Dean Park Zhang-you pointed out that if angel eye (lifting) and reduction are done separately, there are three incision sites: lifting two incision sites (ordinary lifting needs five incisions above the forehead to achieve the lifting effect, while lifting in Kailunxiu Hospital, that is, angel eye surgery, has only two incisions less than 2 cm with the help of endoscope)+reducing along the hairline. However, if two operations are performed together, only hairline can be cut, and it can only be cut at 1.
