Foil razors are electric shavers designed for a close and comfortable shave. They feature a thin, perforated metal foil that covers the cutting blades. This foil captures hair while protecting the skin, making them suitable for sensitive skin types. The blades move back and forth beneath the foil, efficiently cutting hair as the user glides the razor over their face or body. These razors are often preferred for their precision and speed, especially for achieving a clean look. Many models come with additional features like adjustable settings and cleaning stations. Popular brands include Braun and Panasonic, known for their quality and performance.
