The card does not describe the cream as a product for sensitive skin and does not describe an allergy test. It says: do not use in case of hypersensitivity to the components, and if an allergic reaction occurs, stop using it and see a doctor. The full composition (INCI) is on the packaging.
General information (not a manufacturer's instruction): the product name mentions birch leaves; in case of an allergy to plant components, it is better not to use the cream.
