GLA has been shown to be very useful in preventing and treating inflammation and skin conditions such as eczema and dermatitis when applied topically.

GLA is said to be effective in treating transepidermal water loss and epidermal hyper-proliferation when GLA-enriched food was introduced to subjects' diet. In this study, GLA has demonstrated to be efficacious especially in subjects with pro-inflammatory characteristics.
