Lasers have been used for many years for a variety of medical cosmetic procedures including treatment of facial and leg veins, age spots and smoothing fine lines on the face. The laser energy is transformed into heat, which can disable the follicle leaving the surrounding skin unchanged. Depending on the amount of hair and area treated, the procedure varies from patient to patient. Generally, the treatment will include safety eyewear to protect the patient's eyes during the procedure from the laser light. A small hand piece will be used to deliver the laser light. Most experience little discomfort at the treatment site. The sensation and the degree of discomfort varies with each person. In some cases, topical anesthesia is an option.
