Abstract
A soft-focus composition comprises particles. The particles comprise a substrate with a metal oxide coating. The metal oxide coating covers from about 50% to about 75% of the surface area of the substrate. The particles have a span of from about 0.1 to about 2.1. From about 50% to about 75% of the particles are platelet shaped and the remainder are at least one different shape. This soft-focus composition can be used in cosmetic and personal care formulations to impart a soft-focus effect on the skin to hide fine lines and blemishes while allowing the natural glow of the skin to shine through.
