Beauty waters continue to be a buzzword in skin care. Many of them work double time—offering a hydrating boost in addition to other benefits. Micellar water removes dirt and makeup without needing to be rinsed. Complexion water tones skin with essential oils and herbal extracts. Rose water helps calm irritated skin. And cactus water fights signs of aging. Another reason to try the trend: they come in a variety of infusions that help brighten, hydrate and soothe or whatever your skin needs.
