laser hair removal
photoepilation hair reduction treatment in which a laser beam is pulsed on the skin using one wavelength at a time, impairing hair growth; an intense pulse of electromagnetic radiation.
photoepilation
also known as Intense Pulsed Light (IPL); permanent hair removal treatment that uses intense light to destroy the growth cells of the hair follicles.
pilosebaceous unit
the hair unit that contains the hair follicle and appendages: the hair root, bulb, dermal papilla, sebaceous appendage, and arrector pili muscle.
sugaring
