What is the main purpose of hyaluronic acid in skincare products?

Hyaluronic acid is primarily known for its exceptional ability to hydrate the skin and retain moisture. This naturally occurring substance can hold up to 1,000 times its weight in water, making it an incredibly effective humectant. When included in skincare products, hyaluronic acid draws moisture from the environment into the skin, helping to maintain hydration levels, improve skin elasticity, and create a plump appearance.

While other options like preventing acne, promoting collagen production, and lightening skin tone are important aspects of various skincare acts, they do not represent the primary function of hyaluronic acid. Its focus on hydration is what sets it apart as a key ingredient in many moisturizers and serums, especially for those looking to combat dryness and improve overall skin texture.
