FAQs About Laser Medicine

Laser medicine is relatively new, but it has existed long enough for professionals to have confidence in its safety and effectiveness. Lasers are now routinely used for hair removal, skin rejuvenation and liposuction, among other things. Here are some common questions and answers about laser medicine.

Q: What does laser medicine treat?

A: Lasers have a variety of medical and dental applications. Lasers are used in many types of surgeries, most notably eye surgery and liposuction surgery. Lasers are also used in the beauty industry to rejuvenate skin through resurfacing and remove hair from the body. Low-level lasers are commonly used outside the U.S. as an alternative treatment for many conditions, diseases and symptoms.

Q: How safe is laser medicine?

A: Laser medicine is considered generally safe, although side effects are common and there is a risk of adverse reactions. All medical treatments involve some risk; lasers are no different. Lasers are basically burns, so temporary side effects such as temporary pain, redness, bruising and pigment changes are not unexpected. Scarring is a rare complication of laser treatments. To minimize instances of adverse reactions, check out your health care provider's safety record. Adhering to safety rules and regulations minimizes the risk of adverse reactions.

Q: How long do laser treatments last?

A: The length of time for which laser medicine works depends on many factors, including your body's reaction and the type of treatment received. Depending on your body and your procedure, laser medicine for facial skin can take one to three sessions. Laser hair removal typically takes four to six sessions, and the hair removal is generally not permanent, so repeated sessions after six to eight months are not uncommon.
