Hello, this is a stretch mark. Moderate massage is recommended. For stretch marks and obesity lines, local massage with essential oil and professional slimming products can increase skin elasticity. When used together with wrinkle cream, it not only makes the massage easier, but also keeps the skin moist and avoids excessive and intense pulling. However, for pregnant women, it is recommended to insist on abdominal massage from the third month of pregnancy to the third month after delivery, which can effectively prevent the formation of stretch marks or dilute the fine lines that have been formed.
