Combined 755nm Alexandrite Laser With Bipolar RF for Hair Reduction

The study device (Helos) combines 755nm alexandrite laser energy with bipolar RF energy. The laser can deliver 0.25 to 100 ms laser pulses at a maximum of 20 J/cm2. Bipolar RF energy will be delivered across the laser beam via two appropriately sized electrodes and spacing between the electrodes. Bipolar RF energy may be delivered at a maximum of 35 J operating at 1 MHz. Typical RF pulses will be of duration of between 100 and 300ms. Epidermal cooling is accomplished via contact with a cooled window.
