I'm only 28, but I already have horizontal lines on my forehead. I take good care of my skin but I have very expressive eyebrows. I hated how foundation would settle into the lines and make them look more prominent, so I decided to try botox on my forehead. I don't have any bunny lines, 11's or crow's feet (yet). I purchased 10 units of botox at $12 per unit. I went to a plastic surgeon's office in my town, and there is a lovely RN who administers all of the injections. I thought I would need 10 units for my forehead, in speaking with my friends who have had their foreheads done and 10 units was what they needed. The injector told me I would need a little less than 10 units and I could bank the rest to use at a later time. I believe she used about 6 units. The injections did not hurt at all but each time the needle poked my skin, there was a crunchy sound lol. I was told not to lay down and to sit up straight for at least 4 hours after. I was told the botox would last 3-4 months. I started noticing results after about a week. The top of my forehead did not move at all, but I was still able to move my eyebrows. I didn't want to look frozen or "done", so the fact that I was still able to move my eyebrows was nice. My forehead was completely smooth and my foundation looked AMAZING on my forehead.
It's only been 9 weeks since my first botox treatment, and I already feel like it has all worn off. My metabolism is pretty high, so that could be the reason. I don't know if I need more units next time, or if botox just doesn't last very long on me. I've only had 1 treatment so far, so time will tell. I definitely want to keep doing it as a preventative to keep the lines from getting too deep. I feel that every woman who is concerned with aging should add botox to their arsenal. It's so common now a days that it no longer is a big deal to tell people I've had botox. Everyone is doing it!
