    "body_text": "UCLA researchers replaced conventional zinc-oxide particles with tetrapod-shaped structures that interlock into porous networks rather than clumping. At the same zinc-oxide concentration, the experimental formula reached roughly SPF 30 while appearing less white in laboratory measurements and controlled skin applications, without pigments or surface coatings. Particle geometry may improve both coverage and appearance, but the formulation is a research prototype and has not been established as a commercial or regulator-approved sunscreen.",
