PHOTODYNAMIC THERAPY OVERVIEW:
Photodynamic therapy (PDT) is a therapeutic method used with increasing frequency in dermatology. Since its first clinical trial in 1903, dermatologists are continuing to discover its full potential. PDT is FDA-approved for the treatment of pre-malignancies and certain superficial malignancies, but its off-label uses continue to increase. At Atlantic Dermatology and Laser, we are increasingly utilising PDT not only as a field treatment for extensive sun damaged skin, but also to control resistant, hard-to-treat active acne. Our integrative approach means that we strive to offer our patients alternatives to the traditional systemic acne medications which either disrupt the delicate gut microbiome or require blood monitoring and strict compliance. PDT is one such alternative. We have also added PDT into our therapeutic armamentarium of photo-rejuventation therapies.
The concept of PDT is deceptively simple in that it requires only three ingredients: a photosensitizer, a light source, and oxygen. The therapeutic effect is achieved by light activation of a photosensitizing agent, and in the presence of oxygen, reactive oxygen intermediates are formed which then target areas of concern. PDT is safe and effective and produces excellent cosmetic results with few adverse effects. Our dermatology team at Atlantic Dermatology and Laser are accomplished at optimising the cutting-edge applications of this efficacious modality and look forward to exploring how PDT can help you.
