Negative Control
Sham Comparator group
Description:
Untreated area will be irradiated using a sun simulator with UV irradiation increment of 1.25 to detect MED of the unprotected skin.
Treatment:
Other: Negative Control
Positive Control
Active Comparator group
Description:
After irradiation of the test area with a sun simulator with an increment of UV radiation of 1.25, positive control will be applied. The dose of positive control will be measured in accordance to the application volume (2 milligram (mg)/centimeter (cm)\^2 (± 0.05 mg/cm\^2) and it will be applied using a micro litre syringe in approximately 15-30 small droplets all over the test area. Positive control will be then quickly spread by gently rubbing with a non-saturated finger cot, first with rotating followed by crosswise movements for a final uniform coating on the skin. Spreading time will be between 20 and 50 seconds (s). After waiting for 15 to 30 minutes (min), the test area will be again irradiated (increment of 1.12 or 1.25) with the sun simulator. The irradiation time will depend on the SPF of positive control, participants' skin prototype, determined MED after irradiation and actual power of sun simulator.

Test Product A
Experimental group
Description:
After irradiation of the test area with a sun simulator with an increment of UV radiation of 1.25, test product will be applied. The dose of test product will be measured in accordance to the application volume (2 mg/cm\^2 (± 0.05 mg/cm\^2) and it will be applied using a micro litre syringe in approximately 15-30 small droplets all over the test area. Test product will be then quickly spread by gently rubbing with a non-saturated finger cot, first with rotating followed by crosswise movements for a final uniform coating on the skin. Spreading time will be between 20 and 50 s. After waiting for 15 to 30 min, the test area will be again irradiated (increment of 1.12 or 1.25) with the sun simulator. The irradiation time will depend on the expected SPF of the test product, participants' skin prototype, determined MED after irradiation and actual power of sun simulator.
