What do hand lotions and hand creams typically contain that supports skin hydration?

Hand lotions and hand creams typically contain a humectant, which is a substance that helps to attract and retain moisture in the skin. Humectants draw water from the atmosphere and deeper layers of the skin into the outer layer, promoting hydration and ensuring that the skin remains soft and supple.

While natural oils can contribute to a product's moisturizing properties by providing a barrier that prevents water loss, they do not have the same moisture-attracting qualities as humectants. Fragrance is often added for sensory appeal but does not directly influence skin hydration. Sunscreen agents serve to protect the skin from UV damage but do not provide moisture. Hence, the humectant stands out as the key component that actively supports skin hydration in hand lotions and creams.
