Light is something that is part of everyone’s lives, but not many people know the many benefits that it has besides helping us see things in the dark. In fact, light can have several benefits in the field of dermatology and cosmetics. An example of it is the Photodynamic Therapy.
The Photodynamic Therapy, also known as PDT or Blue Light Therapy, is a non-invasive therapy that uses photo sensitizing molecules in combination with a light source that activates them. The combination of the light and the molecules destroy abnormal cells, leaving the healthy cells intact. This type of therapy is used to treat several conditions such as sun damage, acne, scars, rosacea and even pre-skin cancer lesions. But this treatment is not indicated for everyone. Although it can be used to treat pre-cancer lesions, PDT does not offer a cure for invasive skin cancer. In this case, more severe treatments are needed, such as radiotherapy or even surgery. The PDT is also not indicated for deep areas in the skin since it is more effective in lesions right below the surface of the skin.
A PDT session is quite a simple process. First, a solution of a photo sensitizing agent is applied to the area that will be treated. After 30 to 60 minutes, which is called “incubation period”, the same area is submitted to intense light. The whole process takes about one hour. Usually, the patient will need more than one session to complete the treatment. At the end of the treatment, you should expect a smoother and healthier looking skin.
This therapy is a safe procedure, but all procedures have possible side effects. In the case of PDT, some possible side effects are burning, skin discoloration, pain, allergic reactions, prolonged sun sensitivity and others. Although some skin irritation can occur, PDT doesn’t normally leave scars.
The PDT recovery is quite straightforward and usually doesn’t present many complications. We advise cleaning the area carefully to avoid infections. Sometimes antibiotic ointments and moisturizers are applied after the procedure. In case of swelling in the first days, ice can be used to relieve it. One of the most important measures to be taken is to protect the area with sunscreen.
