Like lasers, IPL goes below the surface to a deeper layer of skin called the dermis. Short pulses of light heat and destroy cells to start renewing your skin. Unlike a laser, IPL uses a broad spectrum of light that can treat different kinds of  blemishes at the same time. The treatment is usually painful, so ask your doctor how you can be more comfortable.
How long you are off work depends on your occupation. If you do clerical work (i.e. stockbroker, teacher, or programmer), you can return to work when you feel up to it. This usually takes about two to three days. Do not go to work for three weeks if you do manual labor (i.e. entertainer, truck driver or personal trainer). Regardless of your employment, do not lift anything weighing more than five pounds for three weeks.
