Omega 3 Fatty Acids… Why are they important for your skin?

By Dr. David Harvey, MD, FAAD, FACP

What are Omega 3 fatty acids?

Omega-3 fatty acids are considered essential fatty acids. They are essential to human health but cannot be manufactured by the body. For this reason, omega-3 fatty acids must be obtained from food. Omega-3 fatty acids can be found in fish, such as salmon, tuna, and halibut, certain plants (including purslane), nut oils, and the natural peruvian grain Salvia Hispanica (Fig. 1). Omega-3 fatty acids play a crucial role in brain function as well as normal growth and development.
