Photo Dynamic Therapy
Hard-to-treat acne can require "power-level" treatments. A new procedure that treats resistant, hard-to-treat active acne combines light and a special light-activated solution that targets and destroys acne activity. This treatment also diminishes older acne scars leaving your skin smoother. The procedure is called Photo Dynamic Therapy.
Photodynamic Acne Treatment (PDT)is a process by which a photo sensitizing agent (Levulan) is applied to your skin. A Photo sensitizing agent is a special solution applied to the skin that is activated by a specific wavelength of light, which “turns it on.” Levulan has been used extensively for the treatment of a variety of different skin conditions.
Levulan is a 20% solution of Aminolevulinic Acid (ALA). ALA is a “natural” product found in all humans throughout the body. Its it is a precursor for hemoglobin synthesis. (You wouldn’t be able to make red blood cells to carry oxygen without ALA in your body.)
Understanding Acne
Acne results from the obstruction and inflammation of the sebaceous glands, and it affects 80% of the human population. Acne typically begins in adolescence with hormonal changes. However, there are many older individuals who suffer from “adult acne.”
There are different levels of acne ranging from milder comedonal (blackheads and whiteheads) to moderate, pustular, on to severe cystic acne. In many cases, several or all of these levels of acne can be present on an individual simultaneously.
Different Levels of Acne
Moderate acne may include blackheads and whiteheads in addition to papules —inflamed lesions that appear as small, reddish or pinkish bumps that can be sensitive to touch—or pustules—inflamed, white-centered bumps that can be red at the base.
Severe acne is characterized by nodules —large, painful, solid lesions that appear as lumps under the skin—and cysts —deep, inflamed, pus-filled lesions that can be very painful. Nodules and cysts are inflammatory and can cause scarring.
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.
Photodynamic Acne Treatment Procedure
The Levulan, which is a clear painless solution, is applied to your skin and left on for 15-60 minutes. It is then activated with a specific wavelength of light called BLU-U or Clear-Light. This takes about 8-10 minutes.
The Levulan is absorbed by active cells like acne sebaceous gland,. making the targeted acne cells more sensitive to the light. This combined interaction of the solution and the light is what gives rise to the term "photodynamic therapy." The Levulan will also target sebaceous hyperplasia (which are those small (1-3mm), benign bumps under your skin) and the papules of acne rosacea.
An important part of the treatment program is medical extraction of blackheads and acne pustules. This procedure will expedite the improvement in your skin condition by cleaning the pores of hardened sebum and infected debris.
The treatment reduces skin oiliness and minimizes the appearance of pore size. The entire skin texture improves following a Photodynamic Acne Treatment.
Advantages of PDT
The advantages of PDT are rapid treatment of acne lesions all over the face, no scarring, no surgical excisions and no systemic side effects. The skin appears refreshed and younger following these treatments. We advise 2-3 treatments at 2 to 3 week intervals to obtain optimal results.
Downside of PDT
The “downside” of Photodynamic treatment (PDT) is that your skin will be red and have some skin peeling (and crusting if you have skin cancers) for several days after the treatment. Usually, the first 1-2 days are the worst. Pressed mineral base powder (available in our office) will hide most of the redness. You must remain indoors the day following your treatment to avoid sun exposure, as you are photosensitive for about 24 hours after PDT. Topical acne lotions can be used in between your Levulan treatments once the redness has settled down over a period of a few days.
