Abstract
UVA protection afforded by 6 different sunscreens with a sun protection factor of 21 or more was compared by means of the persistent pigmentation darkening method. Colorimetric and visual assessment showed significant differences in UV radiation-induced pigmentation at 2 hours. The labeled sun protection factor of the tested sunscreens was not predictive of UVA protection level.
摘要
通过持续色素沉着变黑法比较了6种防晒系数为21或更高的不同防晒霜提供的UVA防护。比色法和视觉评估显示，在2小时时紫外线辐射引起的色素沉着存在显著差异。受试防晒霜的标注防晒系数并不能预测UVA防护水平。
