Abstract
A method of hair depilation using an Nd:YAG laser which causes local heating at the hair bulb due to the absorption of the oxyhemoglobin contained in the capillaries. The Nd:YAG laser operates at 1060 nanometers. Each pulse is a special pulse having a first portion and a second portion, where power output in the first portion is 20 times greater than power output in the second portion. That way, the first portion of each pulse is used to quickly heat up the tissue to a damaging temperature, and the second portion maintains that temperature to cause hair removal for the tissue.
Claims6
A method of hair depilation and prevention of hair regrowth, comprising:
- applying pulses of radiation to a skin of a patient, at a pulse length of from 100 to 500 msec, the pulses of radiation being emitted by a laser source with a wavelength ranging from 500 to 1500 nm and having a distribution of energy such that each pulse includes a first portion and a second portion,
- wherein the first portion of said each pulse comprises less than 20% of the pulse length has more than 20% of a total energy of said each pulse.
