The Professional Hair Removal Device uses intense pulsed light to neutralize hair follicles and break the cycle of hair growth. Each pulse of light targets the melanin deep inside the hair follicle, causing the hair to fall out naturally and prevents new hair from growing back. Ideal for hairline, cheek, lip, back, armpit, chest, arm, abdomen, bikini line, thigh and calves. Please note: This device is not suitable for those with dark skin (dark brown to black) and is not effective on white, gray, red or light blonde hair.
