Using your Lux Lip Care device is easy. First, clean your lips gently with a mild cleanser and pat them dry. Then, turn on the device and hold it close to your lips for the recommended time, usually a few minutes each day. You can use it while relaxing at home. As for precautions, don't use the device if you have any open wounds or infections on your lips. Also, avoid direct eye contact with the lights. To maintain your device, wipe it with a soft, dry cloth after each use. Store it in a cool, dry place away from direct sunlight. With regular use, you'll notice a significant improvement in the appearance of your lips.
