50ml Carbon Dye High Viscosity Gel Formula for Laser and IPL Permanent Hair Removal Machines Carbon dye is used to increase the pigment in hair which helps laser and IPL radiation convert to heat. This heat is what cauterizes and thermally desiccates the hair follicle unit which permanently disables the organ (thereby preventing future hair growth). The use of carbon dye increases laser and IPL hair removal results by over 300% in clinical testing.
