There are dark red stripes on the inner thighs

When we feel that we are growing taller or gaining weight, we will find that our skin will also have some unexpected conditions. When the body's fat accumulates too quickly, some dark red scar-like things will appear on the inner thigh, which is prone to fat accumulation. It looks very ugly. We can choose to eat some collagen-rich foods or lose weight, because the root cause is fat accumulation.

This type of wrinkle is formed because the volume of bones, muscles or fat increases too quickly, exceeding the rate at which the skin can stretch, and the elastic fibers in the dermis are broken. This can be seen in people who gain weight too quickly, and it can also occur in many people during their growth spurts, even if the weight gain is not very noticeable. Even if you successfully lose weight and restore your original body shape, it will start out red, gradually darken over time, and finally turn into white stripes. If you use some drugs to increase skin elasticity and promote collagen growth during obesity or pregnancy, it may reduce or avoid the appearance of growth lines to a certain extent.

These are stretch marks, which are caused by growth and development. Many people have them and they do not affect health. In your case, you currently have stretch marks. When the red stripes disappear, white stripes will remain, which are called atrophic stripes. This does not affect health, and many children in their growth spurts have this condition. You can apply some Hirudoid or sodium heparin cream locally, or you can leave it alone. It is recommended to drink more water and eat fresh fruits, have three meals a day with balanced nutrition, avoid spicy, greasy and sweet foods, actively exercise to control weight, and apply olive oil or professional slimming cream locally for massage

It is mainly related to the rupture of skin elastic fibers caused by short-term weight gain or loss and strenuous activities.

The cause of skin atrophy lines is due to the breakage of fibers in the skin. There are usually two causes:

First, children in adolescence and developmental period grow too fast, mainly because the longest bone in the human body, the femur (thigh bone), grows too fast, while the skin and blood vessels cannot keep up with the speed of bone growth, resulting in the skin on the inner thigh near the thigh root and the skin near the knee being "torn" to form "earthworm"-like atrophy lines, which may be deep or shallow, depending on the individual situation. This is not a disease, but a normal phenomenon. It does not require treatment and cannot be treated. The second is "growing pains", which means that children in a period of rapid development will experience leg pain while sleeping at night, usually in the summer. This is caused by the muscles and blood vessels being pulled because they cannot keep up with the speed of bone growth.

The second cause is pregnancy in women, so they are also called "stretch marks". Due to the expansion of the abdomen, the skin on the abdomen and waist is torn, forming skin atrophy lines that cannot be repaired.

Another rare situation is that a very small number of women have large breasts, which causes the skin on the upper edge of the breast to be unable to withstand the long-term downward pulling force and results in slight atrophic stretch marks.
