Abstract：
It is important to understand that each layer of facial tissue, from the underlying facial skeleton to the overlying skin, undergoes significant changes during the aging process. Bony support is lost along the mandible and maxilla and the orbital aperture widens. Superficial and deep fat pads undergo volume loss and migration and the overlying skin begins to reveal signs of both intrinsic aging with skin laxity and fine rhytids as well as extrinsic aging in the form of coarse, deeper rhytids and dyspigmentation.
摘要：
重要的是要了解面巾纸的每一层，从下面的面部骨骼到上面的皮肤，在老化过程中发生重大变化。骨支撑沿着下颌骨和上颌骨丢失，并且眼眶孔变宽。浅层和深层脂肪垫经历体积损失和迁移，上覆的皮肤开始显示出内在老化的迹象，皮肤松弛和细纹，以及外在老化的形式的粗糙，更深的韵律和色素沉着。
