简要总结
Prolonged sunlight exposure in swimming athletes can cause various changes in the skin; among them is sunburn. The use of sunscreen can reduce sunburn effectively. However, various types of physical activity that can trigger sweating, friction, washing with water, or sun exposure after sunscreen use can interfere with its effectiveness in the form of a decreased SPF level. The purpose of this study is to determine and compare the persistence of organic and inorganic sun protection factor 30 (SPF 30) sunscreens after 1.5 hours of swimming.

结局指标
主要结局
SPF change after swimming for 1.5 hours
时间窗: 24 hours
SPF of inorganic and organic sunscreen were calculated before and after swimming. The difference between SPF before and after swimming will be calculated and compared between the organic and inorganic group. SPF were calculated using minimal erythemal dose (MED) test. The test itself will be conducted in 2 days. Irradiation will be conducted on the first day and minimal erythemal dose result will be collected 24 hours after the irradiation.
次要结局
- Inorganic sunscreen SPF(24 hours)
- Organic sunscreen SPF(24 hours)
