PERRON360:you can find it at most tattoo/ piercing shops, just ask for lobe oil
I'll be honest, I'd be wary of asking for "lobe oil" without knowing what's in it...that's not a "standard term" in the piercing business and could be anything, since people put all kinds of stuff on their lobes (good and bad). Around here (Ohio) I haven't run across any piercing shop (good or questionable) that carries emu oil, but perhaps this is different where you're from. I would say your best bet is to buy it from BAF, since you can even get a tiny little bottle to try it out before committing to a larger size.
Also, I'd agree that waiting longer than 2-3 months to stretch would be needed to help rebuild some of the tissue. I'd wait as long as humanly possible to give your lobes the best chance and keep massaging with some kind of oil (emu, naked, vitamin E, etc). In fact, if the lobe is that thin, you may want to reconsider how big you want to go and maybe permanently downsize.
