Photo Dymanic Therapy – What is PDT?

Photodynamic therapy (PDT) is a medical treatment that uses a photosensitizing drug (a drug that becomes activated by light exposure such as IPL ) and a light source to activate the applied drug.

PDT in Acne

In dermatology, PDT with the photosensitizer are used for the treatment  acne, rosacea, skin cancer, sun damage, cosmetic skin improvement, oily skin, enlarged sebaceous glands, wrinkles, rejuvenation (anti-aging).

The Procedure

The photosensitizer, 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 Blue light or Clear-Light. This takes about 8-10 minutes.

The photosensitizer 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 photosensitizer 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.

Who suitable for PDT?

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.

Risk or side effect

The side effect of Photodynamic treatment (PDT) is that your skin will be red and have some skin peeling 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 photosensitizer treatments once the redness has settled down over a period of a few days.

How many time do I need?

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.

After the treatment

You should avoid direct sunlight about 1-2 weeks
