If you want a smooth, clean shave, you need an electric shaver. They are designed to glide across the skin, lifting hair and cutting it closely. They’re generally used every day or two. Electric shavers have either rotary or foil heads.
Rotary heads have multiple discs that spin quickly. These are usually flexible, allowing you to easily shave the contours of your face.
On foil heads the blades oscillate, meaning they move back and forth. They are generally rectangular in shape.
