What is an important ingredient commonly found in hand lotions and creams?

Humectants are crucial ingredients in hand lotions and creams because they are designed to attract moisture to the skin and retain it. This capability is particularly important for maintaining hydration levels, especially in products aimed at treating dry or damaged skin. Common humectants like glycerin, hyaluronic acid, and urea work by drawing water from the air into the skin or by holding onto water within the skin layers.

While exfoliants can help remove dead skin cells, they are not typically a mainstay ingredient in moisturizers, as the primary function of lotions and creams is to hydrate and protect the skin rather than to exfoliate. Fragrances are often added to enhance the sensory experience of using a lotion, but they do not contribute to the moisturizing properties. Alcohol, particularly in high concentrations, can actually dry out the skin, although some lower concentrations of certain types may serve different purposes in formulations. Thus, humectants are essential for effective moisturizing, making them a common and vital component in hand lotions and creams.
