What is the main purpose of a hydrating serum?

The primary function of a hydrating serum is to provide moisture and enhance skin hydration levels. These serums typically contain a blend of water-binding ingredients such as hyaluronic acid, glycerin, and various botanical extracts that attract moisture from the environment and penetrate the skin deeply. By delivering these essential hydrating components, the serum helps maintain the skin's moisture balance, improve elasticity, and create a plump, youthful appearance.

Hydrating serums are particularly beneficial for individuals with dry or dehydrated skin, but they can also be used effectively by those with oily or combination skin types, as hydration is crucial for overall skin health. This approach helps to prevent signs of aging and supports an effective skincare routine where moisture is adequately replenished. Thus, option A accurately reflects the primary purpose of a hydrating serum.
