Brief summary
The aim of the study is to determine: * the thickness of the RV4369A truly applied on different areas of the face after single application of the product determined by a multispectral imaging method. * the influence of a second application of the product 15 to 30 minutes after the first application on the product thickness determined by multispectral imaging method. * the influence of the recommendations of use provided to the subjects before application of the product on the product thickness determined by multispectral imaging method .
Detailed description
This study is a monocentric, comparative, open study performed on the face and forearms of healthy adults. Planning of the visits: Visit 1: Inclusion visit (D1) Visit 2: End of study visit (D10), a window of +/- 2 days is allowed for this evaluation, \* The theoretical study duration for each subject is 10 days. The maximal study duration for each subject is 12 days.
Interventions
OTHERRV4369A cosmetic product
The product is applied 1 or 2 times during the 2 study visits. The product is recovered by the technician after application of the product by the volunteer. Application modalities: Inclusion Assessment: The study product is given to the volunteer who applies it to his face (forehead) according to his usual habits. After a waiting time and Multispectral camera measurements, the study product is again applied by the volunteer to his face according to his usual habits. Final assessment: The study product is applied by the Clinical Research Technician on the subject's forearm on 4 delimited areas at specific quantities. After a waiting period and Multispectral camera measurements on the forearm areas, the study product is given to the volunteer who applies it on his face according to the recommendations of use provided by the Technician.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Amounts of sun spray applied to the face, measured by multispectral imaging after single application by the subject | Visit 1 (Day 1) | The product quantity applied by the subject (mg/cm2) will be extrapolated from a reference curve build using an image analysis technique |
| Amounts of sun spray applied to the face, measured by multispectral imaging after 2 applications by the subject | Visit 1 (Day 1) | The product quantity applied by the subject (mg/cm2) will be extrapolated from a reference curve build using an image analysis technique |
| Amounts of sun spray applied to the face, measured by multispectral imaging after 1 application by the subject and according to the recommendations of use provided by the technician | Visit 2 (Day 10) | The product quantity applied by the subject (mg/cm2) will be extrapolated from a reference curve build using an image analysis technique |
| Comparisons between measurements of sun spray amounts determined by multispectral imaging | Visit 1 (Day1) and visit 2 (Day 10) | Comparaisons between an application without recommendations of use (Visit 1), an application without recommendations followed by a second application (Visit 1) and an application according to the recommendations of use (Visit 2) |
