Just before the procedure, your hair that will be undergoing treatment will be trimmed to a few millimetres above the skin surface. The laser equipment will be adjusted according to the color, thickness, and location of your hair being treated as well as your skin color. Depending on the type of laser or light source used, you and the technician will need to wear appropriate eye protection. It will also be necessary to protect the outer layers of your skin with a cold gel or special cooling device. This will help the laser light penetrate the skin. Next, the technician will give a pulse of light to the treatment area and watch the area for several minutes to make sure the best settings were used and to check for bad reactions. When the procedure is completed, you may schedule your next treatment six weeks later. You’ll get treatments until hair growing stops.
Hair removal via laser can cause temporary irritation. You may also notice slight redness and swelling at the treated area. Still, these effects are minor. They are often the same effects you might notice after other types of hair removal, such as waxing.
