At 28 you probably don't need it. If you want to try it I would do the area between your eyebrows.
The injections don't hurt much. They are like little pinches or stings. On average you get poked by the needle about 5 times. It doesn't hurt afterward at all and there really isn't any recovery time. The injection sites go down fairly quickly but you will get instructions from the injector about what to avoid right after the injections.
The lasting effects differ. I think it is supposed to last about 4-6 months but I could be wrong on that. In any event if you are 28 that part shouldn't matter. It takes a few days for the muscles to "freeze" fully so you won't see an immediate effect. Once it kicks in it lasts for several months. Then it gradually fades.
