Blu-U Photodynamic Therapy Q & A

What is BLU-U Photodynamic Therapy?

BLU-U Photodynamic Therapy uses Levulan®, a topical medication, that specialized blue light activates. The treatment:

  • Shrinks oil glands
  • Minimizes pores
  • Treats redness and inflammation caused by acne and rosacea

Photodynamic therapy is also effective against pre-cancerous lesions called actinic keratoses. 

Levulan undergoes a chemical reaction when touched with the blue light’s specific wavelength and intensity. This causes redness to minimize and pre-cancerous lesions to shrink away.

How does BLU-U Photodynamic Therapy treat acne?

Teens and adults with inflammatory acne that causes redness may benefit from blue light photodynamic therapy. Candidates usually have moderate acne and are uncomfortable taking antibiotics to ease inflammation and redness.

The light BLU-U emits gently kills P. acnes bacteria. It isn’t effective against whiteheads and blackheads, however. Dr. Cortez-Sammons and the team suggest facials with extractions to help with these acne precursors.

BLU-U Photodynamic Therapy isn’t painful or hot. You usually visit Transformation Health & Wellness two times per week for a 15-20 minute session that involves sitting in front of the light. After a few sessions, you notice your acne is more controlled and less inflamed.  

How can BLU-U Photodynamic Therapy treat actinic keratoses?

Actinic keratoses, or AKs, are often called sun spots or lesions. They’re red or reddish-brown, rough, scaly and flat, often appearing on areas frequently exposed to the sun, such as the:


  • Nose
  • Ears
  • Forearms
  • Chest
  • Back of the hands


They can range in size and be as small as a pinhead up to as large as a quarter.

Actinic keratoses form due to accumulated sun exposure. That doesn’t only mean time spent lounging on the beach or at the pool – it’s the times you’re unprotected with sunscreen or clothing while driving, walking to the mailbox, or walking the dog. Often, AKs develop into skin cancer. Since there’s no way to know which AKs will become cancerous, it’s best to eradicate them and eliminate the risk.

BLU-U Photodynamic Therapy offers a two-step treatment procedure for actinic keratoses. First, your provider applies the Levulan medication to the AK lesions, and the cells absorb it, becoming extra-sensitive to light. You’re then exposed to the specialized blue light, which in turn destroys the AK cells. Your treatment is complete after two visits scheduled within 24 hours.

What should I expect with BLU-U Photodynamic Therapy?

Bring any sun protection, such as hats and umbrellas, to your appointment. After treatment, you want to avoid exposing treated areas to direct sunlight or bright light for at least 40 hours. You should also avoid tanning beds, operating room lights, and household lights at close range.

During treatment, you may experience stinging or burning, but this subsides quickly – usually within a few minutes or 24 hours. Most people tolerate blue light treatment well. Areas treated with the blue light may also scale or crust for up to four weeks following treatment.
