About this study

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.

Being tested
Inorganic sunscreen, Organic sunscreen

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Inorganic sunscreenOther

    Inorganic sunscreen will be applied evenly to 2 areas on the back of the subject with a 1 cc syringe and gloved finger in an amount of 2 mg / cm2. In the first session, one area will be irradiated 20 minutes after sunscreen application. In the second session, the other area will be irradiated after the subject has swam for 1.5 hours.

  • Organic sunscreenOther

    Organic sunscreen will be applied evenly to 2 areas on the back of the subject with a 1 cc syringe and gloved finger in an amount of 2 mg / cm2. In the first session, one area will be irradiated 20 minutes after sunscreen application. In the second session, the other area will be irradiated after the subject has swam for 1.5 hours.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. SPF change after swimming for 1.5 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.

    Measured: 24 hours

Secondary outcomes (2)
  1. Inorganic sunscreen SPF

    SPF resulted from in vivo method, conducted before swimming. SPF were calculated using MED test. The test itself will be conducted in 2 days. Irradiation will be conducted on the first day and MED result will be collected 24 hours after the irradiation.

    Measured: 24 hours

  2. Organic sunscreen SPF

    SPF resulted from in vivo method, conducted before swimming. SPF were calculated using minimal erythemal dose 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.

    Measured: 24 hours
