I found this place while looking for somewhere in Busan that could do lip and lip-corner filler naturally, and it seemed like they were trying to make it as close as possible to the look I wanted rather than something overdone and flashy.
I went for a consultation and they explained the types they use and the anesthesia method. I brought photos of the lip shape I wanted, which made the consultation easier, and I was glad I could explain my preferred look more clearly. They also looked at the shape and volume of both the upper and lower lips, and even how they would look when the lips are apart.
