An electric razor runs on electricity to provide closest and smoothest shave without water. It is quick and totally safe. Depending on the formation and style, it can either have rotary blade technology or foil technology. Typically, a rotary blade electric shaver would have three motorized circular blades in a triangular pattern, and while shaving with them, you need to rotate the razor slowly on your face as you do while applying a lotion.
When in the foil type electric razor, the tiny knives are hidden under the metallic rectangular foil that raises the hair to direct towards vibrating knives for a close shave. Though both types of it have the same usage, rotary are suitable for cheeks while foil work good on chin. You can choose to have both for perfect shaving experience.
