I have friends that have had luck with fillers, and they look pretty good. Then again, I've seen a lot of really really bad filler applications. I haven't tried myself, just make sure you look at their portfolio before you decide. See if you like what you see. Its not the filler, its the hands that do the work that matters. Fillers can go very wrong very fast, and it can take a few years to break down. It is definately going to require maintenance, where as surgical intervention is a bit more permanent. Perhaps start with some of the cheaper fillers that break down faster. I say cheaper, but they're all fairly spendy... Some that will break down in 4 to 8 months, so if you're not happy, you only have to deal with it for a year.
