Laser System Treats Inflammatory Acne Vulgaris

A laser system that can increase collagen production by 99.5% and effectively treat many vascular disorders can also treat inflammatory acne vulgaris. This application has been cleared by the US Food and Drug Administration (FDA).

The system is a fast-pulsed dye laser that emits a wavelength of yellow light directly over problem areas. This heats small blood vessels, allowing them to open and release healing mediators that, in turn, encourage the natural healing process and stimulate collagen production. In a trial at Hammersmith Hospital (London, UK) involving 41 patients, a single five-minute treatment with the laser system resulted in a 50% improvement in acne lesion count. In addition, about 25% of the patients were acne-free after treatment.

"This noninvasive laser targets the skin's small blood vessels, so it does not cut or burn the outermost layer of the epidermis,” said Dr. Suzanne Kilmer, past president of the American Society for Laser Medicine. "Thus, no anesthesia is required. There are no side effects, treatment is pain-free, and the patient has no downtime as a result of this procedure.”

Called NLite-V, the laser system was developed by USA Photonics, Inc. (Nanuet, NY, USA), using the company's Smartpulse technology. The company states that NLite is the first major advance in the field of dermatology in more than 30 years.
