Laser surgery for the skin
Laser surgery uses laser light to remove diseased tissues or treat bleeding blood vessels. Laser surgery may also be used to restore the skin and reduce wrinkles, sunspots, tattoos, or birthmarks.
Surgery using a laser
A laser is a light beam that can be focused on a very small area. The laser heats the cells in the area being treated until they "burst."
There are several types of lasers. Each laser has specific uses. The color of the light beam used is directly related to the type of surgery being performed and the color of the tissue being treated.
Why the Procedure Is Performed
Laser surgery can be used to:
- Close small blood vessels to reduce blood loss
- Remove warts, moles, sunspots, and tattoos
- Reduce skin wrinkles, scars, and other skin blemishes
- Remove dilated blood vessels from the face
- Remove hair
- Remove skin cells that could turn into cancer
Possible risks of laser surgery include:
- Cold sores if herpes simplex virus is already present
- Problem not going away
- Skin color changes
Some laser surgery is done when you are asleep and pain free (general anesthesia). Talk to your health care provider about risks of laser surgery.
After the Procedure
The success of laser surgery depends on the condition being treated. Talk to your provider about what you can expect.
Also discuss with your provider, skin care following treatment. You may need to keep your skin moisturized and out of the sun.
Recovery time depends on the surgery and your overall health. Ask your provider before treatment how much recovery time you will need. Also ask about how many treatments you'll need to achieve your goal.
