What is Levulan used for?

The Levulan Kerastick for Topical Solution plus blue light illumination using BLU-U Blue Light Photodynamic Therapy Illuminator is a two-step (drug plus blue light) treatment used to treat pre-cancerous skin lesions of the face or scalp called actinic keratoses (AK).

Who should not be treated with Levulan?

You should not be treated with Levulan if you have:

  • Skin sensitivity to blue light
  • Porphyria (a disorder of the metabolism that can lead to sensitivity to light)
  • Allergies to chemicals called porphyrins

General Precautions with Levulan:

The treated lesions are sensitive to light therefore, people being treated will need to avoid sunlight and sources of bright light for at least 40 hours after Levulan is applied.

What should I tell my doctor or health care provider?

There are other medications that increase sensitivity to light. Tell your doctor or health care provider if you are using any other medicines. These medicines include:

  • thiazides (used to treat high blood pressure)
  • tetracyclines, fluoroquinolones, griseofulvin, or sulfonamides (used to treat infection)
  • sulfonylureas (used to treat diabetes)
  • phenothiazines (used to treat serious emotional problems)

What are some possible side effects of Levulan? (This is NOT a complete list of side effects reported with Levulan. Your health care provider can discuss with you a more complete list of side effects.)  

Blue light treatment may cause tingling, stinging, prickling, or burning feeling of the treated areas. These feelings should improve at the end of the blue light treatment and should end within 24 hours.

Following blue light treatment, the AKs and, to some degree, the surrounding skin, will redden. Swelling may also occur. These changes should reach a maximum the day after BLU-U treatment. However, these changes are temporary, should improve markedly by the end of the first week, and should be completely gone by 4 weeks after treatment. Other side effects at the treatment sites may include:

  • Scaling
  • Itching
  • Changes in skin color

subaceous hyperplasia

I have an RX for Levulan Kerastick from the medical aesthetician I have been getting facials from. I have tried 7 major pharmacies but none of them have heard of it and it is not in their data base to order. How do I obtain it so my medical aesthetician can do the photodynamic therapy I require to remove the Subaceous Hyperplasia bumps on my face? Should I tell her to order it from Guidelines INC. or can I order it from them?

Please advise.

Thank you.


I had a levulan treatment with a light Photodynamic Therapy, and I have had minumial redness and no side effects. Is this normal? I am trying to elminate hormane (brown spots) and prevent skin cancer, since it runs in both sides of my family.

Im 31 and had acne. I have tried everythink in the market and nothing helped me. I have had 3 levulan treatments and my acne is almost clear. Now i had applied a co2 laser terapy in order to clear the scars and i plan to have a 4 levulan treatment in a month. I really recommend the treatment.

I just had levulan treatment 2 days ago, for treating acne. I have intense redness in my face. Does someone knows how many days my face will be red? And how many treatments are recomended to make acne dissapear?


I am 39 years old and have received 2 Levulan and Blu-U light treatments for acne. After the first treatment my acne was slightly better. My second treatment was horrible. My face was severely red and swollen for 4 days. I could not go out in public for 5-6 days. I looked like I had some kind of skin eating disorder. It was also very painful. I'm supposed to go for a third treatment, but don't know if I'm going to go through it again.

I am on my second treatment(2nd week into it and 2nd application of levulan) and was wondering how far apart should I go in between treatments? I have been scheduling it(levulan) every two weeks, should I wait 3-4 weeks? if I spread my treatment out will I Have better results then if I go every other week? if someone could help me out I would greatly apreciate it! and I also wanted to know if I can still take retin-a during my treatment? thanks to whoever can help me get some answers to these questions!


1-07-2006 I have had 2 treatments with levulan. I have not noticed a dramatic difference in my cystic acne. I was told that it would take time and that it is a process. I have noticed the brown spots on my face have been diminishing from each treatment... that is a huge plus. I would like to know what the time frame normally is for seeing a turnaround with the cystic acne?? Like I said, I have just started this treatment series a couple months ago and will go for a third treatment this week. If this does not help the cystic acne, then next I will opt for acutane. It is not as if I have not tried other avenues... I am 39 years old and have been dealing with this for 8 years!! It is frustrating to say the least.

I have had very good experince using Levulan combined with Blue Light. My face has not only cleared up but somehow also look younger. I have had many compliments after this treatment. Highly recommended treatment for not just AK but also to those who wants facial rejuvenation!
