Feb. 12, 2010 -- iPhone users love their apps, so it's no surprise that AcneApp, a light-based therapy, is drawing interest from the blemish-prone who like the concept of zapping zits while talking to friends.
It's supposed to work like this: Download the application and hold the phone to the skin so the light therapy can do its work. Multitask if you wish, remembering to switch sides so your entire face gets the treatment.
But more than four months after its release, there are still no clinical studies proving it works. Other dermatologists express doubt it could help, and users are giving it mixed reviews -- from terrific to skeptical.
AcneApp is listed as No. 1 in the medical category on iTunes for Jan. 27, yet the Apple store web site cautions that ''the app is for entertainment purposes only and is not intended for treatment of any disease or medical condition."
AcneApp was developed by Houston dermatologist Greg Pearson, MD, who wasn't available to talk to WebMD but concedes in a YouTube video that studies need to be done to verify the app's effectiveness.
While light therapy for acne is sometimes effective, according to other dermatologists, they're skeptical the iPhone app has enough power to blast away zits.
At $1.99 per download, AcneApp costs less than most over-the-counter acne remedies.
Pearson couldn't elaborate, according to his office staff. He wasn't accessible by email, either. The office staff says they have no brochures on the app, nor do they provide information on it to patients.
But in the YouTube video, Pearson explains that the app is to be applied directly to the skin for about two minutes a day. While admitting that studies are needed, he says that the idea is ''really based on some science."
When the app is downloaded, users are asked to chose a light option, with the red and blue alternating light recommended.
The device gives off wavelengths of 420 nanometers of blue light and 660 nanometers of red, according to the product information. Blue light, according to the app, fights acne-causing bacteria, while red light helps heal skin.
Users are warned not to use the app if they are on medication that makes the skin light sensitive or if they have medical conditions that make the skin sensitive to light. They are cautioned to stop using AcneApp if problems develop.
