By the end of the study, which was funded by the Australian government, 77% of those told to use sunscreen daily were using it at least three to four days a week, compared with 33% of the control group. (The sunscreen was provided by a sunscreen manufacturer.)

这项研究由澳大利亚政府资助。到试验结束时，被要求每天擦防晒霜的受试者中有77%的人一周至少使用三到四天，而控制组则只有33%的人使用（试验中使用的防晒霜是由一家防晒霜生产商提供的）。

Researchers took silicone impressions of the backs of participants' hands at the beginning of the study and after 4½ years. Trained assessors then graded the patterns of lines and skin coarseness on the hand impressions on a scale of one to six. The damage seen on the surface of the skin reflects the tissue damage underneath the skin, said Adèle Green, senior scientist and head of cancer and population studies at Queensland Institute of Medical Research in Australia and lead author of the study.

研究人员在研究刚开始时以及四年半后对受试者的手背取了硅胶印模。接下来，经过专门训练的评估人员按照从一到六的等级对手部印模的纹路和皮肤粗糙程度进行评分。澳大利亚昆士兰医学研究院(Queensland Institute of Medical Research)高级科学家、癌症和人口学研究负责人、该研究论文第一作者阿黛尔•格林(Ad口le Green)称，皮肤表面的受损情况能够反映出皮下组织的损伤。
