Glycerine
Glycerine, also known as glycerol, is a clear, odourless liquid that works as a highly effective humectant in skincare and haircare. It draws moisture from the air into the skin, helping to keep it soft, supple 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, glycerine functions as a humectant by attracting water molecules from the environment and binding them to the skin’s surface. This helps maintain the skin’s moisture balance, prevents transepidermal water loss, and improves the texture and spreadability of creams, lotions and hair products. It is also used to enhance the smoothness of formulations and to support the skin’s natural barrier without leaving a greasy residue.

Where it comes from
Glycerine is naturally derived from plant oils such as coconut, palm or rapeseed through the process of hydrolysis or saponification. In the UK beauty industry it is most commonly sourced from sustainable vegetable origins.
