DESCRIPTION
Glycerin is a humectant, which means it pulls water toward itself - on skin that translates to holding moisture where you put it. It is one of the oldest and least glamorous ingredients in a pharmacy, and it is in half the moisturisers on the shelf. Used neat it is thick and syrupy, so most people dilute it: a little in rosewater makes a simple hydrating toner, and a few drops in a bowl of warm water makes a hand soak. It also has a long history in home preparations and craft use. 200ml, clear and odourless.
