Which of the following can help to lock in moisture on the skin?

Emollients are substances that help to lock in moisture on the skin by creating a protective barrier. They work by filling the spaces between skin cells and preventing water loss. This is essential for maintaining skin hydration, particularly in dry or compromised skin conditions. Emollients not only improve the skin’s texture but also contribute to its elasticity and overall appearance.

In contrast, astringents are designed to tighten and constrict skin, often used in products intended to reduce excess oil or the appearance of pores, which does not promote moisture retention. Exfoliators function by removing dead skin cells from the surface of the skin, enhancing product absorption but not by holding moisture in. Antiseptics are used primarily to reduce infections and cleanse the skin, but they do not address moisture levels or contribute to hydration.
