Cologne is a type of fragrance that is used to scent the skin. It is a lighter fragrance blend of 2% – 4% perfume oils in alcohol and water, invented in the 18th century by Italian perfumer Giovanni Maria Farina for the royal courts of Europe. The word "cologne" comes from the German city of Cologne, where Farina was living at the time. Cologne is typically fresh and citrusy in character due to a lower percentage of scented essential oils. Cologne is one of the oldest terms for perfume, used to scent the skin, but through the decades it has adopted different meanings. Cologne is marketed towards both men and women and is considered a unisex fragrance.

Cologne is used to neutralize body odor and keep one fresh. It is sprayed on the skin, usually on the neck, chest, and wrists. Cologne can also be used to make a powerful first impression and boost others opinions of you. It can make you appear more polished, refined, and put-together. Cologne can also have a positive effect on your health by easing stress, anxiety, or depression, improving sleep, and boosting feelings of relaxation, confidence, or energy.
