Stretch marks are common skin swelling lines during pregnancy, mostly purple or light red, and irregularly distributed stripes, which are more common in women who are pregnant for the first time. As the fetus grows inside the pregnant woman, the abdomen expands significantly and the abdominal skin is overstretched, breaking the collagen and elastic fibers under the skin and creating a special type of scar. If stretch marks appear during pregnancy, they can be removed through massage, exercise and diet. Massage and moderate exercise can increase the elasticity of the skin and effectively reduce the appearance of stretch marks. In addition, you should also control your diet, eat less fatty foods and more protein, you can eat moderate amounts of collagen-rich foods, such as pig’s feet, and eat more fruits and vegetables rich in vitamin C. Some health care products can promote the regeneration of dermal fibers of pregnant women, increase skin elasticity and help to remove stretch marks, but you should not use the medicine at will, and should be applied under the guidance of a doctor to avoid adverse reactions to the body. In addition, pregnant women should strengthen skin care, you can apply collagen-rich essential oil or olive oil, if the effect is not satisfactory, you can remove stretch marks through medical cosmetic methods.
