Emollients are moisturizing agents that play a vital role in skincare by softening and soothing the skin. They work by filling in the spaces between skin cells, smoothing out rough texture, and providing a protective layer that locks in moisture. This not only helps to keep the skin hydrated but also makes it feel softer and more pliable. Emollients are particularly beneficial for dry, rough, or flaky skin, as they help to repair the skin's natural barrier, promoting a healthy, hydrated complexion.
