BACKGROUND
The use of sunscreen products has grown considerably in the last few decades because sunscreen products considered as one of the most important ways of skin protection against UV rays by different mechanisms such as reflecting, absorbing, or scattering. Excess expose to UV causes sunburn, early skin aging, and skin cancers.
OBJECTIVE
This review aimed to review and compare prominent in vivo sun protection factor (SPF) determination protocols and investigate their approach in test criteria. Finally, this can help skin care specialists to choose the comprehensive SPF determination protocol.
METHODS
Four current SPF determination protocols including ISO 24444, AS/NZS 2604:2012, CEN 2006, and FDA 2011 were selected and compared to each other.
RESULTS AND CONCLUSIONS
Despite the similarity of the test method among these protocols, there are some obvious differences in test criteria which results in a better performance in the individual steps of the test process for each of these methods.
背景
在过去几十年中，防晒产品的使用量大幅增长，因为防晒产品被视为通过反射、吸收或散射等不同机制保护皮肤免受紫外线伤害的最重要方式之一。过度暴露于紫外线会导致晒伤、皮肤过早老化和皮肤癌。
目的
本综述旨在回顾和比较主要的体内防晒系数（SPF）测定方案，并研究其在测试标准方面的方法。最后，这有助于皮肤护理专家选择全面的SPF测定方案。
方法
选择了四种当前的SPF测定方案，包括ISO 24444、AS/NZS 2604:2012、CEN 2006和FDA 2011，并相互比较。
结果与结论
尽管这些方案之间的测试方法相似，但在测试标准上存在一些明显差异，这导致这些方法在测试过程的各个步骤中表现更好。
