Botox really can help you look younger - it's not magic though, it'll never take you back to your 20s, and if you go overboard or it's poorly done you'll wind up with the classic botox lizard skin look (which generally means don't cheap out & vet your clinic). For touchup work though, and combined with a good (and sane) skincare regime, it can get some very impressive results.
(Personally I don't do it, but family members that do have found it really helps with their dysphoria about aging so... there's that!)
