Here is what Lumenis says about the Clearlight:
HIGH INTENSITY BLUE LIGHT FOR THE DESTRUCTION OF P. ACNES
Acne is one of the most common and stubborn skin problems. Regardless of skin type or lifestyle, approximately 80% of the population will suffer from acne at some point in their lives. Yet many patients fail to respond adequately to current treatment options and others develop problematic side effects. Further, the cost and duration of acne treatment with topical medications and oral antibiotics make standard therapy far from ideal.
Now, a novel device called the 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
