What's the difference between After shave, and Cologne? Both After shaves and Cologne are fragrances for Men. After shaves will usually sting as well as close the skin pores, which is helpful after shaving. After shaves are also meant to cool and soothe the skin after shaving to prevent shave burns. Cologne is simply a fragrance, not meant for anything specifically. Cologne is the male equivalent of perfume, for women.
