UCLA Researchers Develop Mineral Sunscreen Formulation to Reduce White Residue from Zinc Oxide

Researchers at UCLA have developed a new mineral sunscreen formulation that reduces the white, chalky residue commonly associated with zinc oxide-based sunscreens. This advancement addresses a long-standing cosmetic issue in mineral sun protection products, offering a potential improvement in user experience without altering the chemical composition of the active ingredients.

The innovation focuses on manipulating physical particle properties rather than introducing new chemicals. Zinc oxide, widely used in mineral sunscreens for its ability to block harmful UV rays, often leaves a visible white cast on the skin due to its particle size and distribution. The UCLA team has refined these physical characteristics to minimize this effect while maintaining the sunscreen’s protective qualities. This development could mark progress in making mineral sunscreens more appealing and accessible to users seeking effective sun protection without compromising aesthetics.
