What is the main benefit of using hyaluronic acid in skincare products?

The main benefit of using hyaluronic acid in skincare products is its powerful ability to provide hydration. Hyaluronic acid is a naturally occurring substance in the body known for its capacity to hold water—up to 1,000 times its weight in water—which makes it incredibly effective for maintaining skin moisture levels.

When applied topically, hyaluronic acid helps to bind water to the skin, resulting in a plump, youthful, and hydrated appearance. This hydrating effect can improve the skin's elasticity, reduce the appearance of fine lines and wrinkles, and enhance overall skin texture.

While brightening, exfoliating, and oil reduction are important aspects of skincare, they are not the primary functions of hyaluronic acid. Other ingredients typically address those concerns; for instance, vitamin C is often used for brightening, alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs) for exfoliation, and specific formulations like salicylic acid for oil reduction.
