Glycerin

Glycerin is one of the most familiar humectants in skincare: a simple, skin-compatible molecule that draws water into the outer layers of the skin. It helps the complexion feel soft and comfortable and supports the skin's natural moisture barrier, which is why it appears so often in cleansers and moisturisers designed to leave skin feeling cared for rather than tight.

In the iS Clinical range, glycerin balances the Cleanse step in Cream Cleanser, Warming Honey Cleanser and Cleansing Complex Polish, so skin is left clean without feeling stripped. At the Hydrate step it features in Brightening Complex and SHEALD Recovery Balm. For skin after in-clinic procedures, explore our post-procedure and recovery skincare.
