Women would often prepare their faces with beauty masks prior to applying makeup. One recipe called for the application of sweat from sheep's wool (lanolin) to the face before bedtime,[14] emitting a stench often criticized by men.[15] Other ingredients included juice, seeds, horns, excrement,[16] honey, plants, placenta, marrow, vinegar, bile, animal urine, sulfur, vinegar,[6] eggs, myrrh, incense, frankincense,[17] ground oyster shells,[18] onions with poultry fat, white lead, and barley with vetch. Bathing in asses’ milk was an expensive treatment that worked like a chemical peel and was used by wealthy women such as Cleopatra VII and Poppaea Sabina.[19]
