Revelika safety grade

Overview

A polysaccharide produced by bacterial fermentation of sugars, used to thicken water-based formulas and hold them together. It is what gives serums and gels their body and what keeps suspended particles from settling out in the bottle.

Who it's for

Nearly everyone, though not as a choice — it is a texture ingredient rather than an active, and it turns up in gels, serums, cleansers and creams at every price.

Cautions

It does nothing for skin on its own, so a product cannot be judged better or worse for containing it. Gels built heavily on gums are the ones most likely to pill or roll when layered under sunscreen or makeup, which is a texture complaint rather than a safety one.
