Dual Protection and Cooling Effect
A groundbreaking sunscreen prototype combines UV protection with a cooling effect using radiative cooling, keeping skin significantly cooler than both bare skin and existing sunscreens.
Radiative cooling technology, which reflects or radiates heat away, is harnessed in this sunscreen by adjusting the size of titanium dioxide nanoparticles to achieve both UV protection and cooling.
Promising Commercial Potential
Tested in hot and humid conditions, the sunscreen maintained its cooling effect and UV protection, with no irritation on skin, showcasing its stability and efficacy.
At a cost of $0.92 for 10 grams, the sunscreen is competitively priced with current market options, highlighting its commercial viability, especially amidst rising global temperatures.
