Acne is a condition due to inflammation and the types of foods we eat influence the inflammatory process. In this 10-week study, 45 participants with mild to moderate acne, which were allocated to either an omega-3 fatty acid group (2,000 mg of eicosapentaenoic acid and docosahexaenoic acid), a γ-linoleic acid group (borage oil containing 400 mg γ-linoleic acid), or a control group. After 10 weeks of omega-3 fatty acid or γ-linoleic acid supplementation, inflammatory and non-inflammatory acne lesions decreased significantly. The researchers conclude that omega-3 fatty acid and γ-linoleic acid could be used as an additional treatment for acne patients. View a detailed list of foods that help with skin health or cause acne.
