I got lip filler at Seoul Center because my lips are quite thin and dry. The doctor provided a very thorough consultation, showing me the lip shapes that would suit my face before proceeding with the injection. During the injection, it wasn't very painful, just a slight sting. After about 3 days, my lips started to take on a beautiful, natural shape, without looking like I had just had filler. A plus is that the doctor injected very evenly, with no asymmetry or swelling at all.
