Alternative Names

Surgery using a laser

Description

A laser is a light beam that can be focused on a very small area. The laser heats specific 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:

• Remove warts, moles, sunspots, and tattoos
• Reduce skin wrinkles, scars, and other skin blemishes
• Remove dilated blood vessels and redness
• Remove hair
• Remove skin cells that could turn into cancer
• Shrink surface leg veins
• Improve skin texture and cellulite
• Improve loose skin from aging

Risks

Possible risks of laser surgery include:

• Pain, bruising, or swelling
• Blisters, burns, or scarring
• Infections
• Discoloration of the skin
• Cold sores
• Problem not going away

Most laser surgery for the skin is done while you are awake. Talk to your health care provider about the 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.

Outlook (Prognosis)

Recovery time depends on the type of treatment 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.
