It's recommended that you apply a generous layer of a skin cream containing lidocaine over the area to be subjected to laser hair removal. If the doctor doesn't provide it, it's simple enough to buy it over-the-counter, and it tends to be inexpensive.
You should always wear special goggles when getting laser hair removal done to any part of your body, in order to protect your eyes from the laser light. Laser light is very strong, and can be damaging to the retina. Even if the laser is pointed away from your face, accidents do happen.
Laser hair removal basically involves damaging or destroying the follicle of the unwanted hairs. When you get the treatment, the affected hair might not fall away immediately; however, it will soon afterward, and that particular hair will never grow back.
