Modern medicine has found many important uses for lasers in treating all sorts of problems with skin, hair, nails, and other parts of the body. These advancements in dermatology have made procedures like laser hair removal extremely safe. For example, before, only people with dark hair and light skin could use the treatment, but the technology can now be safely used for any skin tone. The procedure is carried out carefully in any case and under the supervision of a dermatologist.
