SUNSTONE POWDER
Description
Sunstone powder is a naturally derived ingredient sourced from the sunstone gemstone, known for its shimmering, iridescent properties. This finely milled powder is composed primarily of feldspar minerals, including oligoclase and orthoclase, with copper inclusions that give it a distinctive golden-orange hue. In skincare formulations, sunstone powder serves both functional and aesthetic purposes.
The powder's physical properties make it an effective exfoliant, gently removing dead skin cells and promoting cell turnover. Its mineral content, rich in silicon and aluminum oxides, may offer mild astringent properties, potentially helping to refine pores and balance oil production. The copper content in sunstone powder is believed to support collagen synthesis and skin elasticity, though more research is needed to confirm these effects.
Cosmetically, sunstone powder imparts a subtle, warm-toned shimmer to products, enhancing the skin's natural glow. It's commonly used in illuminating primers, bronzers, and body lotions. When formulating with sunstone powder, it's essential to consider particle size for safety and efficacy. While generally well-tolerated, patch testing is recommended, especially for those with sensitive skin or mineral allergies.
