This stratification is both vertical and horizontal. Once it appears, the face looks messy and has a clear sense of fault, which not only shows old age but also affects temperament. The loss and sagging of facial soft tissue caused by aging is a major cause of fault formation.
However, it is not necessarily aging that will cause this failure. If the facial bones of beauty seekers are relatively flat, the cheekbones are low, and the zygomatic arch is narrow, it is more prone to overall depression. If we observe carefully, we can find that this problem is not in the shape of risorius itself, but related to the whole facial soft tissue state and facial structure.
Many beauty seekers have different facial structures, such as high cheekbones or underdeveloped middle faces. This problem may be covered up by full facial soft tissue when the beauty seeker is young, and gradually exposed with the loss of facial collagen.
