The fall-off in ovarian production of estradiol tends to accelerate skin ageing, just as it accelerates bone and vascular ageing. The absence of progesterone increases the impact of the androgens on the sebaceous glands, the body hair and hair on the head. The absence of estradiol slows the mitotic activity of the basal layer ot the epidermis, reduces the synthesis of collagen and probably that of elastic fibers. It contributes to the thickening of the general dermoepidermal junction and the degradation of the mechanical properties, notably of resistance of shocks. General hypoestrogenemia may be spontaneously attenuated by the local synthesis of estradiol in the adipose tissue. Estrogen treatment should be prescribed at a sufficiently high dose to be truly substitutive in order to produce a measureable effect.
卵巢雌二醇分泌量的下降往往会加速皮肤衰老,就如同它会加速骨骼和血管衰老一样。孕酮的缺乏会增强雄激素对皮脂腺、身体毛发和头部毛发的影响。雌二醇的缺乏会减缓表皮基底层的有丝分裂活动,减少胶原蛋白的合成,可能还会减少弹性纤维的合成。它会导致整个真皮表皮连接处增厚以及机械性能退化,尤其是抗冲击能力下降。全身性低雌激素血症可能会因脂肪组织中雌二醇的局部合成而自发减轻。雌激素治疗应以足够高的剂量进行处方,以达到真正的替代效果从而产生可测量的作用。
