Like many other pharmaceutical preparations, they frequently contain preservatives and may also contain aromatic substances and dyes to enhance patient acceptance. Although there is generally no agreed-upon pharmaceutical definition for creams, they are very much like ointments in their use.

When applied to the skin, creams feel soft and supple and spread easily.
