IN-USE TOLERANCE STUDY UNDER DERMATOLOGICAL AND OPHTHALMOLOGICAL CONTROLS AND EFFICACY ASSESSMENT (Face Cream)

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to assess the dermatological and ophthalmological tolerance of the investigational product Crème visage / Face cream RV4941A - RY1987 after 21 days of twice daily use on the study areas, under normal conditions of use. The aim of this study is also to: evaluate the cutaneous sensitivity by a stinging test at D1 T0 and D22. evaluate the cutaneous sensitivity by a sensitive scale at D1 T0, D1 Timm*, D8 and D22. evaluate the soothing efficacy by an efficacy questionnaire at D1 Timm*, D8 and D22. evaluate the cosmetic acceptability by a questionnaire at D22. This study is conducted as a national, monocentric, non-randomized open trial. The 33 subjects in this study present hypersensitive, reactive and intolerant skin on face. They are stinger subjects, with a normal to combination skin. Timm*: 10 to 30 minutes after first application
