Botox is almost too good to be true! My fear is they will find out that is does whatever medical tragedy its sure havoc upon us...in about 20 years! Alzheimers anyone?! Perhaps the old-fashioned knife option isn't so bad afterall... Nadine, do you have any information on brow lifts-- the endoscopic, virtually painless, very minor, ever-so-subtle, lifting kind for the squeamish? It SO figures! Botox is almost too good to be true!

Neuroscience study in more detail. Kudos for trying to read through all the science. I'm in grad school for neuroscience and a lot of those articles are hard for me to process, so I can only imagine how many times you had to read over this stuff! I love the "susan" and "Larry" names. However (sorry the nerdy scientist in me has to point it out) just one small correction to your interpretation - Susan (Ach) sends nerve signals to the muscles, not to the brain. Muscles then interpret the Susan and result in contractions that cause movements. The issue in this study is that it's possible for some signals to move backwards along the neurons, to go back to the brain. So the concern comes from whether or not the Botox, which is injected into the muscles, could potentially move backwards and get to the brain. Otherwise, good job with your analysis. Whenever there is media hype about medical issues, I like to go back to the original study - usually, the media totally misconstrues things. Hope you don't mind my nerdy correction - I love reading all your beauty tips, as I'm definitely not an expert in that area, so just thought I'd share some of my science knowledge :) Hi Jolie, thanks for addressing the J.
