What should be done about loose skin after a fat person loses weight?

For overweight individuals who experience loose skin after weight loss, the following measures can help improve the condition: 1. Dietary adjustments: Increase intake of foods rich in vitamins and collagen, such as pig trotters, chicken feet, and beef tendons, which help enhance skin elasticity. 2. Exercise: Engage in regular aerobic activities such as running, swimming, and yoga, which effectively improve skin elasticity and promote tightening of loose skin. 4. Skin care: Use skincare products containing vitamin E or apply vitamin E preparations to the abdomen to nourish and maintain the skin, improving firmness and elasticity. 5. For patients with particularly severe skin laxity, cosmetic surgical procedures such as a facelift or body lift may be considered. Please choose the appropriate method based on your individual situation and proceed under the guidance of a qualified medical professional.
