What makes sunscreen waterproof

Deciding which is more important can be a challenge when both seem to be highly important. For example, when choosing a sunscreen, should you look for something water resistant that will protect your skin from damaging ultraviolet radiation?

Or should you choose a product that is free from harmful chemicals and is not tested on animals? Fortunately, in this case, it is possible to have both.

Unfortunately, if someone's planning to spend more than about two hours outdoors, that one application isn't going to cut it. Sunscreen starts to wear off after a while, and any swimming, sweating or toweling only exacerbates the issue. Likely motivated by memories of particularly painful sunburns, people started cooking up commercial methods to block the sun's penetrating rays.

Originally, this effort focused solely on the UVB part of the spectrum, but now sunscreens frequently protect against UVA wavelengths as well.

There are also UVC rays, but thankfully those aren't an issue -- they get scattered in the atmosphere. Seeking ways to further improve secret formulas, chemists started finding new ingredients to increase their products' effectiveness. Initially, sunscreens simply threw up a physical barrier that reflected or scattered incoming sunshine. Nowadays, however, some offer chemical protection instead, meaning they actually absorb sunlight before it infiltrates the skin. In addition to getting a broad-spectrum sunscreen that's rated SPF 15 or greater, experts say it's a good idea to choose one that's labeled water-resistant or sweat-resistant too.

Be wary of products claiming to be completely water-proof or sweat-proof, though -- if you see that on the side of a bottle of sunscreen, you can safely assume it's not true. No sunscreen is percent impervious to the power of a good sluicing. That being said, some sunscreens are definitely better at withstanding exposure to water or sweat than others. On the next page, we'll take a closer look at how they manage it, and how well they hold up.

The intensity of the UV rays a person will encounter -- and the subsequent crimson consequences -- depends on lots of factors like season, latitude, altitude, time of day, cloud cover and skin type. Plus, while trudging behind a lawnmower can give you a rosy pink glow, a day at the beach can leave you more on par with the unfortunate lobsters served up in oceanside surf and turf joints.

That's because sand and water along with concrete, snow and other surfaces reflect sunlight back up, meaning it hits you coming and going. To make matters worse, even if you started out with a good coating of sunscreen, if your time at the beach lasted longer than two hours and not a second was spent reapplying sunscreen, the chances of a bad burn typically shoot right through the roof. If your fun included activities like frolicking among the ocean waves or sprinting back and forth across a sandy volleyball court, things get even worse.

Those sunburned scientists didn't give up, however, and continued to develop innovative new formulas for more advanced sunscreen products.
