During an initial consultation, the physician determines the ideal laser device to use and provides a prediction of the outcome of the treatment. The patient’s medical history will be reviewed, including existing medical conditions and past medical or cosmetic procedures, and a list of current medications will be taken. A physical examination will also be performed to check for any underlying conditions that may complicate surgery. Patients may wish to consult a dermatologist, a specialist in skin conditions.

A spot test in a small site is generally done to assess the patient’s response to laser surgery and to determine the setting for laser treatment. The best sites for this test are in low-visibility areas with the same skin type as the area intended for treatment.

Patients who are scheduled to undergo laser surgery should follow any preparatory instruction given by their surgeon. As with any form of surgery, this may include dietary restrictions and taking certain medications for several hours or days prior to the procedure. For instance, those with a history of herpes simplex virus may be required to take antiviral medications to prevent a breakout following surgery. A patient should also make plans for postsurgical care and help, if needed.
