The website of the dermalologist i am seeing for laser treatment talks about using red light and ALA cream to treat skin cancers.
A bit different from using red light for rosacea obviously, but interesting that it says that there are no complications, because believe me the sections on IPL and laser list many possible complications.
ALA-PDT – PHOTODYNAMIC THERAPY TREATMENT.
Skin Cancer affects half of the population in Australia at some point in their lifetime. The main cause is exposure to sunlight and the harmful ultraviolet rays that sunlight contains. Such skin conditions caused by the sun’s damaging rays may be treated with a new technique – Photodynamic Therapy (PDT) which uses a pure red light to treat the affected skin.
PDT is not a complicated procedure and usually requires one treatment. The treatment consists of the application of a special cream (5-ALA) directly to the skin cancer. The creams remains on for 4-6 hours at which time the area is exposed to a pure red light source. After the treatment a special dressing is applied to the area and you are able to go home.
The treatment is simple and does not harm normal skin. There have been no noted complications during the treatment and no long term side effects. Healing is rapid and the final quality of healing is usually excellent with a good cosmetic result. One treatment is all that is usually necessary but occasionally a second treatment may be required.
