Sunblock physically blocks UV rays with active ingredients like zinc oxide or titanium dioxide, providing a barrier on your skin. Sunscreen, on the other hand, absorbs UV rays using chemical ingredients like oxybenzone and avobenzone to prevent skin damage. Sunblock tends to be thicker and more opaque, while sunscreen is usually lighter and more transparent.
