## IV. Device Description

IPL Hair Removal Device, is an over-the-counter, home-use device for unwanted hair reduction by using Intense Pulsed Light (IPL), and it has been designed 15 models with the same IPL technology for hair removal, which is model LS-T121/12/A/12/12/12/12/12/12/12/12/12/12/12/12/12/12/12/12/12/12/12/12/12/12/12/12 T130/130A/130B, LS-T133/135/136/137, LS-T134/138/139/140. The device works below the skin' s surface and does not involve any cutting or pulling, reducing hair growth with minimal pain.

The device is only powered by the external power adapter and its IPL emission activation is by finger switch.

IPL Hair Removal Device is a Pulsed Light system which emits intense pulsed light (IPL) at a wavelength ranging from 510-1200m and 600-1200mm. The device works on the principles of selective photothermolysis. That is, causing thermal damage to target chromophores by using light of appropriate wavelength in pulses that exceeds the chromophores' thermal relaxation time but sparing normal skin by limiting the pulse width below the thermal relaxation time for skin.

## V. Indications for Use

The IPL Hair Removal Device is an over-the-counter device intended for removal of unwanted body and/or facial hair.
