Do I need to shave before using this product?

Yes, you should shave the desired areas before using your handset. A close to skin shave is best recommended. The goal is for the light energy to reach the hair follicle as quickly as possible, so shaving beforehand is essential to achieve the best results. The hair follicle does need to be intact for IPL to be effective. This means no waxing, plucking, threading, epilating etc.
