Intended Use

The Diode Laser Hair Removal System is intended for hair removal, permanent hair reduction on all skin types (Fitzpatrick skin type I-VI), including tanned skin. Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regime.

Device Story

Diode Laser Hair Removal System (HM-DL100) is a surgical laser device for hair removal and permanent hair reduction. System inputs include operator-selected laser energy parameters via a control panel; footswitch state; and sensor data (temperature, humidity, liquid level, flow). A main control module processes these inputs, calculates dew point, and manages a constant current board to drive a semiconductor laser in the handpiece. The handpiece, containing a sapphire contact tip, emits laser energy to the skin. The system includes a cooling subsystem (condenser, cold plate, fans) to maintain operational temperatures. Used in clinical settings by trained operators. Output is laser energy for hair follicle destruction. Benefits include long-term, stable hair reduction.

Clinical Evidence

No clinical data. Bench testing only, including electrical safety (IEC 60601-1, IEC 60601-2-22), EMC (IEC 60601-1-2), laser safety (IEC 60825-1), biocompatibility (ISO 10993-5, ISO 10993-10), and performance testing for spot size and energy output accuracy.

Technological Characteristics

Diode laser (808 nm, Class IV); 1.44 cm2 spot size; 1-120 J/cm2 fluence; 0.5-15 Hz frequency; 5-400 ms pulse duration. Materials: Sapphire contact tip. Cooling: Water circulation, cold plate, fans.
