With the Philips Lumea Advanced BRI923 / 00 you can be sure that you are using the IPL device in the right way. Through an app you receive personal guidance with every treatment. You use the different windows on different parts of your body, face or bikini line. Use the large attachment for legs and armpits. Use the middle window on your face and the smallest window for your bikini line. The built-in skin sensor constantly measures the skin color and adjusts the light intensity accordingly. This will prevent you from releasing flashes on vulnerable parts of the skin, such as moles. In addition, you receive a precision trimmer to shave away small hairs. Bring your eyebrows into shape or remove your hairs under your sideburns.
