Experimental group

Description:

Participants will receive two of six sunscreens (A, B, C, D, E, and F) at Visit 1 (Day 1) to apply to whole lower legs (1 sunscreen per lower leg), between the knee and ankle. Participant will then select one of the two sunscreens randomly assigned to lower legs and apply the selected sunscreen to full face. After lower legs and facial applications are completed, a trained designee will delineate six 4 centimeters (cm)\*4 cm test sites on the participants' volar forearms (3 test sites per volar forearm). The six sunscreens will be randomly assigned to the six test sites at a dose of 2.00 +- 0.05 milligrams per centimeter square (mg/cm\^2) using a 1cc tuberculin syringe (without a needle) and a clean finger cot for approximately 20 to 50 seconds and applied by a trained designee.
