Photodynamic Therapy (PDT)

Photodynamic therapy (PDT) is a two-stage treatment that combines light energy with a drug (photosensitizer) designed to destroy cancerous and precancerous cells after light activation. Photosensitizers are activated by a specific wavelength of light energy, usually from a laser.

BLU-U targets AKs (actinic keratoses) precisely. The BLU-U Blue Light Photodynamic Therapy Illuminator is specifically designed to deliver light of an appropriate wavelength, energy and penetration in order to activate the photosensitizer protoporphyrin IX (PpIX) after LEVULAN KERASTICK has been applied to AK lesions and allowed to incubate.

  • Not all light sources are designed the same. The patented U-shaped of BLU-U allows for uniform light coverage of the treatment area in a single illumination session.
  • BLU-U covers more of your patient with an active working area of 214 square inches  – 14 times larger than the red light of other PDT treatments.
  • Blue Light penetrates up to 2mm into skin where AKs reside.
