What the gurus are saying
Gurus mostly agree Botox is at its best as prevention: it stops the muscle pull that carves lines, so it works best before deep creases set in. Several also praise it for sweating, oily scalp, clenched jaws, and a Botox brow lift. The caveats: loose skin won't tighten, and a poor injection can leave a Spock brow, so pick your injector carefully.
