The procedure, which 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.
The 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". Treatments target and destroys acne activity leaving your skin smoother.and in many cases makes it possible to discontinue the use of antibiotics such Accutane.
Levulan has been used extensively for the treatment of a variety of different skin conditions including actinic keratosis, 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.
Prior to Photodynamic Acne Treatment, the best available treatment option for resistant and cystic acne was Accutane. However, with Accutane there are many systemic* side effects including birth defects, liver abnormalities, mood depression, and virtually all patients get dryness and night vision changes.
*Systemic treatments are any medications that are taken orally, injected or infused that affect the entire body system. PDT Acne Treatment provides a viable alternative to all types of acne treatment without having negative systemic effects.
