I know we're making a huge claim here but hear us out. Although SPF's above 50 do exist, are they really protecting us up to 50% more? No. Not really. And here's why.
Sunscreens with a higher SPF should offer more protection from the sun’s harmful ultraviolet radiation, but only to a certain extent. It's not that simple. Harmful UV radiation reaches the earth in the form of UVB and UVA rays. UVB radiation plays a key role in skin cancer, aging skin, sun spots and other sun damage. SPF, meaning Sun Protection Factor, refers mainly to the amount of UVB protection a sunscreen offers. In theory higher SPF sunscreen can help--but get this: An SPF 15 sunscreen blocks 93 percent of UVB radiation, while an SPF 50 sunscreen blocks nearly 99 percent.
Anything over SPF 50 will cost you a couple dollars more but is only protecting you a fraction of a percentage more. So yes, technically a SPF 80+ does ~exist~ but it's protective qualities are nearly the same as a SPF 50. For a typical consumer this notion can be very dangerous. Products with very high SPF's (with barely higher protective qualities) encourage individuals to neglect safe sun behaviors, like seeking the shade and wearing sun-protective clothing. Very high SPF's can create a false sense of security, prompting consumers to stay out in the sun longer.
We beg you, be smarter than that! Any licensed Aesthetician will tell you that you must reapply your sunscreen every two hours (and even sooner if you've been sweating or have been playing water sports). Severe sunburn can ultimately lead to blisters, poisoning, permanent damage, wrinkles or even skin cancer. Be smart! Slather up!
