A laser hair removal device is a handheld device designed to remove unwanted hair using laser technology. It works by emitting concentrated light that targets the pigment in hair follicles, heating and disabling them to prevent future hair growth. These devices are typically used on areas like the legs, arms, face, and bikini line. Many at-home models offer adjustable settings for different skin types and hair colors, providing a convenient, long-lasting solution for hair removal.
