Men should spray cologne on their pulse points where the skin is warmer, such as the neck, wrists, behind ears, inner elbows, chest, and sometimes behind the knees. The warmth at these points helps the cologne mix with body chemistry and project the scent better. It is best to apply cologne to clean, dry skin right after a shower when pores are open, holding the spray 3 to 6 inches away from the skin. One or two spritzes on these pulse points are generally enough without overdoing it. Avoid spraying directly on clothes to prevent scent flatness and potential fabric damage. Some also apply lightly to hair or clothes (avoiding roots) for longer-lasting scent.
