Factors of skin laxity caused by elderly childbearing

With the development of the times, more and more women choose to postpone the childbearing age. However, the elderly childbearing has brought many health problems, one of which is skin laxity. The following will elaborate on the factors of skin relaxation caused by aging and childbirth from four aspects.

1. Collagen decrease

Collagen is one of the main ingredients of the skin, which can maintain the elasticity and firmness of the skin. However, with the growth of age, the production of human collagen gradually decreases. For the elderly women who give birth, the rate of collagen reduction is accelerated due to the older childbearing age. This leads to skin relaxation and wrinkles.

In addition, changes in female hormone levels during pregnancy will also have a certain impact on the production of collagen. Estrogen is an important factor to maintain the normal production of collagen. After pregnancy, estrogen level will fluctuate, which will affect the synthesis of collagen and lead to skin relaxation.

2. Damage of skin elastic fiber

In addition to collagen, there are other elastic fibers in the skin, such as elastin. These elastic fibers can keep the skin elastic and tight. However, the production of elastic fibers in the skin of elderly women due to their old childbearing age is reduced, and the aging speed is accelerated.

In addition, the appearance of stretch marks during pregnancy will also lead to the destruction of skin elastic fibers. During pregnancy, the skin is under the pressure of expansion, which causes stretch marks. These stretch marks not only destroy the elastic fibers on the skin surface, but also further accelerate the relaxation of the skin.

3. Decreased adipose tissue

Due to the growth of age, the metabolic capacity of the body of elderly women who give birth decreases, and the adipose tissue gradually decreases. Adipose tissue plays an important role in maintaining the plumpness and firmness of skin. When adipose tissue decreases, the skin will appear slack and sagging.

In addition, due to weight gain during pregnancy, adipose tissue will be redistributed, especially around the abdomen and breast. When the weight returns to normal after pregnancy, the reduction of adipose tissue will also lead to skin relaxation.

4. Muscle strength decreases

The muscle strength of elderly women who give birth gradually weakens as they grow older. Muscles play an important role in maintaining skin firmness and lifting. When muscle strength weakens, the skin of breast and other parts is prone to relaxation and droop.

In addition, older women who give birth need to spend more energy during pregnancy and childbirth, which further accelerates the weakening of muscle strength and increases the degree of skin relaxation.

Summary

The causes of skin relaxation caused by aging and fertility can be summarized as the reduction of collagen, the destruction of skin elastic fibers, the reduction of adipose tissue and the weakening of muscle strength. These factors interact with each other, making women who have given birth at an advanced age more prone to skin laxity. Therefore, for women who plan to give birth to the elderly, reasonable skin care, balanced diet, moderate exercise and other measures are very important to slow down the degree of skin relaxation and maintain a healthy young appearance.
