Facial aging was once thought to be the result of the relentless downward pull of gravity on skin and underlying fat. In turn, facial fat was believed to be a contiguous sheet of tissue. However, over the past four decades, a number of investigators have examined more closely the causes of facial aging, leading to a better understanding of age-related changes, and have confirmed and further explored the proposal by Gonzalez-Ulloa and Flores in 1965 that facial aging involves changes in muscle and bone, as well as skin and fat. Further, the recent work of Rohrich and Pessa (and other authors) has demonstrated that facial fat is not a sheet of tissue, but rather is compartmentalized throughout the face. This discovery has allowed the evolution of improved techniques for facial rejuvenation.
人们曾一度认为，面部衰老的原因是重力对皮肤和皮下脂肪的持续牵拉。反过来，人们又认为面部脂肪是一层连续的组织。然而，在过去的四十年里，许多研究人员更仔细地研究了导致面部衰老的原因，从而更好地了解了与年龄相关的变化，并证实和进一步探讨了 Gonzalez-Ulloa 和 Flores 在 1965 年提出的观点，即面部衰老涉及肌肉和骨骼的变化，以及皮肤和脂肪的变化。此外，Rohrich 和 Pessa（以及其他作者）的最新研究表明，面部脂肪并不是一层组织，而是分布在整个面部。这一发现使面部年轻化的技术得到了改进。
