What should I do about stretch marks caused by skin stretching due to weight gain?

When weight gain causes the skin to stretch and form stretch marks, the following measures can help improve the condition: 1. Reduce intake of high-calorie and high-fat foods, while increasing dietary fiber and water consumption. This helps control weight gain and prevent the formation of new stretch marks. 2. Establish a regular exercise routine that includes both aerobic activities and strength training, aiming for at least 3–4 sessions per week. This not only burns body fat but also enhances skin elasticity and support, helping to reduce the appearance of stretch marks. 3. Use skincare products containing ingredients such as vitamin E, centella asiatica, and cocoa seed butter. After bathing, apply them to areas prone to stretch marks and massage gently until fully absorbed. These ingredients help combat oxidative stress and inflammation, and promote collagen synthesis, thereby assisting in fading existing stretch marks.
