What Is a Foil Shaver?
Foil shavers are electric shavers with a thin, perforated piece of metal between the cutting surface and the blades. The metal part is called the foil, and it helps protect sensitive skin from the blades of the razor.
Foil shavers are one of the two most popular types of electric shavers. The other type is the rotary shaver, which uses independent heads that rotate to cut and move with the contours of the face. Rotary shavers tend to provide a closer shave but are rougher on skin. Foil shavers are the best choice for people who shave every day, have sensitive skin or have fine hair.
