How should the shaving gel be used correctly: is it applied to dry or wet skin? — MR. GROOMER FACE WASH AND SHAVING GEL 3 in 1 150 ML

According to the card, the directions are: wet your face with water, apply a little gel and spread it with a brush until a rich lather forms. The card says nothing about applying it to dry skin, rinsing after shaving or how long to leave it on. In case of contact with the eyes, the card says to rinse them thoroughly with water.

General information (not a manufacturer's instruction): gel residue after shaving is usually rinsed off with water; if the skin becomes irritated, it is better to stop using it.
