" Is the sunscreen safe?"

Well you can set aside your worries. The ingredients of foremost concern are nanoparticles of zinc or titanium dioxide as these can cross over the skin barrier and enter the bloodstream. So just look out for sunscreens without these nanoparticles and you’re good to go. Some people are also concerned about oxybenzone present in these sunscreens that many researches have shown to disrupt hormonal balance. Guess what? The lab rats used in the research were exposed to as much oxybenzone as you will take up only if you apply sunscreen every single day for 30 years. It’s the dose that makes the poison. So harmful? I think not. 3.
