Laser Hair Removal Really Turns Up The Heat
Since its arrival in the 1990s, laser hair removal has become one of the most popular cosmetic procedures in the world. It targets specific areas of a person's body with laser pulses, the energy of which is absorbed by the melanin molecules in hairs. This essentially overheats and damages the cells in the hair's follicle, preventing it from regrowing. The laser light has to be of an optimal wavelength to prevent its absorption by other molecules in the surrounding skin, which could cause burns.
