Surgery using a laser


A laser is a light beam that can be focused on a very small area. The laser heats 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 , , sunspots, and tattoos
  • Reduce the appearance of 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
  • Bleeding
  • Problem not going away
  • Infection
  • Pain
  • Scarring
  • 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 health care provider about what you can expect. 

You may need to keep your skin moisturized and out of the sun after treatment.

Outlook (Prognosis)

Recovery time depends on the surgery and your overall health. Ask your health care provider before surgery how much recovery time you will need.
