How much improvement can I expect?
Patients with severe sun damaged skin manifested by actinic keratosis, texture, and tone changes including mottled pigmentation and skin laxity may see excellent results.
You may also see improvement of large pores and pitted acne scars. Active acne can improve dramatically.
How many treatments will it take to see the “best results”?
To achieve maximum improvement of pre-cancerous (actinic keratosis) sun damage, skin tone and texture, a series of 2-3 treatments 2-4 weeks apart is most effective. Some patients with just actinic keratosis are happy with just one treatment. More treatments can be done at periodic intervals in the future to maintain the rejuvenated appearance of the skin.
What are the disadvantages?
Following PDT, the treated areas can appear red with some peeling for 2-7 days. Some patients have an exuberant response to PDT, and experience marked redness of their skin. Temporary swelling of the lips and around your eyes can occur for a few days. Darker pigmented patches called liver spots can become temporarily darker and then peel off leaving normal skin. (This usually occurs over seven to ten days) Repeat treatments may be necessary as medicine is not an exact science.
