Red and white obesity lines are the expression of obesity lines at different times. Usually, the initial color of obesity lines is red, and will gradually change to white over time, and there is no saying which is more serious. Obesity lines are usually formed when the skin is lengthened rapidly due to excessive weight gain and the skin elastic fibers become degenerate and fragile and are pulled off. Obesity lines are red at first, at which point medications such as vitamin A acid cream can be applied to increase the elastic fiber content of obesity lines and assist in improving them. If no treatment is carried out, the red obesity lines will gradually turn white. Once the white obesity lines are formed, it is more difficult to remove them, and laser treatment can be continued for 6 months or longer to assist in improving the symptoms, but it is more difficult to remove them completely. Therefore, beauty lovers should actively carry out treatment after finding red obesity lines, and waiting for the red obesity lines to turn white before carrying out treatment will increase the difficulty of treatment and the treatment effect is not good. In addition, the patient should also control the diet to avoid rapid weight growth to avoid producing new obesity lines and increasing the difficulty of treatment.
