I got my first botox injection when I was 22. I know this is a really young age to be worrying about wrinkles but I had one really deep line across my forehead that would become pronounced whenever I did anything, especially concentrate. It used to drive me nuts! I noticed it most after I would straighten my hair (I guess it involved alot of concentration).So I decided to give botox a go.
I think I get around 4 units injected into my fore-head, every 3 months or so. It has done wonders for the lines on my forehead, it also give my eyebrows a really nice peak/shape. I love it!
I can always tell when it is starting to wear off because my eyebrows start to go flat and dont look as nice. I still have movement in my forehead and look really natural, I can raise my eyebrows etc.
My friends think I'm crazy, but I think prevention is the best cure. If you're curious give it a try, if you dont like the results they will wear off after a couple of months. I have bought a million expensive wrinkle creams but nothing has worked this well.
