Is it February 17th this year? It's been 5-6 months since I got it. I got it from a domestic product, but I can't remember exactly what it was. I think it was Neuramis. The hospital said it would last about 6 months to a year. I don't think they do a lot of domestic products... I previously had a full face fat transplant and suffered from swelling that lasted for too long, but it really went away in less than 1-2 months... Even though it's only for one area, it's 6 months for this price. I felt like I would be so happy even if it went away, and I feel like I still have some left, so I'm quite satisfied. I also thought that the filler takes a lot of work from the doctor, so if it goes bad, it could fall out. I am satisfied with the maintenance period, but I felt like they were being too sloppy during the procedure, and honestly, the shape wasn't what I wanted, so I'm thinking of going to another hospital for a domestic product next time. Oh and!! This may be just my opinion, but I don't have a chin. But since I have a chin, I can't say anything... It feels like my chin stands out next to it?? At first, it looks very slim, but depending on the angle, the square jaw feels very full... So, I'm planning to get square jaw botox at the same time. Pebble chin Botox didn't seem to be necessary.
