Photodynamic Therapy

Insider Information: Photodynamic Therapy (PDT) For Acne

Photodynamic therapy is an excellent alternative to Accutane (isotretinoin). It achieves similar results and targets acne only where it is.

OMNILUX - PDT for acne and cancer treatment

Photodynamic therapy is covered by insurance for skin cancer / precancer treatments only. It is not covered for acne, scars, sebaceous gland hyperplasias, and skin rejuvenation.

65-70% of our patients fully control their acne after 4-6 PDT treatments ($600 / treatment) when performed every 4 weeks.

I apply Ameluz photosensitizing agent (rather than the Levulan Kerastick, which I find less effective for acne treatment) and let it incubate on the skin under Seran wrap for 1.5 hours and then activated by red light 633 nm for 3-20 minutes. The exact time will be determined by the tolerance or any redness occurring on the skin during activation.

After the treatment, sun light and fluorescent light protection is crucial for 42 hours after the application of the Metvixia. Most people who undergo PDT have some redness mild swelling for 24 hours after each treatment.

5% of patients experience a severe reaction with bright redness, swelling, and reactivation of acne that lasts intensely for one week and may require oral or topical steroid for several days and oral antibiotic for 10-14 days. If this rare reaction occurs, residual redness on the face may take up to 3-4 weeks to fully resolve. In those who have this severe reaction, only one treatment rather than 4-6 is typically necessary to control the acne. While nobody is pleased while in this severe phase, our patients uniformly said they would do it again given that their acne is gone afterwards or needs only minimal topical medication for control. The severe reaction can be avoided if the incubabtion time is reduced. However, for the majority of people that would mean undertreatment and payment for an ineffective treatment.

photodynamic therapy - PDT - Treatment
  • Expected Results
    • This photosensitizing treatment effectively treats inflammatory acne, rosacea, sebaceous gland hyperplasias as well as precancerous conditions and superficial skin cancers.
  • Preparation
    • Levulan Kerastick / Metvixia contains a clear solution of aminolevulinic acid that is applied to the skin for 1 to 2 hours (acne), or several hours (cancers / pre cancers), prior to activation with a light source.
  • Post treatment instruction
    • Sun exposure and fluorescent light exposure must be strictly avoided for 24-48 hours after the treatment as photosensitivity from the Levulan Kerastick / Metvixia persists for this amount of time. A zinc oxide / titanium dioxide containing sunscreen must be applied to any treated area that can not be covered by clothing.
  • Time to desired results
    • 4-6 treatments every 2-4 weeks for acne. Usually two treatments, 2 weeks apart, for precancerous conditions/skin cancers. 2-6 treatments, two weeks between treatments, for superficial skin cancers.
  • Contraindications
    • Sensitivity to aminolevulinic acid, photosensitizing medications.
  • Lasting results
    • Many months with acne/rosacea, up to 10 years with skin cancer.
  • Downtime
    • Gradually diminishing redness and peeling for several days. Crusting occurs when skin cancers are present. Topical acne/rosacea treatments can be resumed when the redness has faded.

What WE DID WELL

(Answers:674)

Clean, bright, well appointed office

#12021-09-01

Didn't have to wait long to see to get into the room, or for the doctor to come in. The doctor & medical assistant took the time to explain the medications, when I should take them, how much I should use and what they would do to my skin.

#22021-11-08

Office staff was very polite and Dr was very thorough and everything was automated!

Having the classical music from WRTI radio station in the background as well as the amicable staff

I liked that the doctor was well informed about the proper medicines to help me with my acne, and also was well informed about my medical condition, and was able to prescribe medication to help both!

(answers:373)

All aspects of care were remarkable--much better than I've encountered elsewhere.

#12021-12-28

Keeping me from dying of skin cancer would be good (I will behave and do the checks and annual exam to help out!!!)

#22010-11-29 11:47:11

Get some better parking spaces

#32021-07-31

Cookies and Milk! Seriously, I love coming in and being seen promptly. More importantly, I like the fact that the doctor was not distracted and there was not a single interruption.

#42021-03-14

I had an appointment for a consulation for sun damage. Unfortunately, I need to see either a doctor or PA for my issue and this was not included in my appointment, so I need to make another trip. It is difficult for me to carve time out of my work day to take care of personal needs, so this is creating an inconvenience for me. I would have preferred to had the complete consultation done in one appointment.

#52011-02-14 14:14:53

fantastic service

#62021-09-18
