PhotoDynamic therapy is a cosmetic treatment that pairs the application of a photosensitizing agent, such as aminolevulinic acid or Luvelan Kerastick, and Intense Pulsed Light or LED Blue Light. The combination provides a reaction that inflames the skin cells. As those inflamed cells are shed, the skin takes on a youthful glow and becomes smooth in texture.
Conditions Treated with PhotoDynamic Therapy
PhotoDynamic therapy is popular for the treatment of acne, rosacea, and wrinkles. Actinic keratosis is another condition treated with PhotoDynamic therapy. This condition occurs when thick, scaly patches form on the face and scalp. Since actinic keratoses can progress into squamous cell carcinoma, it’s important to treat the condition as early as possible.
It has also been found that treatment of pre-cancerous cells is just as effective when done through PhotoDynamic therapy. As a result, general plastic surgeons use PhotoDynamic therapy to treat sun damaged skin. By treating pre-cancerous sun spots, the cells are killed before they turn into skin cancer. Dr. Masri recommends several treatments every three weeks, or more depending on the severity of the sun damage.
Additionally, PhotoDynamic therapy is used as a treatment for certain cancers, such as esophageal and a specific form of lung cancer. When Photofrin, a photosensitizing agent, is exposed to the specific treatment light, oxygen forms and kills cells within the specific area. Doctors inject Photofrin into the area near the cancer. Healthy cells do not hold onto the photosensitizing agent, but tumorous cells retain it. After a day or two, the cells are exposed to the light which will kill them.
