It should be effective, but we should pay attention to several points. Plastic wrap is airtight after all, and the time should not be too long, otherwise it will easily lead to skin diseases for some sensitive skin; It's not that you can thin your legs by wearing plastic wrap, but you need exercise. You will sweat when you exercise, and the role of plastic wrap is to promote the discharge of sweat. After exercise (keep it for more than 30 minutes, because the body starts to consume fat after 30 minutes, and the previous exercise only discharges water), take off the plastic wrap in time and wash off the sweat with cold water, which will be good for your skin. . .
