First things first: what is it?

Glycerin, also called glycerol, is a humectant: an ingredient that attracts water.

What does it do?

Moisture support

It is used as a skin-conditioning humectant and helps provide smoothness and lubrication.

Science or just a good story?

Its moisture-related function is established in cosmetic formulation. That function does not tell us how a whole moisturiser will feel or perform.
