Because after all, she is a female star, and she is really fat and thin for fun, so she often loses a lot of weight suddenly, or occasionally gains weight for a few days, which may cause her skin to be unable to adapt completely at once, so she will relax.
Female stars can't stand loose skin. After all, they have to live under the camera every day, and there can't be any imperfections. We must find a solution. To tell the truth, we are not close to her, so maybe we can only guess. According to our own experience, losing weight is something that everyone will experience.
So according to my own experience, I will exercise first. Everyone knows that exercise can shape and tighten loose parts, so exercise is definitely the first choice, but the effect brought by exercise is slow and takes a lot of time, whether in the middle of this process or after successful maintenance.
So exercise is the main thing, so there must be other ways to assist. We may not be able to imagine the specific method, but we can probably guess that some relatively high-tech beauty instruments can help the skin to be firmer, which is the same as what some beauty salons put forward to make your face feel more upward.
So combining these two should be the method that female stars will do. After all, stars are just ordinary people, right? It is really impossible for any magic to get better at once, so it takes hard work to become beautiful. Female stars are like this, and so are we ordinary people.
