This laser is used to treat unwanted hair. It is great for those who often get in-grown hairs after shaving or waxing. The best results are seen in patients with light skin and dark hair, however it is also effective in people with darker skin. Blonde and gray hair is not treated effectively since the laser targets the dark pigment in the hair. You will likely need 4 or more treatments, depending on your hair type, density of hair and the area being treated. After the treatment you can expect a slight redness of the area and possibly some mild irritation. As with other lasers, it is important to avoid the sun for a couple of weeks after treatment to prevent post-laser discoloration of the skin.
