I have a chubby cousin. 16 years old, her weight will reach 120kg. We often tell her that if we don't control our weight, we will definitely not get married in the future. When I was about 18 years old, I suddenly said that I would lose weight one day. We thought it was my favorite boy, so her mother enrolled her in a fitness class to lose weight. A year later, she did lose weight, but she showed us her skin. She said that the sequelae of losing weight are these white lines on her body. Because of these lines, her colleagues always make fun of her, saying that these lines on her body are all stretch marks and must have been born before.
In fact, these lines on her body are called fat lines, also called orange peel lines, which are common in buttocks, abdomen and inner thighs. The main reason is that the dermis in the middle layer of the skin loses its elasticity because of obesity, and this pale white line appears.
There is also a growth line, which is thicker than the fat line and appears as a short and rough sheet. Fat lines appear in the form of slender strips, so they are very different.
What are stretch marks? The so-called stretch marks are the patent of pregnant women. It grows from 4-5 months of pregnancy, but not all pregnant women will grow, and some pregnant women will not. Their abdominal skin is still very smooth after giving birth to the baby. The appearance of stretch marks is mainly the wavy lines caused by the stretching of abdominal skin, which breaks the elastic fibers and collagen fibers of the skin. The width and length of stretch marks are not fixed, and you can obviously feel the concave and convex feeling by touching them with your hands. Stretch marks will be particularly obvious during pregnancy, but will gradually fade after giving birth to the baby, and finally slowly fade into a white line.
Summary: By comparison, the lines, lengths and thicknesses of stretch marks, growth line marks and obesity marks are different.
