Firstly, it hydrates skin. Glycerin is emollient, humectant and occlusive. Put simply, it quickly penetrates the epidermis where it absorbs several times its weight in water and imitates our skin's natural, hydrating process - something that lessens with age. It traps water in the epidermis by forming an occlusive barrier, meaning our skin doesn't dry out.
Secondly, it's an anti-ageing powerhouse. Glycerin has surfactant properties that smooth skin whilst keeping it well-hydrated. Its moisturising action keeps skin supple and comfortable for longer. So you can kiss goodbye to tight skin!
Thirdly, it repairs skin. Glycerin nurses skin back to health by helping the epidermis to synthesise lipids. It improves skin tone and leaves it feeling wonderfully soft.
Finally, it protects us. Glycerin protects skin from the elements - cold, wind, pollution, UVA rays and so forth. It forms an invisible barrier on skin that prevents these culprits from penetrating the epidermis. It stimulates skin's natural defences, so that aggressive external factors are kept well at bay.
