Fortunately, the geniuses on Pinterest have a solution to this conundrum: just make your own using what mother nature gave 'ya. There are countless recipes for sunscreen on the site, many of which contain natural ingredients scientifically proven to offer protection from the sun's piercing light, including coconut oil, raspberry essential oil, and zinc and titanium oxides.
Unfortunately, it's utter garbage. When researchers surveyed a wide sample of these recipes on Pinterest, they found that almost 70 percent offered next-to-no protection from the sun -- meaning that they haven't invented sunscreen, so much as fancy, expensive basting juice. This is even though many recipes made specific claims about the level of protection offered by their sunscreen, with the majority saying theirs is rated to SPF 30 -- despite zero testing.
"But, wait, didn't you say these recipes contain ingredients that offer protection against the sun?" Yeah, but in a majority of the recipes, the level of these ingredients in each recipe was so low as to be practically useless. Not to mention, some ingredients -- such as zinc oxide -- are such a challenge to work with, that incorporating them to a reasonable degree is going to be hard for anyone that doesn't have access to expensive manufacturing equipment. So, basically, everyone who attempts these recipes.
