A lotion is a low- to medium-viscosity topical preparation intended for application to unbroken skin. Lotions are applied to external skin with bare hands, a clean cloth, cotton wool or gauze Moisturizers prevent and treat dry skin, protect sensitive skin, improve skin tone and texture, and mask imperfections. Naturally occurring skin lipids and sterols, as well as artificial or natural oils, humectants, emollients, lubricants, etc., may be part of the composition of body lotion. They are usually available as commercial products for cosmetic and therapeutic uses. They can be used to prevent the skin from becoming too dry or oily. Lotions also increase the skin’s ability to attract, hold and distribute moisture.
