Glycerin
Glycerin, also known as glycerol, is a clear, odourless liquid that acts as a powerful humectant in skincare and haircare. It draws moisture from the air and holds it in the skin, helping to keep products and formulas feeling silky and hydrated. You'll find it in everything from moisturisers and serums to lip balms and shampoos.
How it works in skincare
In cosmetics and skincare, glycerin works by attracting water molecules to the upper layers of the skin through humectant action, preventing moisture loss and maintaining the skin’s natural barrier. It improves the texture of formulations, giving creams a smooth, non-greasy feel while enhancing spreadability and preserving the product’s softness over time. Because it is compatible with most other ingredients, it is widely used across both premium and everyday British beauty products.
