The formation mechanism of stretch marks

The formation of stretch marks is mainly due to the influence of hormones during pregnancy.

After delivery, these patterns will gradually disappear, leaving behind white or silvery shiny scar lines, also known as stretch marks. Stretch marks mainly appear on the abdominal wall, and may also appear on the inner and outer thighs, buttocks, chest, lower back and arms. This is most obvious in primiparas. Once stretch marks appear, they will not disappear and will be accompanied by sagging skin, sagging breasts, and accumulation of abdominal fat, which will seriously affect women's body shape and physical and mental health after childbirth.

* Caused by hormonal changes during pregnancy.

* The subcutaneous tissue is stretched and ruptured: With the expansion of the uterus, the growth of the fetus and the increase of amniotic fluid, the abdomen of the pregnant woman will swell rapidly. At this time, the epidermis and dermis can keep up with the speed of extension, but the subcutaneous tissue cannot keep up with the speed of abdominal expansion, causing the collagen fibers and even elastic fibers rich in the subcutaneous tissue to be unable to withstand the expansion and rupture. This can also happen with rapid weight gain and loss, when the body changes too much volume in a short period of time.

* Influence of physical constitution: Many mothers will have a lot of stretch marks like their mothers and sisters; some people have extremely smooth belly and do not get stretch marks, this is related to physical constitution.
