A lip protector, also known as a BALM, is a product used to protect and moisturize the lips. It is usually made of waxes, oils, and other ingredients that help to keep the lips hydrated and protected from the elements. Lip protectors come in a variety of forms, such as sticks, tubes, and jars, and can be found in many stores. They are often used to prevent chapped lips, sunburns, and other skin irritations.
