Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental group<br>This study is designed as a single group assignment, because the 4 dressings (3 placebos and 1 containing the product) will be applied in all volunteers. This means that the region in which the tested product will be applied will be compared with the other placebo regions in the same volunteer. | Device: Intimate Lubrificant Gel<br>* All the volunteers will receive the application of four dressings (3 placebos and 1 containing the tested product). After a certain period of time, photoirritation and photosensitization will be measured through the evaluation of tested region.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Photoirritation as measured through the use of dressings containing tested product and placebo | The photoirritation will be measured with the use of four dressings that will be applied in the volunteer (3 dresssings containing different placebos and 1 containing the product). After some hours, the region is evaluated and radiated with UVA. That procedure occurs during the period of five days. | 5 days | 
| Photosensitization as measured through the use of dressings containing tested product and placebo | The photosensitization will be measured with the use of four dressings that will be applied in the volunteer (3 dresssings containing different placebos and 1 containing the product). After some hours, the region is evaluated and radiated with UVA. That procedure occurs during the period of 32 days. | 32 days |
