Cream is a viscous semisolid emulsion used for external application to protect, cleanse, or treat skin conditions. There are two main types - water-in-oil creams which prevent moisture evaporation and oil-in-water creams which have a cooling effect. Creams are prepared using a fusion or incorporation method and contain medicinal agents dissolved or dispersed in an oil or water base. They are packaged in air-tight containers like jars or tubes and stored in cool places to maintain stability for their 3-4 week shelf life.
