Ask a question


Intense pulsed light is a method of depilation used in aesthetic medicine. It also serves to slow signs of aging. Ranging in spectrum from 400 to 1,400 nanometers, intense pulsed light warms chromophores, which leads to either their disappearance or their modification. Melanin and oxyhemoglobin are notable chromophores. Every chromophore has a particular wave length.
