Because facial pores will expand slightly after washing your face, it is best to shave before washing your face. After getting up in the morning before washing your face is an ideal shaving time.2. Because the beard grows downwards, the reverse shaving can make the scum stand upright and easy to shave, so when shaving, it should be reversed from the bottom to the top.3. When shaving, use your hands to tighten the skin. Don't push the cutter head vigorously. You can clean the scum by gently sliding over the arc area. If the blade is deformed and damaged, it should not be used again, otherwise there will be a danger of injury.4. The cutter head must be close to the skin to achieve the best results. When in use, the angle between the razor and the skin should be kept at ninety degrees, so that the cutter head can approach the beard without hindrance to achieve the best shaving effect.
