"In this study, a group of 199 skiers/snowboarders in Vail, Colorado, were randomized to apply SPF 50 sunscreen to one side of their face and SPF 100 to the other. No instructions were given as to the density of application or the timing of reapplication so that a real-world usage was achieved. Erythema was clinically accessed the following day by a blinded investigator. On average, partiicpants applied sunscreen to a density of approximately half that mandated for SPF testing in the laboratory setting and most did not reapply. When assessed, 55.3% of participants exhibited more sunburn on the SPF 50 side as opposed to only 5% on the SPF 100 side.
These important results remind us that findings obtained in a controlled laboratory environment may inaccurately translate to real life. Those who question the added benefits of high-SPF sunscreens due to minimal added protection from UVB fail to consider that the actual protection in real-life settings is typically substantially lower than those resulting from laboratory tests. The results of this study demonstrate that higher SPF sunscreens provide meaningful added sunburn protection in real-world situations, suggesting that the proposed FDA SPF cap of 50+ would not be beneficial or appropriate."
