Does hyaluronic acid dehydrate skin?
No, hyaluronic acid is a humectant that draws moisture into the skin rather than removing it. This misconception may stem from its name, but published evidence does not support skin dehydration concerns.
Why is hyaluronic acid in skincare?
It's a humectant that helps skin retain moisture, making it a foundation ingredient in hydrating products. Hyaluronic acid has been extensively studied and is one of the most widely used ingredients in modern skincare.
