PDT is performed at our Boulder clinic similar to other facial treatments. Your dermatologist will cleanse your face thoroughly at the beginning of the service. Immediately following a scrub, microdermabrasion, or chemical peel in order to increase penetration. A clear liquid, aminolevulinic acid, is applied to the entire surface of the skin to incubate for a half an hour to three hours, depending on the skin condition and the light that is used. Your physician will determine which light source is best suited for your particular skin condition. Light sources can be a blue light, red light, intense pulsed light, or pulsed dye laser. The only discomfort that patients will typically experience is a burning sensation, which will be lessened by fans or cool air.

Post-treatment, the patient’s skin will be extremely light sensitive for the next 48 hours while the medication is metabolized. Patients must keep the treated area protected during the 48 hour period and should avoid the outdoors as much as possible. A thick and high SPF sunblock with zinc is best if patients need to be outdoors. Peeling and redness are likely to occur for a week to two weeks after the treatment.
