Glycerin

What it is

Glycerin is a humectant that occurs naturally in the skin and is one of the most common moisturising ingredients in skincare. It is derived from plant oils or produced synthetically.

Function

Glycerin functions as a humectant, drawing water into the outer layer of skin and holding it there. It is often paired with emollients and occlusives, which help seal in the water it attracts.

Properties

Glycerin is one of the best-studied and best-tolerated humectants, non-comedogenic and rarely irritating even on sensitive skin.

In tattoo aftercare

Glycerin is a common ingredient in aftercare creams, keeping healing skin hydrated without heaviness. It frequently sits high on the ingredient list of well-formulated products.

Considerations

Very well tolerated. As a humectant it works best in a formula that also contains something to seal moisture in.
