IPL stands for Intense Pulsed Light technology. IPL hair removal devices apply very gentle pulses of light to the hair root. This makes the hair go into its resting phase: the hair you have falls out, and gradually your body grows less hair in that area.
WE recommend about 6 IPL sessions to get rid of 70% of hair permanently. Also the way IPL works by killing the follicle mans that in grown hairs will no longer be a problem. There is no need to grow out your hair before treatment as it is necessary to shave (NOT WAX OR PLUCK) on the day or the day before treatment.
