That's the amount you need to be applying to your body yes, your entire body.

And don't forget your face. That pretty mug of yours only requires about a nickel amount.

If you use less, it doesn't necessarily mean you'll burn, but it does mean you're not getting all the benefits labeled on that SPF bottle of
yours.


You skimp on reapplying.

Doing it once is not enough.

You need to reapply the same amount as above after you take a dip, excessively sweat, or if it's been more than two hours since
you've applied.

Also keep in mind that: "Water resistant" is not the same thing at "waterproof."

You still have to reapply after you hit the water.


You buy the wrong SPF.

SPF is the amount of UVB rays you're protected against, aka the rays that cause your skin to burn.

It is not the amount of UVA rays you're protected against, aka the rays that are responsible for aging.

Meaning you still need to try to stay out of direct sunlight as much as you can.

Also, no, the SPF number does not correlate to how much your sunscreen is protecting you.

A sunscreen with SPF 100 doesn't block out 100 percent of the rays only about 98 percent, while a lotion with SPF 30 will protect you
against roughly 95 percent of rays


You don't rub in sprays.

Sprays are much easier to apply and less odorous.

The downside, however, is that you're more likely to forget places and have uneven coverage.

To make sure you're getting the coverage you need, spray continuously on a specific part for about five seconds and then rub it in and out.

Holding the nozzle down for that period of time allows for more even distribution while rubbing ensures you don't miss a uncovered surface.


You don't apply it when you know you're going to be inside.

Windows! WINDOWS. Those glass panes allow rays to reach your skin, so it's still important to protect yourself even if you aren't spending hours outside.

And don't forget car time. Drivers should keep SPF handy, as UV rays penetrate the glass and often affect only one side of your body, meaning while you'll only have half the risks, you'll have all the embarrassment of a one sided farmer's tan.

And office settings aren't particularly safe either skin discoloration can occur just from light emitted from computers, workplace lighting, and cell phone light.
