Borage seed oil is highly valued for its exceptionally high concentration of gamma-linolenic acid (GLA), a fatty acid with potent anti-inflammatory properties, making it effective for soothing skin conditions like eczema, acne, and rosacea, as well as reducing joint inflammation in rheumatoid arthritis. It is also used topically as a, lightweight, non-greasy moisturizer to improve skin barrier function, reduce redness, and combat signs of aging.
