Lotion vs. Viscosity — What's the Difference?

A lotion is a low-viscosity topical preparation intended for application to the skin. By contrast, creams and gels have higher viscosity, typically due to lower water content.

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water.Viscosity can be conceptualized as quantifying the internal frictional force that arises between adjacent layers of fluid that are in relative motion.

A protective or restorative liquid or cream applied to the skin.

The condition or property of being viscous.

A low- to medium-viscosity topical preparation intended for application to unbroken skin.

(Physics) Coefficient of viscosity.

(archaic) A washing, especially of the skin for the purpose of beautification.

(uncountable) The state of being viscous.

(transitive) To cover or treat with a lotion.

A quantity expressing the magnitude of internal friction in a fluid, as measured by the force per unit area resisting uniform flow.

A washing, especially of the skin for the purpose of rendering it fair.

A tendency to prolong interpersonal encounters.

A liquid preparation for bathing the skin, or an injured or diseased part, either for a medicinal purpose, or for improving its appearance.

The quality or state of being viscous.

Any of various cosmetic preparations that are applied to the skin

A property possessed by a viscous fluid, being a resistance to the forces causing a fluid to flow, caused by interactions between the molecules of the fluid and between the fluid and the walls of the conduit through which it moves; also, a measure of such a property.

Liquid preparation having a soothing or antiseptic or medicinal action when applied to the skin;

Resistance of a liquid to sheer forces (and hence to flow)
