A facial is a procedure involving a variety of skin treatments, including: steam, exfoliation, extraction, creams, lotions, facial masks, peels, and massage. They are normally performed in beauty salons but are also a common spa treatment. There are different kinds of masks (e.g. cactus, cucumber, etc.) for different purposes: deep-cleansing, by penetrating the pores; healing acne scars or hyper-pigmentation; brightening, for a gradual illumination of the skin tone. Some masks are designed to dry or solidify on the face, almost like plaster; others just remain wet. The perceived effects of a facial mask treatment include revitalizing, healing, or refreshing; and, may yield temporary or long-term benefits (depending on environmental, dietary, and other skincare factors).
