Actually the more body you cover the more diffusion occurs so its best to hold the bottle a 5 or 6 inches away from your application point and sweep while you spray however we tend to tell new people to just start with there pulse points.
Here are some application tips you can try once you get going
Most of the alcohol sprays last from 3 to 6 hours. We all are biologically different and live in different environments so the body may heat up more or less so its hard to pin point a exact time.
IG is said to last about 4 to 5 hours while some people find Ishine lasts 3 to 4.
Oil based like A314 can last 12 hours or better.
I find the first 3 hours with any mix are the most effective then slowly the hits become more subtle.
