regulate cells in the body. These prostaglandins keep the hormone androgen in balance, providing immunity against external contaminants and pollutants that lead to allergies.
Remedy for Acne
Omega-3 is also a good remedy for skin imperfections such as pimples. EPA and DHA in fish oil produce the prostaglandins necessary to keep the hormone androgen in balance. As a result, androgen reduces the manufacture of sebum or oil in the hair follicles where pimples originate and prevents of occurrence of acne as well.
Protects Skin and Reduces Wrinkles
Omega-3s in the diet also protect the skin from UV harm because they boost the production of collagen and elastin which are needed to keep the skin moist and youthful looking. A 2005 study in the Journal of Lipid Research found that fish oil was helpful in the prevention of aging. Cells receiving omega-3s were also found to be more resistant to UV damage and wrinkles.
