Lasermach Diode laser uses 3 wavelengths of light that has a high abruption rate in melanin. As the melanin heats up it destroys the root and blood flow to the follicle disabling the hair growth permanently. High quality laser hair removal machines such as Lasermach Pro incorporate refrigeration contact cooling to protect the surface of the skin, making the treatment a comfortable, pain-free experience for patients. Diode lasers deliver high frequency, low fluence pulses and can be safely used on all skin types.
