You use a Cologne and perfume after shaving or the aftershave treatment. You do not spray a cologne and perfume directly on the newly shaved skin. A little bit of cologne behind the ears in the neck region or on the wrists is sufficient. You should not turn the applied odor dry between the hands or wrists. One or two puffs, and that's it. A cologne and perfume develops. In the beginning you may still smell the alcohol. After a few minutes you get the scent that will smell the rest of the day. An aftershave, cologne and perfume contain alcohol and odor components. Never use alcoholic shaving products if you have dry or sensitive skin.
