Findings

After 10 weeks, people taking omega-3 fatty acids (2,000 mg) or gamma-linolenic acid (400 mg from borage oil) saw significant decreases in both inflammatory and non-inflammatory acne lesions compared to placebo. Skin biopsies showed reduced inflammation and lower levels of interleukin-8, a protein that drives acne. No serious side effects were reported.
