采用光学显微镜（LM）和扫描电子显微镜（SEM）对6名老年人（67-82岁）的皱纹进行了观察。有两种类型的皱纹。一种是在暴露于阳光下的皮肤上产生的深皱纹，并且在拉伸时不会消失（永久性皱纹）。光镜和扫描电镜显示皱纹区真皮上层的弹性组织变性较周围组织变性少。另一种类型是浅皱纹，在防晒皮肤上形成，在拉伸时消失（临时皱纹）。光镜和扫描电镜显示真皮乳头层弹性纤维减少或消失，与老化皮肤相似。
Wrinkles in six aged persons (67–82 years of age) have been investigated by light microscopy (LM) and scanning electron microscopy (SEM). There are two types of wrinkles. One is a deep wrinkle which develops on the sun‐exposed skin and does not disappear on stretching (permanent wrinkle). The LM and SEM showed less elastotic change in the upper dermis in the area of wrinkle than in that of the surroundings. The other type is a shallow wrinkle which develops on sun‐protected skin and disappears on stretching (temporary wrinkle). The LM and SEM showed the decrease or loss of the elastic fibres in the papillary dermis as seen in ageing skin.
