What is Photodynamic Therapy?
Photodynamic Therapy (PDT) treats acne and pre-cancerous sun damage, or actinic keratosis. It involves the application of Levulan®, a photosensitizing agent, and its activation under a medical-grade therapeutic blue light source (BLU-U®).
How does it work?
Levulan® is absorbed by the targeted cells and converted into a chemical that heightens their sensitivity to light — under the BLU-U® illumination, the targeted cells are destroyed.
BLU-U® blue light therapy is often used to address mild to moderate acne.
