Summary

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.

Conditions
