What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Side-by-side Comparison (overall difference) of Sunburn. | The side-by-side comparison utilized the following condensed two side overall difference scale: L1 = subject's left side noticeably more sunburned than right side, 0= no difference in sunburn, R1= subject's right side noticeably more sunburned than left side. The 0 outcomes were excluded from the analysis. | Day 2 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Difference in Erythema Score Between Left and Right Sides at Day 2 | Erythema was assessed using a scale of 0 = no burn, 1 = possible burn, not clearly defined; 2 = defined redness clearly caused by UV; 3 = severe sunburn with pronounced redness; and 4 = edema and blisters | Day 2 |
