However, this belief is a fallacy and consumers are best served with sunscreens in which the spectral protection profile is uniform at all wavelengths throughout the <jats:styled-content style=\"fixed-case\">UV<\/jats:styled-content> spectrum.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ics.12353","type":"journal-article","created":{"date-parts":[[2016,7,8]],"date-time":"2016-07-08T07:12:24Z","timestamp":1467961944000},"page":"90-92","source":"Crossref","is-referenced-by-count":7,"title":["Optimizing the spectral absorption profile of sunscreens"],"prefix":"10.1111","volume":"39","author":[{"given":"B.
