Synthetic Sapphire

What is Synthetic Sapphire?

Synthetic sapphire consists of lab-grown corundum, a pure crystalline form of aluminum oxide (Al2O3), prized for its hardness and clarity. In cosmetics, it appears as fine micronized powder, primarily functioning as an abrasive to physically slough off dead skin cells and as a bulking agent to enhance product texture and volume. This inert mineral provides a controlled, non-chemical exfoliation suitable for face and body products like scrubs, polishes, and primers. Its durability allows precise particle sizing for mild to moderate abrasion without scratching delicate skin. Regulatory bodies recognize it as safe for topical use in rinse-off and leave-on formulations, where it contributes to even application and a silky feel.
