Myeongdong jg facial contour (forehead + chin)

Anyone who has had facial contouring surgery at JG Plastic Surgery in Myeongdong or has come for a consultation.. I'm planning to get my forehead and chin done and I'm curious about it. I'm curious if they're good at it, and if it'll look bad.. I 'm also curious if the after- sales service is good^^ Is there anyone who got it done here? Or somewhere else ? I'm planning to get my chin done with rigid Gore-Tex, but I know Gore-Tex is more absorbent than silicone. Is it any good? Also, is osteotomy the best method for chin surgery? Would osteotomy be better or would an implant be better? My chin isn't that bad, but is osteotomy safer? Even if it's a short answer, please don't just ignore it and leave a comment or send me a message~^^ You guys will be blessed^^
