Lip masks are specialized skincare products designed to hydrate and nourish the lips. They often come in the form of sheets or gels that are applied directly to the lips for a set period, usually around 10 to 20 minutes. These masks are infused with ingredients like hyaluronic acid, shea butter, and vitamin E to help lock in moisture and improve the overall texture of the lips. Using a lip mask can be beneficial for those with dry or chapped lips, especially in harsh weather conditions. They can provide a quick boost of hydration and are often used as part of a nighttime skincare routine. Regular use may lead to softer, smoother lips over time.
