Hydrating Agents
Hydrating agents are ingredients that help draw moisture into the skin or hair and lock it in place, leaving it feeling soft, supple and comfortable. They are a staple in UK moisturisers, serums, masks and hair conditioners, making dry or dehydrated skin and hair feel instantly quenched.
How it works in skincare
In cosmetics and skincare, hydrating agents function primarily by attracting water molecules from the atmosphere or from deeper layers of the skin and binding them within the outer layers. Humectants such as glycerin, hyaluronic acid and sorbitol sit on the surface or within the stratum corneum, creating a moisture reservoir that prevents transepidermal water loss and maintains optimal hydration levels for a smoother, plumper appearance.
