What is stretch mark

Research shows that human skin is mainly composed of collagen and elastin(stretch mark removal machine). Their most basic unit is amino acids. These amino acids are arranged neatly and closely to form a network structure. This network makes the skin have hardness and toughness, and maintains a certain tension and stretching force. Medical experts found that the reason for pregnancy is that the adrenal gland secretes a large amount of glucocorticoids during pregnancy, which increases the brittleness of this net. When a woman is pregnant for more than 3 months, the enlarged uterus protrudes from the pelvic cavity and develops into the abdominal cavity. The abdomen begins to swell, and this net begins to stretch.

Especially after 6 months of pregnancy(stretch mark removal machine). When it exceeds a certain limit, it will cause the fracture of the net. There will be pink or purplish red irregular longitudinal cracks on the broken surface on the skin, which is stretch marks. After delivery, the cracks on the skin gradually fade and finally turn silver white.

The caesarean section directly cuts the amino acid net(stretch mark removal machine). When it heals, the broken points on the net are disorderly adhesion, forming itchy and ugly scars. Stretch marks and cesarean section scars are skin injuries. Once they are formed, they cannot repair themselves without the help of external forces
