Aftershave, just as it sounds, is a product used mainly by men after they finish shaving. Aftershaves are used to heal worn-out skin caused by the effect of a sharp blade on the outermost skin lining. They are made specifically to be applied on the face so as to heal the surface. Aftershaves are made with certain substances that help to reduce the power of sensation during the healing process.
The common aftershaves exist in three forms, such as lotion, liquid, and gel. Although they might be made to contain fragrance, they are not meant to serve as perfumes. Cologne, on the other hand, is a type of perfume that has 2% to 5% essential oils in its composition.
The presence of the essential oils is the reason why cologne is being used mostly by men, although it is equally available to be used by women. Unlike aftershaves that have skin moisturizers in their composition, cologne doesn't contain skin moisturizers.
