What is the function of hyaluronic acid in skincare products?

Hyaluronic acid is a powerful humectant, which means its primary function in skincare products is to attract and retain moisture within the skin. This ability to hold water molecules makes it incredibly effective for hydrating the skin and giving it a plumper, more youthful appearance. When applied, hyaluronic acid can draw moisture from the environment into the skin, helping to maintain optimal hydration levels. This is particularly beneficial for individuals with dry or dehydrated skin, as it can help to reduce the appearance of fine lines and wrinkles caused by dryness.

In contrast to functions like reducing acne breakouts or evening skin tone, hyaluronic acid does not directly address these concerns. While it may provide some indirect benefits in overall skin health, its main role is fundamentally rooted in moisture retention. Additionally, sun protection is not within its scope, as hyaluronic acid does not provide any UV filtering properties. Thus, its key contribution to skincare formulations is its ability to support skin hydration and plumpness, making it a highly valued ingredient in many skincare products.
