Lip skincare products are designed to protect and hydrate the lips, which are prone to dryness and cracking. They typically come in the form of balms, oils, and masks, and contain ingredients such as shea butter, vitamin E, and jojoba oil, which help to moisturize and nourish the lips. Lip skincare products should be applied regularly, especially during colder months or when exposed to harsh environmental conditions, to keep the lips smooth and healthy.
