We're constantly being told how important it is to wear sunscreen, but rarely are we told how to wear it. If you've ever wondered if you're using sunscreen the right way, you aren't alone. Maybe you've wound up with a nasty sunburn even though you took time to apply SPF. Read on for everything you need to know about proper sunscreen application.

The Difference Between Sunblock and Sunscreen

Although sunblock and sunscreen do the same things, they work a bit differently. Sunblock blocks UV rays and starts working the moment you put it on. Sunscreen, however, works by absorbing into the skin. It needs to be applied 20 to 30 minutes before sun exposure to give it ample time to sink in.

The one thing that doesn't vary between sunblock and sunscreen is SPF. A sunblock and a sunscreen that are both SPF 30 provide the same level of protection. Between the two, there is no "better" product. The best sunscreen or sunblock is the one you enjoy and know how to use.

How to Apply Sunscreen

Sunblock, as previously mentioned, works immediately, but sunscreen needs at least 20 to 30 minutes to absorb into the skin before sun exposure. Both products are applied the same way. The only difference is timing.

Shake the bottle well before you squeeze any sunscreen out. This mixes up all the particles and distributes them evenly in the container. An adult should use about 35 milliliters or 1 ounce of sunscreen to cover their entire body, which is the same amount that would fit into a shot glass. It's also about the same as an adult handful. Remember: most people don't apply enough sunscreen, so it's okay to use more than you think you should. Cover all of your skin that will be exposed to the sun. This includes often neglected areas like your back, ears, behind your knees and your legs. Continue to reapply throughout the day. If you've been in the sun for 30 minutes, you might want to reapply more sunscreen to get any places you might have missed. Definitely reapply 1 ounce of sunscreen at least 2 hours, even if you haven't been sweating or swimming. Always reapply 1 ounce of sunscreen after swimming, sweating or toweling off.
