The cleansing agents gently lift dirt and makeup from the skin, without the need to rub the face. Indeed, the fact that no rinsing is even required makes this ideal for people living in hard water areas (that's most of England, then!).
400ml provides 200 uses, and is perfume free, making it suitable even for sensitive skin. Garnier Micellar Water is hypoallergenic, and designed for use on the face, eyes and lips (dermatologically and opthalmologically tested).
