I lightly got filler for neck wrinkles at a local clinic, but the filler marks were so severe that I visited to have it dissolved. Even though I had already had it dissolved twice, it did not dissolve properly, so I visited a Gangnam clinic known for filler. I was so stressed that I insisted on the head director no matter what. The price was 20% higher because it was the head director.
Overall, I am satisfied. I have not had filler re-treatment, so I do not know about that, but they really dissolve filler professionally and well. I recommend visiting for people like me whose filler treatment went wrong.
