Electric shavers with automatic stubble type detection

Stubble detection

— the electric shaver's head features a unique sensor that detects bristle density and stiffness. Through the auto stubble function, the shaver's motor adjusts power based on specific skin requirements. This feature enables efficient one-pass shaving, even for thicker stubble. As the shaving head transitions from dense to moderate bristles, the motor power decreases automatically. This not only conserves battery life but also provides a gentler experience for the skin.
