The Alma Soprano XL works similarly to regular laser machines, in that it gradually heats the hair follicles in the subdermal layer of skin. But rather than beaming light into individual follicles, the Soprano XL uses pulses of infrared diode laser energy to do it. This laser energy doesn’t burn the follicles the usual way, causing the pin prick-like pain; rather, it leaves the skin in relative comfort. Finally, over time Leg Laser Hair Removal is more cost effective than waxing.
