Stretch marks are a pregnancy phenomenon that occurs when the skin elastic fibers break down during pregnancy as the uterus gradually increases in size. Most of them appear on both sides of the abdomen, inner thighs and, in severe cases, on the chest and buttocks. In the early stage, there are a lot of purple or light red irregular parallel and slightly depressed stripes with a slight itching and tugging sensation, which are seen in first-time mothers. After childbirth, with pigment loss and atrophy, the old stretch marks are silver or white scars shiny, seen in menstruating mothers. I, the mechanism of the production of stretch marks is still unclear, may be related to the following factors: 1, during pregnancy adrenocorticotropic hormone secretion of glucocorticoids, the hormone secretion of elastin, so that the elastic fibers denaturation, coupled with the increase of the uterus to increase the skin tension of the abdominal wall of pregnant mothers, resulting in the elastic fibers of the skin break. 2.Excessive weight gain. 3, genetic factors. 4, advanced age, poor skin elasticity and dry skin. However, not every pregnant woman will have stretch marks, and the severity varies from person to person, which may be related to personal constitution. Stretch marks do not have adverse effects on the body and can be left untreated, but they can greatly affect the aesthetics, which is unbearable for beauty-loving mothers. Second, what are the hazards of stretch marks? 1, itchy skin, triggering rashes; 2, loose skin, folds; 3, causing sagging breasts; 4, fat accumulation. Third, stretch marks itchy what to do?
