Laser Hair Removal is a safe and effective way to remove unwanted hair from various places on the body. Most patients describe the procedure like a rubber band snapping against their skin. If you are sensitive to pain, discuss with your physician prior to the procedure. Topical anesthesia can be provided to help those with sensitive skin.  As hair grows in different stages: growing, resting and shedding and all of the hair isn't on the same stage at any given time, multiple sessions are needed to get the hair in the growing phase, waiting 3 to 8 weeks between treatments.
