Stretch marks are common skin changes that appear as a result of the skin being exposed to sudden stretching that exceeds its ability to adapt. They often occur during certain periods, such as pregnancy, puberty, or when gaining or losing weight quickly. They may also appear as a result of intense exercise that leads to muscle hypertrophy. These marks take the form of thin lines of varying color that appear in different areas of the body, the most important of which are the abdomen, thighs, breasts, and buttocks. Although they do not pose a health risk, many people are looking for ways to reduce their appearance due to the aesthetic discomfort they cause. 

What are stretch marks?

Stretch marks are fine lines that appear on the surface of the skin and resemble cracks or long lines. Their color usually starts out red or purple and then changes over time to become white or silver.

Causes of stretch marks

Stretch marks appear as a result of several reasons that lead to the skin stretching beyond its ability to adapt, causing the elastic fibers in its deep layers to rupture. The most important of these reasons are the following:

• Pregnancy: During pregnancy, the skin expands rapidly as the fetus grows, leading to the appearance of stretch marks, especially in the abdomen and breasts.
• Rapid growth in adulthood: During adolescence, rapid growth may occur in the body, leading to skin expansion and the appearance of marks, especially in males in the shoulder and back area, and in females in the pelvic and chest area.
• Rapid weight gain or loss: Rapid changes in weight lead to rapid expansion or contraction of the skin.
• Prolonged use of corticosteroids: Continuous use of creams or lotions containing corticosteroids can reduce collagen levels in the skin, making it less elastic and more susceptible to stretch marks.
• Genetic factors: Having a family history of stretch marks increases the likelihood of their appearance.
• Certain medical conditions: Certain health conditions, such as Cushing's syndrome and Marfan syndrome, can increase the risk of stretch marks due to their effect on skin elasticity and collagen production.
• Doing bodybuilding exercises: Increasing muscle mass quickly may lead to skin stretching and the appearance of these marks.
• Dry skin: Skin loss of elasticity due to dehydration may contribute to the appearance of stretch marks.
• Smoking: Smoking reduces blood flow to the skin and affects collagen production, which may increase the likelihood of stretch marks.

What are the symptoms of stretch marks?

Symptoms of stretch marks vary depending on the stage of their development, and are as follows:

• Early stage (recent signs): In this stage, the signs appear in pink, red, purple, blue, or black, and may be slightly protruding from the surface of the skin, and the person may feel itching or irritation in the affected area.
• Advanced stage (old marks): Over time, the color of the marks changes to white or silver, and they become less prominent and have a different texture from the surrounding skin. These lines may become slightly lower than the surface of the skin.

Stretch marks often appear in areas of the body that are subject to rapid stretching, such as the abdomen, breasts, hips, buttocks, and thighs. Although these marks do not cause pain or health problems, some may feel uncomfortable because of their appearance.
