The light energy is absorbed disproportionately by the concentration of pigment which forms the unwanted lesion. This selective delivery of laser energy destroys the excess pigment and fades the lesion, but remarkably leaves the surrounding tissue unaffected. The number of treatment sessions required varies from patient to patient, but typically two to four sessions are needed. Each session usually lasts between 15 and 30 minutes, but again will vary depending on your individual needs. Some people feel a slight discomfort with each laser pulse, describing the sensation as similar to having an elastic band snapped against the skin. Ask your provider what you should expect. You will be able to resume normal activities after each session, but you may be given specific advice, such as avoiding sun or abrasive skin cleansers on treated skin for a few days. After the treatment, a cool compress or gel pack may be applied. If you do have any redness or swelling after treatment, this should resolve in a couple of hours. Permanent side effects are rare but should be discussed with your provider.

You should always follow specific instructions from your healthcare provider.
