The influence of g-linolenic acid and honokiol on skin functions
Abstract
The diet and related supply of unsaturated fatty acids play an important role in the pathogenesis of diet-related disorders. γ-linolenic acid (GLA) is an omega-6 polyunsaturated fatty acid that has important biological functions in the human body, being an indispensable substrate for the production of eicosanoids. It is also one of the components of cell membranes, which is additionally involved in the processes of cholesterol transport and oxidation. The results of recent studies on the beneficial effects of GLA supplementation are very promising, including dermatological diseases. They support the hypothesis that GLA is an essential fatty acid for the normal function of the skin, which itself is unable to synthesise it. GLA deficiencies were found in many chronic skin diseases, such as: atopic dermatitis, psoriasis and eczema. Therefore, the preservation of the optimal structure and function of the skin largely depends on the exogenously supplied GLA. The rich source of this acid are vegetable oils commonly used in folk medicine. In addition, honokiol traditionally used in eastern medicine has a pleiotropic effect also in chronic dermatological diseases, not only because of its anti-inflammatory or antioxidant properties, but also because of its neuroprotective effect. Honokiol, by mild anxiolytic and antidepressant effects, improves the mood and increases the quality of life in patients with dermatological problems.
