Since biological evolutionary forces have forever been fighting the sun are our bodies MORE or LESS suited to dealing with UV damage vs oxybenzone damage? Since oxybenzone can intercalate DNA rungs under extremely high local concentrations (forcing some molecules into cavities), or by photo-oxidation converting to radical cation, or in the presence of ethanol which lowers DNA hydration layers and can widen the inter-pair base gaps, then is it causing MORE DNA damage or LESS DNA damage than the Sun's ultraviolet radiation which can contribute to cancer under real world conditions?

Either way it doesn't matter, use mineral sunscreen. Of course if you use bottom tier sunscreen formulated in the 60s you're asking for troubles
