Study population: Subjects have been recruited from the panel of the centre. An investigator made a dermatological examination of the subjects before inscription in the panel. Data from this clinical examination, stored in the computer database with the consent of the subjects, can ensure the recruitment; computer software being questioned based on the eligibility criteria of the study.

Brief summary: The aim of this study is to assess the dermatological and ophthalmological tolerance of the investigational product Baume visage / Face balm RV4942A - RY1985 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 (31 subjects on D22) present hypersensitive, reactive and intolerant skin on face. They are stinger subjects, with a dry to very dry skin.

Timm\*: 10 to 30 minutes after first application

Detailed description: his study is a national, monocentric, non-randomized open trial, conducted in adults presenting hypersensitive, reactive and intolerant skin on the face, with a dry to very dry skin.
