Levulan Kerastick Photodynamic Therapy
What Levulan PDT Treatment is for
Levulan PDT treatment is for the treatment of actinic keratoses (AK's), rough textured, dry scaly patches on the skin that are caused by excessive exposure to UV light. AK's are most commonly found on the face, scalp, ears, neck, hands, and arms. AK's are the most common precancer and while most remain benign, they have the tendency to develop in to squamous cell carcinoma.
According to a study in the Journal of Dermatologic Surgery, over ninety percent of 49 subjects who underwent four or more full-face PDT treatments at 3-week intervals showed visible improvement in pore size, wrinkling, skin coarseness, irregular pigmentation, and telangiectasias. Because of this, we also recommend PDT for patients who are interested in looking younger without undergoing cosmetic surgery or using injectable fillers. PDT is effective because it has been shown to both kill bacteria associated with acne (P. acnes) and shrink the oil glands, so the pores appear smaller
What happens during the treatment
PDT treatment is a two-step process.
Step #1: Levulan Kerastick Topical Solution is applied to the AK. The solution is absorbed by the AK cells where it is converted to a chemical that makes the cells extremely sensitive to light. The healthcare professional will then have you wait the recommended time before Step #2.
Step #2: The AK cells are exposed to the BLU-U Blue Light Photodynamic Therapy Illuminator. The reaction that occurs destroys the AK cells. Step #2 usually lasts about 17 minutes.
Why Levulan PDT Treatment might be right for you
Because there is no way to know which AK's will develop into skin cancer, PDT is an excellent option for treating potenital pre-cancerous AK's. There is no prescription to fill and no daily medication.
You cannot expose the treated lesions to sunlight or other forms of bright light (exam room examination lamps, operating room lamps, tanning bed lights, and household lights at close range such as your TV, tablet, computer, or reading lamps) for at least 48 hours after treatment. For this reason, we typically perform PDT treatment on Fridays so you have the weekend to stay out the sun.
