Botox: preventative?

[Anonymous]

I am 35 and just had my second kid, and I feel like this one pushed me over the edge. Body is worse, a few greys now, skin is worse. I am giving myself a forehead wrinkle because I frown in my sleep--I can literally tell when I wake up that it is more prominent. I feel like I am about a 5 on the scale of 1-10 of other women my age in terms of my face for skin quality, wrinkles, etc. I never pegged myself for a botox person (who does, I guess, but just because of my income level, folks in my community dont seem to, etc.) If I ever did botox i would want to be very very cautious and conservative but has anyone ever done it for prevention? Does it work like that? Would love input.
