You do not need to be concerned about the safety of use. A light-based hair removal device is a Pulsed Light system that emits intense pulsed light (IPL) with a wavelength range of 510-1100nm. The device operates on the principles of selective photothermolysis, which causes thermal damage to target chromophores by using a specific wavelength of light in pulses. These pulses exceed the thermal relaxation time of the chromophores while sparing normal skin by limiting the pulse width below the thermal relaxation time of skin.
