An Underrated Supplement That Supports Skin Health (Besides Collagen)

While omega-3s are well-known for their heart- and brain-related benefits, they're actually great for the skin, too. While the research on skin specifically is still gaining, there have been notable findings. 

Firstly, omega-3 supplements have been shown to improve the severity of atopic dermatitis1, also known as eczema. Gamma linolenic acid (GLA), in particular, has also been shown to treat transepidermal water loss (TEWL) and support a hydrated and healthy skin barrier2. 

A 2020 review on omega-3 fatty acids in dermatology also concluded that this supplement can be helpful for many kinds of inflammatory skin conditions, including acne3.

Interestingly, oral omega-3 fatty acids via fish oil actually helped reduce side effects from isotretinoin treatment (formerly known as Accutane), including alleviating dryness4.

See, maintaining a healthy skin barrier is of vital importance when it comes to achieving even-toned, hydrated, and generally well-functioning skin. Most people tend to the skin barrier topically, but that's only half of the equation. Keeping your skin hydrated from within via adequate water intake; nutritious, water-dense foods; and skin-moisturizing supplements (hello, omega-3s!) completes that full puzzle. 

Even if hydration and inflammation control aren't your main skin care goals, this supplement is incredibly beneficial for other full-body effects. These include eye health and vision, mood, joint health, and so much more—omega-3 supplementation is far more than a beauty habit.
