<human>: What is the difference between an ointment and a cream?
<bot>: An ointment is a semi-solid preparation that contains oil, fat, or wax as its base. It is typically used to treat skin conditions such as eczema, acne, and psoriasis. A cream is a thicker version of an ointment, containing more water than an ointment. Creams are usually used for moisturizing and hydrating the skin.
