Diamond Powder is a highly pure, micronized form of synthetic or natural diamond crystals. In cosmetics, it is prized for its extreme hardness, light-reflecting properties, and gentle exfoliating ability. It imparts a luxurious sparkling effect and helps smooth the skin surface. This ingredient is commonly used in premium facial scrubs, masks, highlighters, primers, and illuminating products to provide visible radiance, gentle physical exfoliation, and a sophisticated sensory experience.

Origin

Diamond Powder used in cosmetics is primarily synthetic (produced through high-pressure, high-temperature processes or chemical vapor deposition) to ensure purity, consistency, and safety. Natural diamond powder is also used in some ultra-luxury products but is less common due to cost and ethical considerations. The crystals are carefully micronized into fine particles (typically 1-50 microns) for safe topical use.
