Laser hair removal is a relatively new technology that has become increasingly popular in recent years. The procedure uses a concentrated beam of light to remove unwanted hair from the body. While laser hair removal can be an effective way to permanent hair reduction, it is not without its side effects. One common side effect of laser hair removal is that it can cause the treated area to become dry and irritated. This can lead to the formation of scabs and crusts on the skin. In some cases, laser hair removal can also cause the treated area to become red and swollen.
