The sheer range of perfume oils is enormous. This makes them fairly inexpensive as well, making them offer more bang for your buck. When using a perfume oil, you can apply the oil directly to the warm areas of your body – the perfume pulse points – such as your wrist, the inside of your elbow, behind your ears and the back of your neck. You can apply as much or as little as you wish. Of course, because they are concentrated, they will still smell stronger and richer, and yet they're less likely to leave behind trail like an alcohol-based perfume spray. All in all, perfume oils radiate outward from your skin, making you radiate from inside out.
