What skin concern is hyaluronic acid primarily used to address?

Hyaluronic acid is primarily used to address dryness in the skin. This ingredient is a powerful humectant, meaning it has the ability to attract and retain moisture from the environment. When applied to the skin, hyaluronic acid binds water molecules, helping to keep the skin hydrated and plump. This makes it particularly effective for individuals experiencing dry skin, as it can significantly improve moisture levels and enhance the overall texture and appearance of the skin.

While it's true that hyaluronic acid can also be beneficial in reducing the appearance of fine lines and wrinkles, as well as improving skin elasticity by providing hydration, its primary function is to combat dryness. The other options, such as oily skin or uneven skin tone, do not align as closely with the core properties and uses of hyaluronic acid.
