The key to successful diode laser hair removal is the deliverance of high energy into the skin. The energy is selectively absorbed by the melanin surrounding the hair follicle whilst not impacting the surrounding tissue.
Diode lasers use a single wavelength 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 The Primelase HR and The Elysion incorporate crystal freeze refrigeration contact cooling (+5ºC) 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.
