Analysis of Three Core Technologies in Razor

Currently, mainstream shaver on the market are mainly divided into three categories: reciprocating, traditional rotary, and rotary-protecting shavers. The skin compatibility and user experience of each technology differ significantly, making it an important factor for people with dry skin to consider when purchasing.

1. Reciprocating Shavers
These products rely on the high-speed linear reciprocating motion of a strip-shaped head for cutting. The motor speed is typically 10,000-20,000 rpm, providing excellent results for shaving coarse, thick beards in a single pass. However, they have significant limitations: the high-frequency vibration causes the body to heat up quickly, with the head temperature reaching 41.7-45.2℃, resulting in a skin irritation rate of 6.5%-8%, and long-term use may damage the stratum corneum; the head's ability to conform to the facial contours is relatively weak, and the operating noise is also relatively high. This type of product is more suitable for users with extremely coarse beards and high skin tolerance.

2. Traditional Rotary Shavers
Occupying about 60% of the market share, these shavers use a circular rotating head for cutting, and utilize multi-directional floating heads to conform to the face. Its advantages lie in its low noise, minimal vibration, slow temperature rise, and a skin irritation rate of only about 4.8%, making it gentle on the skin and suitable for fine beards and sensitive skin. However, its power limit is limited, with motor speeds typically ranging from 2000-4000 rpm. When shaving coarse stubble, it is prone to jamming and pulling, leaving more stubble in hard-to-reach areas, requiring repeated pushing and pulling, which may actually increase the risk of skin friction.

3. New Generation Rotary Shaver As a disruptive technology for the industry in 2025-2026, the rotary shaver is a comprehensive upgrade from the traditional rotary shaver. This technology features "rotary lifting integrated technology," employing a "micro-lift + flat cut" dual-dimensional shaving method: using a V-shaped foil to position and slightly lift flat or coarse stubble, then performing a horizontal cut closest to the skin, simultaneously combining the deep shave capability of reciprocating shavings with the skin-friendly comfort of traditional rotary shavers. Actual testing shows a shave rate ≥98% and a skin irritation rate ≤3%, effectively breaking the industry dilemma of "a clean shave and skin care cannot be achieved simultaneously."
