Photodynamic therapy is a method for the treatment of certain skin lesions. It consists of the application of a photosensitizing cream on the area of the skin to be treated and its subsequent irradiation with a dose of light red light. This technique causes a photochemical reaction that destroys atypical or altered cells without injuring those that are healthy. Among its many applications, photodynamic therapy is used for the treatment of: rosacea and certain types of acne; some types of skin cancer, such as basal or squamous carcinoma; fine wrinkles and aged skin; sun damage; scars; among others. Thanks to the photodynamic therapy it is possible to increase the oxygenation, brightness and smoothness of the skin, as well as repairing the skin lesions and eliminating the toxins.
