Fillers at 21

Hi! I was wondering if I should get filler at 21. I already have a little under syringe of lip filler and I love it. (sorry if this is not the right sub lol)

I am already planning on getting another syringe of HA filler in Korea later this year. If I was to get chin filler this year, I would prefer to do it in Korea because of the style and price of Juvederm (don't worry I am not going to a factory clinic). I was wondering if its too early to get chin filler as well. I want to get about a syringe in my chin because I want to fix my side profile a bit. I have pretty large eyes and a prominent nose (that I love, so I dont plan on getting work done on there). Since a lot of my facial weight is centered there, I also want the chin filler to balance out my face. I'm honestly not interested in looking like someone else, because I like the way I look/my ethnic features, so this is mostly for balancing.

I'm worried that I am too young to get chin filler, and that it might shift as I get older. For context, over the past few years my face has shed a lot of fat , so I think that I have kinda already grown into my face. I still plan on getting this done in the future if I am too young.

Has anyone else gotten filler in their face at 21? I don't plan on getting anything else done to my face for a while (late 20s). I also really don't want to look overfilled at all.

TLDR: Am I too young to get filler in my chin? Will I need to do a lot of touch up in the future.
