Teenagers grow tall quickly, but they leave red lines with purple marks on their backs and hips, and then gradually turn into white lines. Dermatologist Zhao Zhaoming said that in adolescence, because they grow fast, it happens on their backs and buttocks, which is called growth line. Growth line is a kind of skin expansion line, and others such as stretch marks and atrophy lines are also skin expansion lines.
Growth line Zhao Zhaoming said that modern people have good nutrition and grow fast, and the incidence of growth lines is higher than before, especially in armpits, crotch, buttocks and waist. Teenagers, whether tall or fat, may grow beyond the growth line as long as they grow excessively. Growth lines can usually be judged by naked eyes, and there will be many red stripes at a time, which may also occur on the back and thighs. The growth line will appear red with a little purple at first, and then gradually turn white. It itches in hot weather, but it doesn't hurt.
Hong Miaoqiu, director of the Department of Children's Infection in Taipei Veterans General Hospital, said that the cause of growth line is still unclear, which may be related to genes, hormones, development and physique, and has less genetic relationship, so it is impossible to predict who is the high-risk group of growth line.
The growth line can't be effectively treated, so children are advised not to eat supplements indiscriminately. Zhao Zhaoming said that the growth line is a kind of scar tissue formed by dermal injury and will exist forever. Eating collagen will not help prevent or treat growth lines. He suggested applying moisturizing lotion and high-oil moisturizing products, so that the surface of the growth line will be smoother and the lines will not be too deep. Hong Miaoqiu said that there is no effective treatment for growth line. If it affects the appearance, you can consider laser treatment or local application of an acid to dilute the traces, but it cannot be completely eliminated.
Although the growth line cannot be prevented, doctors advise children and teenagers not to take supplements at will. Some tonics promoted in the workshop can make children grow tall, strong and fast, and it is best to touch them less. Zhao Zhaoming said that it is good to let the growth rate be based on age, and the diet should be balanced, and no additional nutrients should be added. Director Hong Miaoqiu also suggested that normal diet and exercise are good for developing children. In case of growth line, it is also recommended to face it with a normal heart.
