Stretch marks are swelling lines on the abdominal skin that occur during pregnancy. Long stretch marks can be remedied by medication, physical therapy, etc., and should be treated in accordance with the doctor’s instructions. Stretch marks have no adverse effect on the health of the human organism and can be left untreated. However, obvious stretch marks can last for a lifetime, affecting the appearance and causing mental stress to women, so those who have a need for treatment can follow the doctor’s instructions. For early stretch marks, retinoic acid can be used to increase the elastic fiber content in the stretch marks. Medications such as bitter almond oil and olive oil are also effective in fading and reducing stretch marks. Note that the use of retinoic acid is prohibited during pregnancy, and use during breastfeeding requires the cessation of breastfeeding. In addition, physical therapies such as laser treatment and radiofrequency technology can also be used to lighten stretch marks by improving the diseased tissues. Once stretch marks arise, it is usually difficult to eliminate them completely. Stretch mark repair products can also be used in daily life by consulting the doctor to make the marks fade away. At the same time, pregnant women should adjust their dietary structure during pregnancy to ensure that their weight grows at an even rate, and increase the elasticity of their skin through massage and skin care methods, which can also effectively prevent stretch marks. The method of removing stretch marks should be under the guidance of the doctor to choose appropriate and effective treatment, not to use the drugs to remove stretch marks on their own, so as not to cause skin damage or affect the fetus.
