Photodynamic therapy, also known as PDT is a procedure that treats a combination of changes in facial skin, as well as significant sun damage. It is especially helpful for removing pre-cancerous spots (actinic keratosis), treating acne, eliminating irregular pigmentation and improving skin texture, especially reducing pore size.
How Photodynamic Therapy works:
Photodynamic therapy works in combination with intense pulsed light or another light source in combination with microdermabrasion and Levulan, also known as aminolevulinic acid (ALA). Levulan is applied topically to the whole area to be treated. The Levulan is left on the skin to "incubate" and then activated with the appropriate light source. It works by targeting the sun damaged skin, reducing red and brown spots in the skin.
What to expect from Photodynamic Therapy:
Most patients experience minimal discomfort during PDT therapy within the standard course of treatment. You can expect slight redness and peeling/flaking of the outer skin cells up to 3-4 days following treatment. You will need to stay indoors for 24 hours following the procedure and avoid light since the PDT therapy is still active during this time.
