Breast augmentation in Korea - implant brands and recommendations?

I am planning to get breast augmentation in Korea. I know that Korean surgeons typically aim for more natural-looking results compared to Western preferences. What implant brands are commonly used in Korean clinics? I have heard of Motiva, Mentor, and Bellagel. Are there differences in quality and safety between these brands? I am looking for a natural teardrop shape rather than very round. What size is typically recommended for someone who is 165cm and 52kg? Also, is the surgery typically done under local or general anesthesia in Korea?
