Even though you’ve likely usedsunscreenand sunblock interchangeably, they’re actually different products with different usages.
It turns out, the main difference between sunscreen and sunblock lies in their names.
While both lotions protect your skin from the sun, the way that they inhibit UV rays differs.

As such, their chemical makeup does as well.
According toHealth, sunblock doesn’t require a ton of rubbing in because it won’t go away completely.
Because these lotions can only somewhat rub in, many people opt for the classic sunscreen.

Health reports that people with sensitive skin are better suited to using sunblock because sunscreen often contains more chemicals.
But, if you prefer sunscreen and it keeps you from getting red, load up the 35 SPF.
