BoSidin is the first to introduce medical-grade technologies used in cosmetic centers into at-home hair removal devices. OPT strengthens each effective pulse, giving you the same intensity normally only found in medical hair removal devices. Light strikes follicles deep at the root, easily removing even the toughest hair. By rapidly emitting soft pulses of light, medical-grade continuous pulse technology allows heat to build up at the root and effectively suppress hair regrowth.
