Diatomaceous earth, referred to simply as DE, is a natural sedimentary rock composed of fossilized remains of microscopic algae called diatoms. It has a powdery texture and is rich in silica. DE is commonly used as an insecticide, filter agent, and abrasive substance. It can absorb moisture and is often found in household products and gardening applications.

DE is inexpensive and available commercially in two versions: 1) for pool filters, and 2) labeled as “food grade” for human health and pest control. This post applies to food-grade DE. To make use of what follows, make sure your DE purchase is clearly labeled as food grade.

Where to Get DE

While you should be able to find food-grade DE at home centers such as Home Depot and Lowe’s, you may have trouble finding it in-store. I don’t know why these stores don’t stock it, but instead, offer to deliver it to the store near you or charge extra for home delivery. I continue to find the best deals on Amazon Prime.

Facial Scrub and Mask

DE, with its fine powder texture, can be used as a gentle facial scrub and mask. It contains minerals such as silica, calcium, and zinc, which can be absorbed by the skin.
