How Effective is Photodynamic Therapy

Photodynamic therapy is highly effective in treating sun spots, and some skin cancers with a cure rate of over 80%. In the treatment of sun damage and aging, the cosmetic improvement is significant. Skin texture and colour usually are substantially improved, and many brown blemishes disappear. PDT is useful in the treatment of acne, and can be used in conjunction with other acne therapies. Several treatment sessions are usually needed.

What sort of light is used?

The ALA cream is activated by many different light and laser sources. Pulsed light (IPL), Blue and Red light are commonly used. These are not ultraviolet lights, so do not cause skin cancers. These light sources are not X rays so are not harmful to your body or your skin. Many studies have shown that PDT may help to prevent skin cancers. When PDT is combined with Pulsed Light (IPL) there is significant rejuvenation of the skin, and reduction of red veins and brown marks.

During the treatment a cream is applied to the skin for about 1 hour and then the skin is exposed to either a Blue, Red or Pulsed yellow light. The cream is selectively taken up by the abnormal skin cells. The cream within the cells is then activated by the light leading to removal of abnormal cells.
