The solution is called Levulan (5-aminolevulinic acid or ALA) and it is applied to your skin for 30-90 minutes. Afterwards, a blue light is shinedover your skin for 17 minutes to activate the solution. This reaction between the light (photo) and the chemical treats sun damaged pre-cancers called actinic keratosis (AK) . Sun damage, fine lines, and blotchy pigmentation also improve although these treatments are not FDA approved. PDT may also minimize pores and reduce oil glands, improving stubborn acne vulgaris and acne rosacea.  \nHOW MUCH IMPROVEMENT CAN I EXPECT?  \nThe greatest improvement is in reducing precancerous AKs. The cosmetic improvements, such as smoother texture, less oily skin, smaller pores, and less acne may also be seen and is patient dependent. Some patients see mild while others have dramatic improvement.  \nHOW MANY TREATMENTS WILL IT TAKE TO SEE THE “BEST RESULTS”?  \nTo achieve maximum improvement of pre-cancerous (actinic keratoses) sun damage, skin tone and texture, a series of three treatments 3-5 weeks apart is most effective.(Some patients with just actinic keratoses are happy with one treatment. )  \nWHAT ARE THE DISADVANTAGES?  \nFollowing PDT, the treated areas can appear red with some peeling for 2-7 days. Temporary swelling of the lips and around your eyes can occur for a few days. Darker pigmented patches called liver spots can become temporarily darker and then peel off leaving normal skin. (This usually occurs over seven to ten days. ) Maintenance treatments may be necessary.  \nWHAT ARE THE ADVANTAGES?  \n1. Easier for patients than repeated freezing (liquid nitrogen) , Efudex (5-FU), or Aldara because the side effects are minimal, rapid healing, and only 1-3 treatments are required. (71% improve after one treatment, 92% improve after two treatments, and almost 100% after 3 treatments) .  \n2. Discomfort varies with each patient but only lasts for 17 minutes during treatment, compared to weeks of irritation and wound care with Efudex or Aldara.  \n3. Uniform improvement: PDT treats an entire region and the whole area improves. Both visible and non-visible precancers are treated. White spots, which can be seen with freezing is not seen with PDT.  \nIn summary, PDT matches the “Ideal treatment” for sun damaged skin:  \n􀁸 Well tolerated-single 17 minute treatment (three treatments over 3-5 weeks for best results)  \n􀁸 Easily performed by a specialty clinic environment  \n􀁸 Non-invasive (no needles or surgery required)  \n􀁸 Excellent cosmetic outcome (particularly in cosmetic sensitive areas of the face)  \nTREATMENT STEPS  \n1. Patients who have a history of recurring cold sores (Herpes simplex type I) should start oral Valtrex 500 mg tablets, two tablets twice daily for three days – starting this prescription the morning of your PDT treatment. The prescription for this product will be ordered for you.  \n2. Make sure your skin is clean and free of all make-up, moisturizers, and sunscreens. Bring a hat, sunglasses, and scarf, when appropriate, to the clinic.  \n3. You must sign a consent form.  \n4. An acetone scrub is performed. This will increase the absorption of the Levulan and maximize your benefits.  \n5. Levulan is applied topically to the whole area-whole zone to be treated (such asthe whole face, back of the hands, extensor part of the forearms) .  \n6. The Levulan is left on for 30-90 minutes before any light treatment.  \n7. The Levulan is activated with the Blu-U (blue light) and treatment last 17 minutes. This unique light activates the Levulan beginning with low energy levels. There may be some stinging and burning during treatment but most patients tolerate it well.  \n8. Post-treatment instructions will be given to you to care for your improved skin.  \nPHOTODYNAMIC THERAPY FOR ACNE  \nWHAT IS PHOTODYNAMIC THERAPY?  \nPhot","cbCaikTMbKuIfDrg","https://ap.wps.com/l/cbCaikTMbKuIfDrg","pdf",1858277,"English","# What is Photodynamic Therapy?\n## How much improvement can I expect?\n## How many treatments are needed for best results?\n## What are the disadvantages and advantages?\n## Treatment steps\n# Photodynamic Therapy for Acne\n## Benefits\n## What can I expect after the treatments?\n# Photodynamic Therapy for Actinic Keratoses (AKs)","[{\"question\":\"How does photodynamic therapy (PDT) work?\",\"answer\":\"Levulan (ALA) is applied to the skin, then blue light (BLU-U) is shined on the area for about 17 minutes to activate the solution and treat targeted sun-damaged precancers and conditions.\"},{\"question\":\"What improvement can patients expect for actinic keratosis (AK)?\",\"answer\":\"The greatest improvement is reducing precancerous AKs.
