Role of Polyphenols in Dermatological Diseases: Exploring Pharmacotherapeutic Mechanisms and Clinical Implications.

Although not frequently lethal, dermatological diseases represent a common cause of consultation worldwide. Due to the natural and non-invasive approach of phytotherapy, research for novel alternatives, such as polyphenols, to treat skin disorders is a subject of interest in modern medicine. Polyphenols, in particular, have been considered because of their anti-inflammatory, antitumoral, antimicrobial, and antioxidant properties, low molecular weight, and lipophilic nature that enables the passage of these compounds through the skin barrier. This review discusses the treatment of common dermatological diseases such as acne vulgaris, fungal infections, dermatitis, alopecia, and skin cancer, using polyphenols as therapeutic and prophylactic options. The specific molecules considered for each disorder, mechanisms of action, current clinical trials, and proposed applications are also reviewed.
