IPL is called Intense Pulse Light, it is different from a regular laser treatment per se.  It is mainly for bringing up your pigment to the surface of the skin.  Sometimes you may not see the results right away, give it a few days or even a week depending on your skin.  We use the M22 machine here which is highly effective and sworn by many doctors as the best.  If you are unsure that this is the proper treatment for you then have a free consultation first.
