Essential fatty acids (EFAs) protect skin cell membranes by forming a barrier that prevents moisture from quickly evaporating. As you age, the loss of EFAs affects the structure of your skin cells, resulting in thinner, drier, more wrinkled skin.
Your body can synthesize most of the fats it needs from the food you eat. However, two essential fatty acids-linolenic and linolei-cannot be produced in the body and must be obtained from food. Linolenic acid is an essential omega-3 fatty acid found in seeds (notably chia and flaxseed), nuts (especially walnuts), and many common vegetable oils. Linoleic acid is a polyunsaturated omega-6 fatty acid that is abundant in many vegetable oils, especially safflower, sunflower, and corn oils.
Linolenic acid is the essential fatty acid most beneficial to your skin, whether in your diet or your skin care products. Dermatologist Nicholas V. Perricone, MD, reports in his best-selling book, The Wrinkle Cure, that foods rich in omega-3 fatty acids help reduce the body's production of inflammatory compounds-chemicals involved in the aging process that affect how healthy the skin looks and feels.
Essential fatty acids in skin care products are also anti-inflammatory while providing moisture to the skin, says Manhattan dermatologist and assistant professor at Mount Sinai School of Medicine, Debra Jaliman, MD. "EFAs are good for people with very dry skin, for example, those prone to eczema. Because EFAs have been shown to have an anti-inflammatory effect, anyone who is prone to allergies or
redness will benefit from EFAs."
