Precancerous Treatments – Photodynamic Therapy (PDT)
Precancerous treatments such as Photodynamic therapy (PDT) use special drugs, called photosensitizing agents, along with intense light to kill precancerous and cancerous cells. When a photosensitizer like Levulan® Kerastick® is exposed to a specific wavelength of light, they produce a form of oxygen that kills nearby cells. Blu-U® Blue Light Photodynamic Therapy can help clear the skin of actinic keratoses which are premalignant growths in sun-exposed areas, mainly the face, chest, arms and hands. It is also effective for moderate to severe acne.
