Milk bath

A milk bath is a bath taken in milk instead of water. Often other scents such as lavender, honey, and essential oils are added. Cleopatra, Elizabeth I of England, Elisabeth of Bavaria, and others have historically acclaimed the beautifying benefits of these baths.

Milk baths use lactic acid, an alpha hydroxy acid, to dissolve the proteins which hold together dead skin cells.

A milk bath for supposed medicinal purposes for a dying child can be seen in the 1931 film Night Nurse.
