Omega-3s play an important role in maintaining skin health and appearance. Documentation shows that omega-3s not only play a role in both the dermal (internal) and epidermal (external) layers of the skin, but they also play a role in the appearance of the skin, linking to the functional health of the skin as well.
Omega-3s and the Layers of the Skin
The skin is organized into two main layers: the outer layer called the epidermis, and the middle layer of skin directly beneath the epidermis called the dermis. The epidermis keeps your body hydrated, produces new skin cells, and contains melanin, which determines the color of your skin. The dermis supports your epidermis, produces sweat and hair, on top of many other things.
What does this have to do with Omega-3s? Omega-3s, EPA and DHA, are a natural part of the epidermal barrier; they help keep the skin strong so that water and nutrients can remain on the surface providing a nourishing protective seal, closing the path for bacteria to enter. In addition, they are a crucial part of your skin’s lipid (oily) content. When this oil layer of the skin is compromised, moisture escapes and skin may become dry and rough. Omega-3 benefits for skin include helping to improve skin hydration, elasticity, and firmness, may minimize collagen adversity associated with the process of skin aging, and are beneficial in protecting skin from UV rays.
The Key to Silky Hair
For the same reasons, EPA and DHA also have hair benefits. Each pore on the surface of your scalp has an opening to a canal called a follicle. This follicle contains a hair and an oil gland. EPA and DHA are essential for these oil glands to provide the healthy oils to nourish hair follicles and to help prevent dryness.
