Look at the picture. Think about the shriveled lines. Have you ever lost weight? That is, I am already fat, and there is more fat in this part. Then I lost weight for a short time? Or is there more intense exercise? Or take glucocorticoid for a long time? Look at the picture and consider the wrinkle, also known as growth line, which is a stripe that appears when the skin contracts after the subcutaneous fat is reduced or redistributed. Generally, it will not have any impact on the body and does not need special treatment.
