Stretch marks are mainly due to the hormonal effects of pregnancy and the bulging of the abdomen, resulting in damage or breakage of the elastic and collagen fibers of the skin, thinning and thinning of the abdominal skin, and the appearance of wavy patterns. After childbirth, these patterns will gradually disappear, leaving behind white or silvery-white shiny scar lines, known as stretch marks. Eat more collagen and vitamin-rich foods, such as soybean and pig’s feet soup, peanuts, red dates, fruits and vegetables, etc. In addition, you can also do appropriate exercises, such as housework, yoga, swimming, etc., to increase the elasticity of the skin. You can apply olive oil to your abdomen and insist on massaging your abdomen in a clockwise direction starting from your belly button every day. You can not choose professional stretch mark removal products for relief. If the symptoms are severe, they can be treated with oral work topical medications, or they can be relieved by laser or electrotherapy to narrow the folds by rearranging the collagen fibers. Stretch marks can also be treated by performing abdominoplasty to remove excess skin and fat. Stretch marks are important to prevent, and once formed they are difficult to eliminate. Establish a balanced nutrition during pregnancy, avoid excessive obesity, and should also adhere to daily exercise.
