2003 Lumenis ClearLight system.
This is a great system for treating mild to moderate acne.
Here is what Lumenis says about the Clearlight:
HIGH INTENSITY BLUE LIGHT FOR THE DESTRUCTION OF P. ACNES
ClearLight Acne PhotoClearingTM (APCTM) technology gives physicians a new tool designed to clear moderate inflammatory acne without side effects, patient discomfort, photosensitivity or downtime. ClearLight uses a high-intensity, enhanced, narrow band light source (405-420 nm). Before - APC technology uses high-intensity, 405-420nm wavelength light, which permeates the tissue to reach the P. acnes target safely and effectively. During - This unique spectrum of high-intensity light triggers the proliferation of endogenic porphyrins, which attack and destroy P. acnes bacteria within the skin. After - ClearLight creates a destruction rate that surpasses the normal proliferation rate of the P. acnes bacteria, assuring a significant decrease in P. acnes bacteria
