How many months do stretch marks begin to appear?

Under normal circumstances, the collagen fibers in the skin and the abdominal muscles maintain a certain elasticity, so they can be freely contracted within a certain range, so it is not easy to form wrinkles. When a woman is pregnant for more than three months, the enlarged uterus protrudes from the pelvis and moves toward the abdomen. As the fetus continues to grow and develop, the abdomen continues to swell, the skin collagen fibers and waist muscles begin to stretch excessively, and as the pregnancy week increases, many fiber cells in the subcutaneous tissue are finally "torn apart". After the 6th month of pregnancy, the abdomen bulges rapidly. At this time, the collagen fibers in the skin gradually break down, and stretch marks become more obvious.

In fact, the growth of stretch marks varies from person to person. According to the different physical conditions of pregnant women, the time when stretch marks begin to grow will also be different. But generally speaking, pregnant women will begin to see stretch marks during the 5th to 6th month of pregnancy, usually appearing in the thighs and abdomen. Due to the different elasticity of pregnant women's skin, some pregnant women will not develop stretch marks until the late pregnancy or even a month before delivery, and some pregnant women may not have stretch marks even during the entire pregnancy. This is all normal.

1. Prevention before pregnancy: Women who plan to become pregnant should exercise before pregnancy, do more aerobics, and massage the abdomen more often, which can effectively improve the elasticity of the waist muscles and skin. You should also eat more protein-rich foods on a regular basis, which is beneficial to improving the skin's beauty and enhancing the skin's repair ability. Improving abdominal muscle tension, such as doing push-ups, can also effectively reduce the chance of fiber cell rupture.

2. Prevention during pregnancy: During the entire pregnancy, pregnant women should consciously control their weight gain rate. Gaining weight too quickly can easily increase the probability of stretch marks. After three months of pregnancy, pregnant women can use olive oil to prevent stretch marks. Apply olive oil to the thighs and abdomen every night and massage for 5-10 minutes, which can effectively prevent the formation of stretch marks. Pregnant women usually don't need to scratch their itchy abdomen vigorously, because scratching will damage the structure of dermal fiber cells. At the same time, they should avoid taking baths.

Stretch marks are mainly caused by the outflow of collagen powder from the human body and the rupture of collagen fibers. Therefore, in terms of proper diet, pregnant women should eat more foods rich in collagen during pregnancy, such as fish fillets, pig's feet, etc., to improve skin elasticity and reduce the growth of stretch marks. You should also control sugar intake, eat less foods with high melanin content, and eat more fiber-rich vegetables, fruits, and foods rich in vitamins and minerals, which will help increase the permeability of cytoplasm and the metabolic function of the skin.
