The original cracks in the skin gradually faded and finally turned silvery white. The formation of stretch marks is mainly due to the influence of pregnancy hormones. Abdominal swelling damages or destroys the elastic fibers and collagen fibers of the skin, making the abdominal skin thinner and thinner.
At present, the causes of stretch marks are not clear, and the changes of skin tension and hormones during pregnancy are considered to be the main causes of stretch marks. The occurrence of stretch marks is related to the age of pregnant women, genetic factors, family history, skin type, pre-pregnancy weight, weight gain during pregnancy and other factors.
The formation of stretch marks is mainly due to the influence of pregnancy hormones. In addition, the swelling of the abdomen damages or breaks the elastic fibers and collagen fibers of the skin, and the abdominal skin becomes thinner and thinner, and some pink or purple wavy lines with different widths appear.
After delivery, these patterns will gradually disappear, leaving a shiny white or silver scar line. Skin lesions often occur in the breast, abdomen, buttocks and thighs. Occasionally there will be itching, burning pain and other symptoms.
