Our standard

Two ingredients. That's it.

A pure mineral clay and water. No fragrance, no filler, no preservatives — it's stable because it's dry until you mix it. The way clay was meant to work.

California, USA

Rooted in the source

We own the mines.

For more than four decades we've quietly served as the foundation behind many of today's leading clay-mineral skincare brands. We own and steward our mines, extract and refine each mineral ourselves — every step in our hands.

Now those same exceptional, pristine minerals come to you under our name.

  • Green Desert · Mojave, CA

    Calcium Bentonite. Sourced from the renowned clay dunes of California's Mojave Desert.

  • Kern River Valley · CA

    Kaolin. Harvested from the white-crested peaks of the Kern River Valley.

The ritual

Tear. Mix. Apply. Rinse.

Four steps, ten minutes, and skin you'll keep coming back to. The simplest part of your week, designed to feel like the most important.
