PUMICE

Safety grade: A

Pumice is a lightweight, porous volcanic rock with a rough, grainy texture. It's the same material used in pumice stones for smoothing calluses on feet.

Pumice works as a gentle abrasive to remove dead skin and smooth rough areas, while also helping to thicken products and control their texture.

Graded using: COSING.
