The beauty cube hospital you mentioned is the earliest professional plastic surgery hospital in Dongguan, and now it seems to be the largest and most luxurious hospital. The hospital is quite formal, nipple reduction and plastic surgery itself has no side effects, but it must be done in a regular hospital!
The prosthetic breast augmentation done by a former colleague of mine is quite good. If the nipple shrinks, Dr. Tang is very good. I suggest you search their website and communicate with customer service staff online.
