Photodynamic Therapy: State-of-the-Art Treatment for Precancers
Photodynamic therapy is one of the most exciting advancements in dermatology in the last 15 years. It is used to treat precancers and actinic damage over the entire face, scalp, chest or forearms. A solution is applied to the area and allowed to penetrate for a prescribed amount of time. Then a blue light is used to activate the solution which then “attacks” the precancerous cells. The result is a sunburn-like reaction lasting on average 4 to 6 days. Not only are precancerous lesions treated leading to a decreased chance of skin cancer, but also the entire area is rejuvenated, smoother and less photodamaged.. Typically, at least two treatments are needed for the best results and can be repeated periodically to maintain results.
Photodynamic Therapy for Acne and Rosacea
Photodynamic therapy has also been shown to reduce the appearance of acne rosacea and acne vulgaris. It is effective in treating mild and moderate acne by reducing the amount of oil that sebaceous glands are able to produce. Clinical studies have shown that 50-60% of patients with moderate to severe acne have achieved and maintained clearance for up to 1 year with 3 treatments. Usually 3-6 treatments are recommended for the treatment of acne. Results may vary amongst patients. Some patients may see clearance for longer periods of time while others may take longer to see improvement. Blue light treatment without the addition of Levulan is also an option for females who are pregnant and experiencing acne, as many prescription products for acne are to be avoided during pregnancy and breastfeeding.
