What are growth marks, how old are growth marks, and why do they grow

Growth streaks are irregular streaks that appear on the human body or tortoise shell. In the process of captivity, due to the rapid growth rate of tortoises, the shields of the outer armor begin to expand between the shields, and the pigments in the middle have not had time to form, and white or pale yellow and pale pink lines will appear.

After a period of time, as the pigment increases and keratin is formed, the growth lines (lines) will slowly disappear. But as the tortoise grows, it will still appear. The constant appearance of growth lines (lines) indicates that your turtle is growing, which is a manifestation of health.

We will find that some people will have something like scratches on their bodies, but some people will not have them. This thing is what we call growth streak. So at what age do growth streaks usually grow?

Growth marks are not common to everyone, which is related to personal physique and body growth rate. Growth marks, so to speak, appear when they develop and grow from puberty. Generally speaking, between the ages of 9 and 20, it is a normal physiological phenomenon that growth marks are produced during the growth and development of the body.

In addition, there are still some special circumstances, there are genetics, and people who have used growth hormone are also prone to growth lines.

The reason for the growth of wrinkles is that because the body grows too fast in a short period of time, the elastic fibers cannot withstand excessive stretching, and there will be fracture and damage, and white, red, purple and other different colors of lines will be formed. Generally speaking, growth marks are mainly distributed on the arms, legs and abdomen. In addition, when the body's fat and thinness changes and the height is basically stable, the growth lines will no longer change, and will gradually turn white and slowly fade.

Therefore, friends can usually supplement various nutrients, live a regular life, maintain sufficient sleep to help improve this condition, and can also carry out an appropriate amount of massage to improve and alleviate growth lines.

Stretch marks are also known as stretch marks, which are mainly caused by the body's excessive secretion of adrenal hormones, which causes the elastic fibers of the body skin to be broken down by proteins.

This condition will lead to the skin elasticity or abrasive deterioration, resulting in the breakage of elastic fibers, resulting in the extension of the surface of the skin, resulting in excessive stretching into growth marks.

Adolescent men and women, and overweight adolescents are prone to growth marks, which often grow on the buttocks, lower back, thighs and other parts.

Some people don't know whether they have growth marks or obesity marks on their body, but the appearance of lines will affect the beauty of the human body. In the crowd, there are many people who have growth lines, and they are in a very exposed position, which makes many people afraid to wear fashionable and beautiful clothes. So, in the early stage of growth streaks**, what do growth streaks look like?

Growth marks can be called striae swells, which is due to the excessive secretion of the human adrenal glands, and the cortex of the adrenal glands can secrete a kind of glucocorticoid, which decomposes the elastic fiber protein in the human body into sugars, so that the elastic fibers in the body are denatured. Glucocorticoids can also inhibit the proliferation of fibroblasts in the human body, so that the elastic fibers in the human body are broken. If the volume of bones and muscles in the human body and their fat increase more than the rate of extension, then the elastic fibers in the body will be pulled off, resulting in the appearance of lines.

Growth streaks appear as pale red lines in the early stage, and there are many irregular lines on the human body. In fact, not everyone will have growth lines. This has something to do with the person's physique and the speed of growth.

In adolescence or obese people, the probability of occurrence is relatively high, and it will not affect the body. It is also possible if it is a person who is in **, because the rapid ** will cause the body to not be able to react, resulting in white streaks, which are difficult to eliminate.
