Hello, has anyone has been to Nano plastic surgery in Gangnam? I am interested to have my revision rhinoplasty performed at Nano. I saw great results on their website and their reviews are great too but I couldn't find much information on the internet. I heard it's a popular local clinics specialized in revision. They do not do any advertising and their great reputation is through word of mouth. I appreciate if anyone can offer any insights. Thank you in advance!
