Developed in association with a leading dermatologist, the i-LIGHT is fast, painless and highly effective. Using professional IPL (Intense Pulsed Light) technology - the same used in professional hair removal clinics - it safely removes hair for an ultra silky smooth feeling that can last for up to 12 weeks. And as it's the first IPL with a multi-flash mode, this makes it one of the fastest IPL methods of long lasting hair removal.
