Photodynamic Therapy (PDT) in Ocala, FL

What are Actinic Keratoses?

Actinic Keratoses

Actinic keratoses are precancerous growths on the skin caused by long term exposure to ultraviolet radiation, usually in the form of sunlight or tanning beds. They frequently appear on sun exposure areas such as the scalp, face, back of the hands, and forearms, and are characterized by rough, dry lesions or patches that are easier to feel than to see. Because these precancers can develop into squamous cell carcinomas, treatment is recommended.

Photodynamic Therapy is a 2-step Treatment Procedure

Step 1: Application of the Levulan Kerastick® Topical Solution

Levulan Kerastick®

  • Levulan will be uniformaly applied to your AK lesions.
  • Your provider will direct you to wait the recommended time of 60-90 minutes in order to allow the solution to penetrate the targeted cells.
  • Avoid exposing the treated lesions to sunlight or bright light for at least 48 hours after application. Examples include household lights at close range or playing sports such as golf. Sunscreens will not protect against photosensitivity reactions caused by visible light during this time.

Step 2: BLU-U® Light Treatment


  • Before your BLU-U light treatment, the AKs to be treated should be gently rinsed and patted dry.
  • Your treatment with the BLU-U will take approximately 15 minutes.
  • Protective eyewear should be worn during your BLU-U treatment.
