How to Apply Cologne and Perfume
Perfume and cologne should be applied to pulse points (wrists, base of the throat, inside of the elbow or knee). These are places where blood vessels are closest to the skin; therefore, your skin warms the perfume and causes it to gradually release its fragrance over time.
Rubbing your wrists together will also speed the release of the fragrance, but experts say this bruises the fragrance and diminishes its endurance. Putting cologne on the pulse points should negate the need to rub your wrists together anyway.
Perfume and cologne usually contain alcohol which helps the fragrance evaporate so others can smell it. The warming property of your pulse points assist with the evaporation.
