"IPL stands for Intense Pulsed Light and is a type of light treatment that uses strong pulses of light to stimulate or treat various issues within the skin,” Sometimes people think IPL is laser as they can do some similar things, but they are not the same. However, the principle of how they work is similar: both direct light at the pigmentation in the hair, causing a burst of heat that damages or kills the cells that cause that hair to grow."
Does IPL hurt?You’ve likely heard varying responses to this question, as the answer really depends on your pain threshold. The sensation is generally compared to that of an elastic-band flick – but the best IPL devices out there work so quickly, you’ll barely have time to register it.
How long does IPL take?Some may see results in as little as three weeks – but again, the exact time will differ from person to person, depending on various factors.
Your hair has a growth phase, a rest phase, and a shedding phase. One of the main reasons why you need to do repeat treatments with IPL or even laser, is because your hairs are not all in the same phase of the cycle at the same time. So to catch all of them, and to get rid of them permanently, you almost have to chase the cycles. This is why IPL treatments are often repeated every four weeks.
