“Botox Works, What else Matters?”

I've had many botox injections over the past 2 years, and I'm a totally happy customer. It works just as marketed at easing signs of wrinkling around my eyebrows and eyes. The cons I associate with botox is the time it requires for maintenance. Setting up routine appointments (and making them in time!) is a hassle. I'm intrigued by newer products like restyline that last longer than botox--that's my understanding--but haven't found the need to change horses. Why stop something if it's working?
