PDT Blue Light therapy
Photodynamic Therapy (PDT) is a treatment that combines light with a photosensitizing solution to improve sun damage, pre-cancerous cells (actinic keratosis), acne and rosacea.Q: How does PDT work?
A: In our office, a Levulan, a photosensitizing solution, (20% aminolevulinic acid) is applied to the surface of the skin to be treated, where it is absorbed preferentially by abnormal or pre-cancerous skin cells as well as oil glands and pores, making these more sensitive to laser or light. After the incubation period (the time the solution sits on the surface of the skin), the DUSA light source is used to activate the solution. This combination therapy leads to a destruction or reduction of abnormal cells and excessive oil gland cells and results in healthier, smoother, and clearer skin. Multiple treatments are required and a medical visit is necessary prior to treatment.
Q: How is PDT unique?
A: Other methods of therapy, such as topicals, result in long periods of downtime or the possibility of white spots or scars on the face. PDT is just as effective but only requires 2-4 days of social downtime, treats the entire face or area and not just spots, and improves the cosmetic appearance of the skin.
Q: Does PDT treatment replace liquid nitrogen, Efudex, Carac and Aldara?
A: PDT will hopefully minimize the needs for these other treatments. However, they may still be necessary for thicker lesions or stubborn areas.
Q: Who is a candidate?
A: Anyone with sun damaged skin, actinic keratoses (pre-skin cancers), acne, or inflammatory rosacea. Patients cannot have treatment if you are:
- pregnant
- have been on Accutane within the past 6 months
- Tanned or sunburned (more susceptible to potential side effects such as blisters or crusts)
A: PDT should be scheduled at a time when you do not have outdoor activities planned for 2 days. Also, it should not be scheduled less than ten days before a special event as there will be some redness.
Q: Is PDT covered by insurance?
A: The blue light treatment for actinic keratosis is covered by Medicare and BCBS. We would be happy to pre-approve your treatment to confirm coverage by your insurance company.
Q: What should I do to prepare for my treatment?
A: Patients must arrive at SkinSmart Dermatology with a freshly cleansed face- free of makeup, aftershave, moisturizers, and/or sunscreen. As you MUST completely avoid sun exposure for 48 hours following your treatment, we require our patients to bring a wide brimmed hat (no baseball caps or sun visors) and an umbrella to your appointment.
