what do you know about sunscreen?
There are two basic types of sunscreens, physical and chemical blockers. Physical blockers like zinc oxide or titanium dioxide reflect the sun's ray by acting as physical barrier. The chemical blockers on the other hand absorb the sun's ray. It deteriorate more quickly than physical blockers because of its ability to absorb the sun's rays diminishes. Generally, it is more transparent when rubbed on the skin.
