SmoothPro+ will not hurt your eyes. The safety system prevents flashing when the device is not fully in contact with the skin. Be sure to make good skin contact to avoid unnecessary scattered light and never use SmoothPro+ in the area around your eyes or for treating your eyebrows. You may wear goggles during use. We recommend using SmoothPro+ in a well-lit room, to reduce the perceived brightness of the flash.
