Lotions are applied to external skin with bare hands, a brush, a clean cloth, cotton wool, or gauze. While lotion may be used as a medicine delivery system, many lotions, especially hand lotions and body lotions are meant instead to simply smooth, moisturize and soften the skin.[3] These may be used in anti-aging lotions, which can also be classified as a cosmetic in many cases, and may contain fragrances.

1. Body Lotion
Lotions are applied to external skin with bare hands,
a brush, a clean cloth, cotton wool, or gauze. While
lotion may be used as a medicine delivery system,
many lotions, especially hand lotions and body
lotions are meant instead to simply smooth, moisturize
and soften the skin. These may be used in anti-aging
lotions, which can also be classified as a cosmetic in
many cases, and may contain fragrances. The Food
and Drug Administration voiced concern about
lotions not classified as drugs that advertise anti-
aging or anti-wrinkle properties.
