I received 8cc filler treatment at a dermatology clinic in Hwanggeum-dong, Suseong-gu, Daegu. They gave me an anesthetic injection while wiping my face without washing my face, and then injected the filler while wiping it roughly. The needle pricked me a lot and it hurt to a certain extent, so it was very difficult and painful, so I will do the rest later. I said I would get it and asked how many ccs I had left. Both the doctor and the nurse said I got a total of 5 ccs and that I had 3 ccs left, so I should schedule my next appointment. So I made a reservation, but since I was busy, I made an appointment almost 3 weeks later. After a while, I went to the hospital again and asked if I had 3 ccs, and they said no. He changed his mind and said that there were 2 cc left. When I said no, he clearly said that there were 3 cc left, the doctor showed me his computer and showed me a text saying that there was 2 cc left. I was dumbfounded, but he said yes, and there was no evidence, so it was okay even though it was unfair. The remaining filler was used again on the forehead and temples. As for the injection, they skipped washing the face and injected anesthesia and filler while wiping. I asked if they could do it while wiping, and they said I could do it while wiping. Then, they started poking me here and there,,, saying that I have to prick a lot to straighten the skin? Anyway, he pricked me mercilessly and took a picture. When the swelling and bruising disappeared, I looked in the mirror and saw that there was a 2cm dent in my right forehead above my eyebrow. I called the hospital, made an appointment, and came back. The doctor said it was not a dent, but a reflection. ,,, It’s not lifting and the filler may show through? This was the first time I noticed it. Anyone can see that there is a dent in it, but you are saying that it is transparent. I kept saying no, so he said that only that part could be filled in and advised me to put in 1cc more. But he said that I would have to pay for that 1cc. ,,, Money wasn't the issue, but I was very upset by his attitude. So he said it was okay and said that if he was going to pay, he would pay somewhere else and get fillers done elsewhere. After thinking about it carefully, I felt very upset. I paid almost 900,000 won to get fillers. But does it make sense that I don’t know exactly how many cc I injected into my face??? I wondered if they didn't put in the correct amount of filler and just pricked it with a needle,,, I wonder if all dermatology post-treatment is like this,,, I thought it was a waste of money, and my head got confused. The same thing happened to me. Always check the amount of filler to avoid damage!!!! Be sure to check how many ccs are injected!!!!!,,, And if you know if there is a see-through phenomenon with fillers, please let me know. Thank you.
