Photodynamic therapy

Abstract

Photodynamic therapy (or PDT) undoubtedly represents one of the most innovative, modern and technologically advanced dermatological therapies currently available. Initially introduced for the treatment of precancerous lesions and for skin tumors deriving from the epidermis (and therefore not melanocytic), photodynamic therapy has been used to treat an increasingly broad spectrum of skin conditions, both pathological and aesthetic (the so-called photorejuvenation). Based on the use of a sensitizing agent, PDT uses a particular light source to obtain its therapeutic and cosmetic effects. From light, therefore, the cause of thesetypes of injuries and skin aging, science has developed a technique that, through light itself, brings health and beauty to the skin.
