With the Philips Lumea Advanced BRI923/00, you're ensured of the correct use of the IPL-device. Via an app, you'll receive personal guidance with each treatment. You can use the various windows for different parts of your body, face, or bikini line. For example, use the largest attachment for your legs and armpits. You can use the medium window for your face and the smallest one for your bikini line. The built-in skin sensor constantly measures the skin tone and adjusts the light intensity accordingly. This way, you can prevent flashes on sensitive parts of your skin, a mole, for example. In addition, you'll receive a precision trimmer to remove small hairs. You can use this to shape your eyebrows or remove downy hair from your sideburns.
