KoboBlur™ 100 Natural is a Soft Focus Complex made only of minerals and natural ingredients, using no plastic particles, with complimentary refractive indexes to scatter light in a wide range of formulas. In vitro tests show it exhibited the same effect regardless of the media into which it was dispersed. Panel testing scored high for its capacity to hide skin imperfections and for its nice skin feel. Micron-sized powders are very popular today for their soft focus effect. Studies have shown that the refractive index of the particles is an important characteristic that affects their efficacy. However, it can be challenging to find a particle that is efficient in multiple formulas because refractive index of the formula varies with its composition and after application on the skin.

KoboBlur™100 Natural是一款仅由矿物质和天然成分制成的柔焦复合物，不使用塑料颗粒，具有免费的折射率，可在多种配方中散射光线。体外试验表明，无论其分散的培养基如何，它都表现出相同的效果。由于隐藏皮肤瑕疵的能力以及其良好的肤感，面板测试的得分很高。微米级粉末因其柔焦效果而非常受欢迎。研究表明，颗粒的折射率是影响其功效的重要特征。然而，找到在多个配方中有效的粒子可能是具有挑战性的，因为配方的折射率随其组成而变化，并且在施用于皮肤之后。
