I don't frequent this board much - so its a real coincidence that I see this topic.
Just yesterday I had botox and filler - juvederm.
I love both of them - especially the filler.
Keep in mind the change you see is VERY subtle. There won't be any dramatic changes.
The botox lasts 3-4 months. The filler about 6 months.
All the ads will tell you that they last longer, they don't. Here's the thing - yes, botox or filler might last more than 4 months but its wearing off every day. So you might start out with say 100 units on day 1 and at 3 3/4 months you have maybe 50 units left - so technically thats 4 months. Same with the filler, it gradually disapates so at 6 months you will only have a tiny bit left.
I don't know if I'm making sense the way I'm explaining it.
Some of the filler does stick around for a long while and they claim that you can "build it up" and eventually need less and less. I've been getting filler for a few years now and if any has "built up" it sure hasn't been much.
All that said - its not cheap either. BUT I like it and I like the effect it gives.
