are debating whether to wear sunscreen, sun protection factors (SPF) moisturizer, or a deadpool mask to protect your face at the beach, take a look at a study just published in PLOS ONE .  The study studied how well volunteers applied sunscreen versus SPF moisturizer on their faces. A team from the University of Liverpool (Elizabeth AJ Lourenco, Liam Shaw, Harry Pratt, Georgia L. Duffy, Gabriela Czanner, Yalin Zheng, Kevin J Hamill, Austin G. McCormick) recruited 84 volunteers (22 males, 62 females) who ranged in age from 18 to 57 years old. ultraviolet ( UV) sensitive DSLR camera. Then the volunteer applied either & nbsp; 0] SPF30 sunscreen or SPF30 moisturizer to his or her face. Next, the volunteer exposed to ultraviolet (UV) radiation. Finally, a second photograph was taken to help determine how much the volunteer had applied the sunscreen or the moisturizer. If volunteer had used moisturizer on the first visit, then the volunteer would use sunscreen on the second visit, and vice versa. The study did not have any of the volunteers wear deadpool masks.
The research team paid the volunteers for their time and offered them copies of the images. It is not clear how many people end up using their study photographs as their dating profile pictures.
The results were bad and badder. On average, volunteers missed 11.1% of their faces with sunscreen and 16.6% of their faces with SPF moisturizer. That is a good proportion of the face that is missing protection from the sun, leaving it at risk for sun damage and skin cancer. On average, it was better to cover their faces than the females, missing 16.7% versus 22.4% of their faces.
Many participants were missing their eyelids. Not in a creepy missing-body-parts and eyes-always-open type of way. Missing eyelids means that they were particularly concerned with covering their eyelids, with an average of 14.0% of eyelid area missed with sunscreen and 20.9% with moisturizer.
The researchers also asked participants whether they agreed with the following statement, "I applied (sunscreen or moisturizer) to all areas of my face, ”before and after seeing the photos of themselves. Before seeing the photos, most were confident that they were all of their faces with 77 of 84 saying that they agree or strongly agree with statement after applying sunscreen and 73 or 84 after applying moisturizer. But after they were faced with the photographic proof, many did and about face with 46 or 84 at the end of the sunscreen saying that they "disagree" or "strong disagree" and 45 of 84 doing so at the end of the moisturizer day. In other words, people were overconfident about their ability to cover their faces.
It's not too surprising that people didn't cover their eyelids well. First of all, you can't see most of your eyelids. Blinking really fast will not allow you to do this. If you can indeed see most of your eyelids, see if you have gone horribly wrong.
Secondly, rubbing over your eyeball is not always the most comfortable thing to do. Eyeball rub to fall well below back rub and foot rub on the list of preferred spa treatments or romantic evening ideas. Thirdly, you may be worried about getting sunscreen or moisturizer in your eye
Why was coverage with moisturizer significantly worse than with sunscreen? The researchers thought that people tend to use a smaller amount of moisturizer than sunscreen, making it more difficult to catch all of the face. Moisturizer is also a bit harder to spread, compared to sunscreen. All of this suggests that a SPF whipped cream could work better than sunscreen or moisturizer. However, Sunscreen and SPF moisturizer are like underwear. Simply wearing them is not enough. Where you wear & nbsp; them and what and how much they cover & nbsp; also matter. It may be easy to have a good look at either without having an easy way to check what is and is not covered. Do not carry around a UV sensitive DSLR camera selfies
There are alternatives to sunscreen and SPF moisturizer to protect your face from the sun. The aforementioned Deadpool mask is one possibility. A Batman mask would mean that you would have to apply to the lower part of your face. Plus you would have to talk in that & nbsp; ominous Batman voice, which can be buzzkill on the beach. A welder's mask would work too but would have some social cost. The same would apply to a paper bag. The other possibility is a wide margin that can be shadowed over your face.
If you wear sunscreen or SPF moisturizer & nbsp; and make sure that you protect your eyelids, a pair of sunglasses with UV protection could help. Any hat that has a shadow over your eyes like a baseball cap could be effective as well. The same could have been said about a blindfold but, in general, as I have written before for Forbes any & nbsp; activity resembling the Bird-box Challenge is not advisable.
