A woman's skin is dramatically affected by pregnancy. Its biomechanical properties are critical for resisting highly stressed areas. The aim of this work was to evaluate the impact of pregnancy on the mechanical properties of skin, as well as to evaluate the imprint that pregnancy leaves on the skin after delivery.
Suction tests using a cutometer were performed on 15 non-pregnant women and 26 pregnant women at 8 months of pregnancy and 4 months after delivery. Areas of abdomen and thighs were studied.
Significant differences between the non-pregnant and 8-month pregnant groups were observed. Our data demonstrate that skin becomes less elastic and less deformable on the abdomen during pregnancy. On the thighs, a loss of elasticity and firmness was also observed. At 4 months after delivery, the skin did not return to its initial state.
This study showed that the mechanical properties of skin changed drastically during pregnancy compared to the non-pregnant condition and that these properties remain altered 4 months after delivery. In addition to alterations in abdominal skin during pregnancy, we also observed mechanical changes on the thighs, which are less subject to stretching.
女性的皮肤在孕期会受到显著影响。其生物力学特性对于抵抗高应力区域至关重要。本研究的目的是评估孕期对皮肤力学性能的影响，以及评估分娩后孕期在皮肤上留下的印记。
对15名未怀孕女性以及26名怀孕8个月和分娩后4个月的孕妇，使用皮肤弹性测定仪进行吸力测试。研究了腹部和大腿部位。
观察到未怀孕组与怀孕8个月组之间存在显著差异。我们的数据表明，孕期腹部皮肤的弹性和可变形性降低。在大腿部位，也观察到弹性和紧致度的丧失。分娩后4个月，皮肤未恢复到初始状态。
本研究表明，与未怀孕状态相比，孕期皮肤的力学性能发生了巨大变化，且这些性能在分娩后4个月仍未恢复。除了孕期腹部皮肤的改变外，我们还观察到大腿部位的力学变化，大腿部位较少受到拉伸。
