Performance & Formulation Insights for Gemini CS-18

Advanced Color Travel with Silica Encapsulation

Gemini CS-18 achieves its dramatic copper color travel effect through a sophisticated composition of natural mica and iron oxides treated with silica. The silica layer enhances stability, provides a uniquely smooth feel, and optimizes light refraction to produce a more pronounced, vivid color shift as the viewing angle changes.

Optimized for High Coverage & Smooth Feel

The inclusion of CI 77491 (Iron Oxide Red) delivers high coverage and intense payoff with less product. The controlled 20–80 µm particle size ensures a smooth, non-gritty texture that is comfortable on skin and easy to incorporate across systems—from pressed and loose powders to liquid and gel formats.
