I had botox and radiesse done before my wedding to smooth out a few wrinkles and fill in my laugh lines. I was really nervous that I would look stiff or unnatural. The results were flawless and noone guessed I had any work done. I looked like a glowing, well rested version of myself. It didn't hurt at all.
The only cons is the price. It is expensive but you get what you pay for. Don't skimp on the Doc!
