Pumice

Pumice is a lightweight volcanic rock formed when lava with high water and gas content cools rapidly. It is highly porous, with a rough, abrasive surface texture. In skincare, it functions as a mechanical exfoliant—a physical agent designed to remove dead skin cells and thickened keratin from the skin's surface.When incorporated into skincare formulations, pumice acts as an abrasive particle that manually buffs away the outer layer of dead skin. It can be found in products designed for targeted exfoliation, though it represents a small fraction of the skincare market.

Pumice works through mechanical abrasion. When rubbed against skin, its rough, porous surface physically dislodges dead skin cells and excess keratin. This action is most effective when the skin is hydrated and softened, as the stratum corneum (outer layer) becomes easier to remove.The abrasive action differs from chemical exfoliants such as AHAs or BHAs, which dissolve bonds between cells. Pumice relies entirely on physical friction to achieve exfoliation.

To minimise irritation, always wet the skin before using pumice-containing products. Use gentle, circular motions rather than aggressive scrubbing. Frequency should be tailored to individual tolerance—typically once or twice weekly is appropriate. Avoid use on active breakouts, inflamed areas, or very sensitive skin. Follow exfoliation with a hydrating and soothing moisturiser.

Pumice is generally well-tolerated when used appropriately on damp skin. Avoid overuse, as excessive mechanical exfoliation can compromise the skin barrier and cause irritation, particularly in those with sensitive, inflamed, or compromised skin.
