Revelika safety grade

Overview

A thickener made by chemically modifying plant cellulose so it dissolves in water. It builds a clear, slightly stringy gel and is the backbone of many gel cleansers, masks and water-light serums.

Who it's for

Nearly everyone, though not as a choice — it is a texture ingredient that determines how a product pours and clings rather than anything it does to skin.

Cautions

It does nothing for skin on its own, so a product is not better or worse for containing it. Cellulose gels can pill under sunscreen or makeup if layered heavily, which is a texture complaint rather than a safety concern.
