Diatomaceous Earth: A naturally occurring, fine powder made from the fossilized remains of diatoms (microscopic algae). In skincare, diatomaceous earth is used as a gentle exfoliant due to its abrasive texture. It works by sloughing off dead skin cells, revealing a smoother, more polished complexion. 

Dimethicone: A type of silicone that provides a smooth, silky feel and helps to lock in moisture. It forms a protective barrier on the skin's surface, preventing water loss and improving skin texture.

Dipotassium Glycyrrhizate: A derivative of licorice root known for its soothing and brightening properties. It helps to reduce redness, irritation, and hyperpigmentation.
