Photodynamic Therapy (PDT) With Levulan is a special treatment performed with a topical photosensitizing agent called Levulan. The procedure combines light and a special light-activated topical photosensitizing agent called Levulan. Levulan is a 20% solution of Aminolevulinic Acid (ALA). ALA is a "natural" product found in all humans throughout the body. It is a precursor for hemoglobin synthesis which means you wouldn't be able to make red blood cells to carry oxygen without ALA in your body.
Levulan, which is a clear painless solution, is applied to your skin and left on for 15–60 minutes. The Levulan is absorbed by active cells like acne sebaceous gland, making the targeted acne cells more sensitive to the light. During the procedure, the ALA is activated with the correct wavelength of light within the non-UV blue spectrum. This combined interaction of the solution and the light is what gives rise to the term "photodynamic therapy."
The treatment, also known as "ALA/PDT treatment" removes sun damaged pre-cancerous zones and spots called actinic keratoses (precancerous growths that develop from prolonged, cumulative sun damage over the course of your lifetime). Sun damage, fine lines, and blotchy pigmentation are also improved because of the positive effect of Levulan and the light treatment. ALA/PDT treatments also have the ability to minimize pores and reduce oil glands, effectively treating stubborn acne vulgaris, acne rosacea, and improve the appearance of some acne scars.To learn more about Photodynamic Therapy (PDT/ALA), Ask The Expert, Contact Us or Make an Appointment for a Free consultation.
