What is Volcanic Ash?

Volcanic ash consists of finely milled particles from volcanic rock, primarily composed of silica, aluminum oxides, iron, and various trace minerals formed during eruptions. In cosmetics, it appears in facial masks, scrubs, cleansers, and peels. It functions through mechanical action as an abrasive to polish the skin's surface and as an absorbent to draw out excess sebum and impurities, promoting a matte finish. Its porous structure helps in mattifying formulations, while mineral content contributes to a velvety texture in powders and emulsions. Commonly sourced from regions like Italy or Hawaii, it provides a natural alternative to synthetic exfoliants, aiding in product texture enhancement without harsh chemicals.
