Perfumes and pulse point oils - like roll on essential oils - don't necessarily need to be added to these areas to work. The reason why many people opt for these locations is because of the strength they can add to the scent of your perfume. Pulse points radiate heat, and this heat allows the oils in your perfume to warm up faster and absorb much quicker into the skin. Once absorbed, the aromas of your perfume can last much longer and smell much more potent than they otherwise would have if applied elsewhere. The most common pulse points to use are the wrists, neck, and jawline area, though other areas can be just as effective.
