In both exposed and protected areas of progressively older people the underside of the epidermis becomes increasingly flattened out. This flattening is accompanied by a comparable rarefaction of the superficial blood vessels. In this article we review the architecture of the elastic fiber framework in the papillary dermis of skin protected from the sun; aging changes that occur are similar to, but less severe than, those in sun-exposed areas. Most cutaneous sensory end organs are little affected by aging; those in the external genitalia, however, and particularly those underneath the vaginal epithelium become smaller and some disappear.
在年龄逐渐增大的人群的暴露部位和非暴露部位，表皮下层都变得越来越扁平。这种扁平化伴随着浅表血管的相应稀疏。在本文中，我们回顾了免受阳光照射的皮肤乳头层真皮中弹性纤维框架的结构；发生的衰老变化与暴露于阳光下的区域相似，但程度较轻。大多数皮肤感觉终末器官受衰老影响较小；然而，外生殖器的感觉终末器官，尤其是阴道上皮下方的那些，会变小，有些甚至消失。
