Why are hydrating ingredients important for dry skin?

Hydrating ingredients are essential for dry skin primarily because they have the ability to attract and retain moisture, which is crucial in preventing symptoms like flakiness and tightness. Dry skin occurs when the skin lacks sufficient water content, leading to discomfort and a compromised skin barrier. Ingredients such as hyaluronic acid, glycerin, and aloe vera work by drawing moisture from the environment or deeper layers of the skin and holding it in place. This process helps restore the skin's natural hydration levels, resulting in a more supple and smooth texture.

The other options do not directly address the primary concern of dry skin. While enhancing color, removing excess oil, or providing sun protection are important benefits in skincare, they do not target the fundamental issue of dehydration. Hydrating ingredients specifically focus on maintaining moisture balance, which is vital for overall skin health and comfort.
