This is me.
I got chin filler a total of 3 times at 6-month intervals, and
 it's been about 1 year and 6 months since I didn't get it, but it's still holding up well.
When you touch it, it feels like filler.

But the problem is,
 when I am in bad condition and tired, my chin becomes stiff and swells like Choi Hong-man's chin.
This symptom has happened about twice recently.
The swelling persisted throughout the day and disappeared the next day.

Why do these side effects occur??

I don't remember what company the product was, but
 all three fillers were domestically produced.
