I have not but I have heard amazing things. They have been in business for 25 years and there is a lot of information out there about them and the doctor. You can see pictures from patients and those include many caucasian women.
I always check for reviews with anything, especially things like this. Check on Google. Do a background check into the clinic. Make sure the doctor(s) on staff are board certified. If they seem hesitant to answer questions, avoid them!
I have gone to VIP International Plastic Surgery Center two years ago for nose correction and I had a fantastic experience. They provided both online and in person consultation. I planned ahead and made sure to meet the doctor before anything took place. For places that offer international care, they will or at least should have virtual consultations.
