Can Mineral Sunscreen Finally Lose Its White Cast? UCLA Researchers Say Yes For many people, especially those with darker skin tones, mineral sunscreen comes with a familiar frustration: a chalky white or gray residue that lingers long after application. Now, researchers at the University of California, Los Angeles (UCLA) have developed a new zinc oxide design that may significantly reduce this white cast while maintaining SPF 30 protection. Rather than introducing a new sunscreen ingredient, the team changed the shape of zinc oxide particles. By engineering them into microscopic four-armed structures called tetrapods, researchers found they remained more evenly distributed on the skin, reducing the visible white residue commonly associated with traditional mineral sunscreens. The findings, published in ACS Materials Letters, suggest that this approach could ma
