I did it at ㅇㄹㅍ, twice, once a year, and the results were great! There are bad cases where the thread comes out, but ㅇㄹㅍ is thought to be safer because it is a procedure that is inserted inside the nose and mouth! But honestly, it feels really bad, it hurts, and it may not be an easy procedure, but the effect seems to last for about a year - I think it gets worse after about 11 months. At first I thought there was no difference. But I didn't tell my family, but one day my mom said, "Why does it look like you had surgery on your nose?" Since you said so, it seems to be effective! However, if you keep putting in too much thread, it can clump up and become dull... I think it may be difficult to make it a permanent solution. Nose surgery is scary, but I wonder if it should be done. For now, I'm satisfied!
