An emollient, often known as a moisturizer, is a cosmetic preparation that lubricates, protects, and moisturizes the skin. The sebum that healthy skin produces typically carries out these tasks. "Emollient" comes from the Latin verb "mollie," which means to soften. The petrolatum is white.

Because of their vital role in nourishing and shielding the skin, moisturizers are an indispensable part of any skincare routine.
