A multi-center clinical study examined the effects of ClearLight treatments on more than 120 patients at six centers. The study utilized a high-intensity, 400 watt, enhanced (407-420 nm) metal halide lamp to deliver light to the acne-affected locations.

After eight bi-weekly treatments, 80% of the patients with mild to moderate papulo-pustular acne showed significant improvement of non-inflammatory, inflammatory and total facial lesions. Inflammatory lesion count decreased by a mean of more than 60%. Two weeks after the last treatment, the lesion count decreased by nearly 70%. No side effects of the treatment were observed.

Additional in vitro and in vivo studies have also demonstrated the effectiveness of the ClearLight in destroying P.acnes.

At present, additional multi-center studies are underway to further support the efficacy of ClearLight technology in treating acne.
