PDT Acne TreatmentAt our San Diego cosmetic dermatology office, our doctors are well-experienced with PhotoDynamic Therapy (PDT) treatments.

PDT is a non-invasive procedure used to treat a variety of skin conditions. It is a special treatment performed with a topical photosensitizing agent called Levulan (5-aminolevulinic acid or ALA) or Metvixia (methyl aminolevulinate) which is activated with the correct wavelength of light. This treatment is also commonly referred to as “ALA or PDT treatment”, Levulan photofacial or Photodynamic Acne Therapy.

Our physicians have vast experience with PDT, and have been involved in clinical research, published peer-reviewed journal articles and lectured on the topic worldwide. Furthermore, Dr. Goldman is the lead author and editor of the preeminent Photodynamic Therapy textbook, now in its second edition, which is used to teach physicians around the world about the advanced techniques we use to help our patients achieve maximum results.

How does PDT work?

Levulan PDT San DiegoPhotoDynamic therapy in San Diego is for the treatment of acne and other skin diseases involves the use of photochemical reactions to photosensitizing agents, light, and oxygen. It involves three steps. First, microdermabrasion is done and followed by the photo-sensitizer which is applied to the skin surface and taken up by the acne lesions. Then 4 specific wavelengths of lasers ( PDL, IPL, Blue Light and Red Light) are applied toward the acne lesions, activating the photo-sensitizer in the presence of oxygen.

Because the photo-sensitizer is preferentially absorbed by the acne lesions and the light source is directly targeted on the lesional tissue, PDT achieves dual selectivity, minimizing damage to adjacent healthy structures. It is mediated by oxygen-dependent photochemical reactions, resulting in destruction of the acne lesion.

The purpose of this treatment is to initiate photochemical reactions, and not to heat or mechanically change tissue as seen in other dermatologic uses. Ultimately, Photodynamic Therapy is a very safe procedure that can provide patients with outstanding results with minimal downtime and risk.
