Go Green with 532 nm
In a side-by-side, split face clinical study published in Dermatologic Surgery*, the 532 nm KTP laser was at least, if not more, effective than the 595 nm pulsed-dye laser in all subjects with facial telangiectasia and telangiectatic erythema (redness). The study also showed that the 532 nm KTP laser achieved quicker clearing of targeted lesions in addition to increased patient comfort when compared to the 595 nm pulsed-dye laser.
