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 PTD or Blue Light Therapy, is a non-invasive therapy that uses photosensitizing 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 to everyone. Although it can be used to treat pre-cancer lesions, PTD does not offer a cure for invasive skin cancer. In this case, more severe treatments are needed, such as radiotherapy or even surgery. The PTD is also not indicated to deep areas in the skin since it is more effective in lesions right below the surface of the skin.

A PTD session is a quite simple process. First, a solution of a photosensitizing 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 PTD, some possible side effects are burning, skin discoloration, pain, allergic reactions, prolonged sun sensitivity and others. Although some skin irritation can occur, PTD doesn’t normally leave scars.

The PTD recovery is quite straightforward and usually doesn’t present many complications. Physicians advise cleaning the area carefully to avoid infections, and they might even recommend antibiotic ointments and moisturizers. 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.

So if you have any of the following skin conditions such as sun damage, acne, scars, rosacea and even pre-skin cancer lesions, PTD may be able to reduce or eliminate them. Contact our office today to learn more!
