Hello Maria: Laser hair removal does not cause cancer because it uses non-ionizing radiation. The United States Department of Labor defines non-ionizing radiation as "a series of energy waves composed of oscillating electric and magnetic fields traveling at the speed of light." This type of radiation produces intense heat but does not cause cell mutation. In fact, non-ionizing radiation surrounds us every day. Sources of this type of radiation include ultraviolet light, visible light, power lines, cellular phones and many household appliances. The lasers used for hair removal produce much the same type of heat as an ordinary light bulb.
Hope this helps! See you soon... Thank you!
