Hi! I wish to have under eye fat repositioning to fix eye bags/ tear trough under my large eyes with a negative vector to my cheeks. It seems that surgeons in Korea use nano fat to restore volume under the eye and all over the face(nasal labial folds). Is this due to a difference in terminology in Korea? Nano fat in Western countries seems to be used only to improve skin texture, not to provide structural support, or have I misunderstood??
