A facial mask is a skincare product designed to be applied to the face for various benefits. These masks can hydrate, cleanse, exfoliate, or treat specific skin concerns like acne or aging. They come in different forms, including sheets, creams, gels, and clay, and are typically left on the skin for a set period before being removed or rinsed off. Facial masks often contain active ingredients such as hyaluronic acid, charcoal, or vitamin C to enhance their effectiveness. They are commonly used in beauty routines and can be found in both professional spa treatments and at-home applications, making them accessible for various skin types and needs.
