The most proven humectant in skincare, a small, powerful water-binding molecule the skin's own barrier recognises.
What it is
Glycerin (glycerol) is the benchmark humectant: a small three-carbon molecule that binds water and is found naturally in the skin. Decades of use and research make it one of the most reliable, best-understood hydrating ingredients in existence.
How it works
Draws and holds water
It attracts moisture into the outer skin and holds it there, immediately improving softness, suppleness and comfort.
Supports barrier function
Beyond hydration, glycerin supports the maturation and organisation of the barrier itself, helping skin hold water better over time.
The evidence
Glycerin is arguably the most-studied and most-proven humectant in cosmetic science, effective and exceptionally well tolerated across all skin types and ages.
Worth knowing
Proof that the most effective ingredient is not always the newest, glycerin remains foundational for good reason.
