Acne isn't just a problem for teens, although 85% of teens and young adults contend with it. It affects adults too, popping up for the first time after the age of 25.

According to Yale Medicine, 25% of women and 12% of men in their 40s have acne.

You've probably heard that acne can be caused by hormone fluctuations, stress, or even a reaction to certain foods such as dairy.

However, a new study reveals another possible cause that makes sense to us: a deficiency of omega-3 fatty acids. That's because not getting enough omega-3s is associated with chronic inflammation that can wreak havoc in all parts of your body, including your skin.

A study published in the Journal of Cosmetic Dermatology enlisted 60 people with mild to moderate acne and found that more than 98% of them were deficient of omega-3s. But when the participants took 600 mg of DHA and 300 mg of EPA (two types of omega-3 fatty acids) daily for eight weeks, then 800 mg of DHA and 400 mg of EPA daily for eight more weeks — and adopted a Mediterranean diet — their skin lesions were reduced significantly.

The participants reported that increasing their intake of fruits, vegetables, and whole grains was most beneficial; as was reducing saturated fats, dairy, and alcohol.

Enjoy walnuts, chia seeds, wild salmon, and ocean trout — all of which are loaded with omega-3s — and consider combination EPA/DHA supplements.
