Are You <br />Applying Your <br />Sunscreen Correctly? A new study published <br />in the journal PLOS ONE <br />found that misapplication <br />of sunscreen is common. Specifically, the study found that when <br />people used a moisturizer with SPF <br />rather than a traditional sunscreen, the study participants "covered a smaller <br />area of the face," making them more <br />vulnerable to skin cancer. SPF stands for sun protection factor, <br />and measures how well a sunscreen <br />can block harmful UV rays that cause sunburn. More than 3 million people <br />are diagnosed with <br />skin cancer each year. The best way to <br />prevent it is to apply <br />sunscreen thoroughly. The study authors suggest <br />to make sure to apply it to <br />the eyelid region as well. And while the authors say that <br />applying a moisturizer with SPF<br />is better than nothing, "it should <br />not be considered the equal of sunscreen."
