What can glycerin help with?
Dry skin
In two randomised, double-blind studies, glycerin in a cream increased skin hydration.[1][2] A third study showed that glycerin helps the skin regain moisture after being dried out by a detergent.[3]
Dry hair
Glycerin is also used in shampoo and conditioner, where it binds moisture in the hair.
How it works
How to use it

Frequently asked questions
Yes, they are the same substance. Glycerol is the chemical name, while glycerin is the name used in skincare and on the ingredient list (INCI: Glycerin).
Glycerin is usually made from vegetable oils and fats, such as coconut, palm or rapeseed oil, when the fat is broken down. It can also be made from animal fat or produced synthetically. The substance is the same, regardless of where it comes from.
Glycerin is the INCI name for glycerol, the name used on ingredient lists throughout the EU. Ingredients are generally listed in descending order of quantity, but below 1 % the order may vary. You cannot see the exact amount on the list.
In randomised, double-blind studies, creams with glycerin gave skin more moisture than comparable creams without glycerin, both for dry skin and atopic eczema. Glycerin also helped the skin regain moisture after a detergent had dried it out. A review article describes how the skin itself uses glycerol to retain moisture.
