Cutaneous ageing manifests itself as a progressive reduction in function and reserve capacity of skin tissue. Collagen atrophy is a major factor in skin ageing. There is a strong correlation between skin collagen loss and oestrogen deficiency due to the menopause. Skin ageing is associated with a progressive increase in extensibility and a reduction in elasticity. With increasing age, the skin also becomes more fragile and susceptible to trauma, leading to more lacerations and bruising. Furthermore, wound healing is impaired in older women. Oestrogen use after the menopause increases collagen content, dermal thickness and elasticity, and it decreases the likelihood of senile dry skin. Large-scale clinical trials are necessary to help make informed recommendations regarding postmenopausal oestrogen use and its role in the prevention of skin ageing. Oestrogen has profound effects on connective tissue turnover, no matter the site. It has been shown that menopause has similar effects on the connective tissue of the carotid artery media, intervertebral discs and bones.
皮肤老化表现为皮肤组织功能和储备能力的逐渐下降。胶原蛋白萎缩是皮肤老化的主要因素。皮肤胶原蛋白流失与绝经导致的雌激素缺乏之间存在密切关联。皮肤老化与伸展性的逐渐增加和弹性的降低有关。随着年龄的增长,皮肤也变得更加脆弱,更容易受到创伤,导致更多的撕裂伤和瘀伤。此外,老年女性的伤口愈合能力受损。绝经后使用雌激素可增加胶原蛋白含量、真皮厚度和弹性,并降低老年性干性皮肤的可能性。需要进行大规模临床试验,以帮助就绝经后雌激素的使用及其在预防皮肤老化中的作用做出明智的建议。无论在哪个部位,雌激素对结缔组织更新都有深远影响。研究表明,绝经对颈动脉中层、椎间盘和骨骼的结缔组织有类似影响。
