What is a primary benefit of using hyaluronic acid in skin care?

It brightens the skin tone
It helps hydrate the skin by retaining moisture
It reduces the appearance of scars
It eliminates dark circles under the eyes

The correct answer is: It helps hydrate the skin by retaining moisture

The primary benefit of using hyaluronic acid in skin care is its ability to help hydrate the skin by retaining moisture. Hyaluronic acid is a naturally occurring substance in the body that has an incredible capacity to hold water—up to 1,000 times its weight. This characteristic makes it an excellent ingredient for delivering hydration, plumping the skin, and improving overall texture. By retaining moisture, hyaluronic acid assists in maintaining skin elasticity and can lead to a more youthful appearance, making it a popular choice in many skincare products. While some of the other options may touch on skin concerns, they do not capture the primary function of hyaluronic acid. For instance, improving skin tone or addressing concerns like scars and dark circles may involve different ingredients or treatments. Therefore, the hydration aspect stands out as the most significant benefit of hyaluronic acid in skincare formulations.
