Do people who get fillers see immediate results?

Lately, I feel like I need to correct my nasolabial folds and facial contours, so I was thinking about getting fillers...

I heard that Botox is relatively simple to administer, but filler procedures are actually quite difficult!

So, I'm wondering when I can see the effects after getting fillers!

I've heard that many people get filler treatments because they effectively improve wrinkles and provide a definite youthful look.

Will there be any major side effects if I get fillers frequently?

Once I start getting fillers, do I have to keep getting them consistently for a few years or more?

But my acquaintances told me that filler procedures can be surprisingly risky, so I'm a bit hesitant.

Also, do the costs for filler procedures vary significantly from clinic to clinic?

It would be a good idea to look around at several places and get a consultation for filler procedures, right?
