What is photodynamic therapy?

During a photodynamic therapy session at Z-ROC Dermatology, Dr. Zarraga or Dr. Wongkittiroch applies a photosensitizing agent called aminolevulinic acid (ALA), in either a solution or gel form (Levulan or Ameluz, respectively), to your skin. Although an application of an acid onto your skin may sound painful, the application of ALA is not uncomfortable in any way.

The ALA is then allowed to incubate on your skin overnight. The following morning, ALA must be activated by a light source, and although the ALA can be activated by a variety of light sources, at Z-ROC Dermatology, your dermatologist activates the ALA with a light device called intense pulsed light (IPL); the same light device used for photorejuvenation and photofacials. This effect activates and destroys abnormal cells, leaving healthy skin unharmed.

Dr. Zarraga or Dr. Wongkittiroch personally performs the activation portion of the procedure with IPL, and it takes approximately 15-30 minutes.

The sensation of the treatment has been compared to multiple rubber band snaps; however, the treatment can be paused if you are experiencing significant pain or discomfort. Immediately after your treatment, your pain should be minimal to nonexistent.

What products should I use after PDT?

The dermatologists at Z-ROC Dermatology recommend a variety of products to maximize your benefits from PDT, including:

  • Z*RO Sun Sheer Mattifying Antioxidant Sunscreen
  • Z*RO Downtime Ultra Gentle Revitalizing Cleanser
  • Lasercyn Dermal Spray
  • Z*RO Downtime Intensive Antioxidant Recovery Cream

These products are specially formulated and recommended for use after a photodynamic therapy session. While using these products, Dr. Zarraga and Dr. Wongkittiroch recommend that you discontinue the use of all other skincare products.
