Photodynamic Therapy with ALA

Levulan® Kerastick® or ALA (aminolevulinic acid HCl) for Topical Solution, 20% (Levulan Kerastick) plus blue light illumination using the BLU-U® Blue Light Photodynamic Therapy Illuminator (Levulan PDT) is indicated for the treatment of minimally to moderately thick actinic keratosis of the face or scalp. Actinic keratosis (AKs), are rough-textured, dry, scaly patches on the skin that can lead to skin cancer.

PDT with ALA, a two-part treatment, is unique, because it uses a light activated drug therapy to destroy AKs. How does it work? Levulan Kerastick Topical Solution is applied to the full area of concern. The solution is then absorbed by the AK cells where it is converted to a chemical that makes the cells extremely sensitive to light. When the AK cells are exposed to the BLU-U Blue Light Illuminator or Broad Band Light, a reaction occurs which destroys the AK cells. It is important to treat AKs because there is no way to tell when or which lesions will progress to squamous cell carcinoma (SCC), the second most common form of skin cancer. Now’s the time to manage your damage!
