Dr. Rebecca Baxt and Dr. Saida Baxt have found Photodynamic Therapy to be an effective treatment of acne when used with a photosensitizing agent, such as Levulan®. This topical medication is carefully applied to the acne and allowed to settle into the skin. After a period of time, PDT or a laser is used on the affected areas. The light source activates the Levulan® resulting in the killing of the patient’s acne bacteria*. PDT also helps reduce the acne patients’ oil glands.
Patients are advised to avoid light for 48 hours after their PDT or laser treatment. Sunblock must be applied every 1-2 hours.
Photodynamic Therapy (PDT) to Treat Precancerous Cells
As previously mentioned, PDT is approved by the FDA for the treatment of actinic keratosis, which is considered a precancerous lesion. When treating actinic keratosis with Levulan® and PDT or laser, the light source or laser activates the Levulan® which preferentially takes up the precancerous cells and the sebaceous glands.
Dr. Rebecca Baxt and Dr. Saida Baxt typically cover the entire area of the patient’s skin rather than just the individual spots or precancerous lesions. This is done as a precaution to also remove any spots that are very small and cannot be seen with the naked eye. This preventive treatment works to keep the tiny spots from growing and becoming cancerous.
