I got lip filler in November 2020 and lost a lot of it, so I got lip filler at ㅇㅋㅂ in October 2021. The price includes retouch as a condition of writing a review on the app, and I'm satisfied. If you ask for more, they'll add more. But my friend also got filler here, but he didn't get retouched, but with Jeon. There was almost no difference from before.
