The card does not name the frequency of use and does not say whether the face can be washed with this soap every day. It describes a soap with tar for the face and body, intended for the care of problem skin: it helps to cleanse the skin, and olive oil promotes softening and moisturising; method of use: lather on wet skin and rinse off with water. Warnings: for external use only; do not use in case of hypersensitivity to the ingredients.
General information (not a manufacturer's instruction): what exactly is meant by “problem skin”, the card does not specify.
