I got botox and filler in my jaw at Toxmi Gangnam about 3 years ago, and I still feel a foreign body sensation even though the filler is supposed to dissolve within a year. ㅠㅠㅜ I looked into the cost of dissolving the filler and they said it was 80,000 or 100,000 won. ㅜㅜ I sometimes get it dissolved because of the foreign body sensation, but I think it's right to think carefully before getting filler.
