Abstract

Reciprocity for sunscreen solar protection factors (SPFs) and for delayed erythema was examined using a solar simulator equipped with neutral density filters to vary the beam intensity. Similar SPFs were obtained over a 15-fold intensity difference, using a sunscreen with a low (SPF-4) and a high (SPF-15) protection factor. Reciprocity was also observed for delayed erythema in unprotected skin.

摘要

使用配备中性密度滤光片以改变光束强度的太阳模拟器，对防晒霜的防晒系数（SPF）和延迟红斑的互易性进行了研究。使用低防护系数（SPF - 4）和高防护系数（SPF - 15）的防晒霜，在15倍的强度差异范围内获得了相似的SPF。在未受保护的皮肤中，对于延迟红斑也观察到了互易性。
