As for chin filler, I always only got Restylane filler (in the case of the chin, no matter how much it goes in, it always ends within 2cc to 3cc). Restylane lasts longer than other fillers, so I got it, but I wasn't sure, so I tried a domestic filler this time, and it's okay. To be honest, what's the difference ? I don't know. Don't be too scared. Just make your choice.
