What is this
Glycerin
Glycerin is a clear, viscous humectant that occurs naturally in skin as part of its own moisturising system. One of the most studied ingredients in cosmetics, it attracts water into the upper layers of the skin, helping formulas hydrate, soften and defend against feelings of dryness with exceptional gentleness.

Questions about glycerin
Is glycerin good for your face?
Yes — glycerin is one of the most effective and most studied humectants in skincare. It draws water into the skin's upper layers and keeps it there, so skin stays hydrated, soft and comfortable. Its long safety record makes it a staple of daily-use formulas.
What does glycerin do in skincare?
Glycerin attracts and binds moisture. In leave-on products it hydrates and smooths; in cleansers it counterbalances washing, so skin is left clean without feeling stripped or tight. It also supports the comfortable, supple feel of a healthy skin barrier.
Does glycerin clog pores?
No — glycerin is oil-free and non-comedogenic. It hydrates without adding heaviness, which makes it as suitable for oily and blemish-prone skin as it is for dry skin.
Can glycerin irritate sensitive skin?
In a finished formula, glycerin is among the best-tolerated ingredients in cosmetics. The cautions found online concern undiluted pure glycerin — which is not how skincare uses it. Properly blended with water, as in every Nine Aurora formula, it is gentle and soothing.
