When using an electric shaver, it is necessary to stretch the skin with one hand before washing your face and shave along the direction of beard growth to avoid excessive force. If using a mesh type electric shaver, keep the shaver perpendicular to the face, hold the electric shaver at a 90 degree angle, and make forward and backward reciprocating movements; If using a rotary shaver, it is necessary to move the shaver in a circular motion and combine some up and down strokes. Clean the shaver after each use to maintain hygiene and performance.
