LOESS

Safety grade: A

Loess is a fine, silty sediment naturally formed by wind erosion over thousands of years. It's a mineral-rich powder that comes from the earth and is commonly used in skincare products.

Loess absorbs excess oils and moisture from the skin while adding bulk and texture to cosmetic formulations, making it useful in powders and absorbent products.
