SOLUM FULLONUM

Fuller's Earth

Safety grade: A

Fuller's earth is a naturally occurring clay mineral that has been used for centuries to absorb oils and impurities. It's a fine, soft powder that comes from the earth and is commonly used in skincare products.

This ingredient absorbs excess oil and moisture from the skin and product, helps prevent clumping, adds texture and thickness, and makes formulas appear less transparent while controlling how thick or thin a product feels.
