ABSTRACT
The importance of supplementation in dermatology: Facts and myths about collagen, zinc and omega-3 acids
The growing popularity of dietary supplements for improving the condition of skin, hair, and nails means that dermatologists have to increasingly often deal with questions from patients about the effectiveness of such products. Supplements containing collagen, zinc, and omega-3 fatty acids are particularly popular. Although their beneficial effects are widely promoted in marketing, the level of scientific evidence remains variable. As far as collagen is concerned, available studies indicate the possibility of moderate improvements in skin hydration and elasticity, but the quality of some data raises methodological concerns. Zinc plays a significant role in wound healing, immune response, and the functioning of the epidermal barrier, and its supplementation is primarily justified in zinc deficiency states and for selected diseases. Omega-3 fatty acids have anti-inflammatory effects and may support the treatment of some inflammatory dermatoses, although their effectiveness depends on the type of condition and the dose used. The aim of this paper is to present the current state of knowledge regarding the use of dietary supplements in dermatology and to separate facts from common myths.
