Lotions are mainly intended to help the skin, but it can also harm your skin. Christina Marino, who practices at Johns Hopkins Community Physicians, has conducted much research on this aspect. Moisturizers contain ingredients that are either occlusive or humectant. Occlusive agents are used to help block the loss of water from the skin. Humectant agents are used to attract water to the skin. With significant water exposure to the skin, it can cause the loss of soluble natural factors in your skin. With persistent moisturization to the skin, from exposure to water will result in: penetration of foreign objects, it may contribute to an allergic reaction, or irritant contact dermatitis. Changes in the skins normal ecological environment in or on the skin, can support the overgrowth of pathological organisms. Lotions contain 65-85% of water. Water acts as an agent to disperse the active and inactive ingredients in the lotion. A high water content also serves as a way for the absorption of some components and evaporation of the moisturizer. Water acts as a temporary hydration agent.
