Actinic Keratosis-PDT

What are Actinic Keratosis?

Actinic keratosis are rough scaly patches on the skin caused by chronic sun exposure. They are more common in fair skin/blue-eyed people and are precancerous. If left untreated, actinic keratosis may progress to squamous cell skin cancer. Therefore, early treatment of actinic keratosis will reduce the risk of developing skin cancer. Treatments for Actinic Keratosis include: Fluorouracil, Imiquimod, Picato, Diclofenac, Liquid nitrogen, and PDT.


What is Photodynamic Therapy (PDT) ?

PDT is an FDA approved treatment for actinic keratosis. It works through the topical application of a photo sensitizing chemical (Levulan) which is then stimulated by a blue wavelength of light. The chemical reaction subsequently destroys actinic keratosis (i.e. precancerous lesions).
