Student’s Last Name1Student’s Name Instructor’s NameCourse Number23 September 2019Efficacy and Validity of Latest Research on the Effects of Using SunscreenThe efficacy and validity of any research study should be evaluated from analyzing the evidential pattern of the research work and the journals and publications depicting the research study’s outcome. There have been myriads of research studies on the effectiveness of using sunscreen, but not all of them can be relied on (from the perspective of validity). A recent study result published by the United States Environmental Protection Agency (EPA), which itself is a valid source of information and an authority in terms of commenting on the concerned safety and health related issues, depicts that though sunscreen’s use is effective in protecting the skin from carcinogenic transformations, it is very much essential to determine the degree of the Sun Protection Factor (SPF). The study reveals that user must be aware of the fact that though SPF of at least 15 is recommended; it is unsafe to use SPF of 30, erroneously considering the figure to be indication of double effectiveness (EPA). It has been observed that, “when properly used, an SPF of 15 protects the skin from 93 percent of UVB radiation, and an SPF 30 sunscreen provides 97 percent protection” (EPA). And this indicates that it would be wrong to assume that SPF 30 has a potential to protect the skin double than its counterpart 15. The research finding is evidential in nature, and as it has been published by a credible governmental agency, dedicated to the protection of health of the citizenry; the research finding should be considered both effective and valid.
