A natural pairing, now get a Silk'n Trim alongside your Flash&Go Express Device! First, use the trimmer to shear hair in awkward, hard-to-reach areas or delicate areas such as the face. The trimmer can also be used in areas that you don't necessarily want to shave. After the hair is cropped, you can then begin your hair removal treatment. Follow the hair removal schedule and remember to trim prior to each treatment.
