Stretch Marks

What Are Stretch Marks?

Stretch marks, medically known as striae, are streaks or lines that appear on the surface of the skin due to rapid stretching or shrinking. Initially, they may be red, purple, or pink and often fade to a silvery white over time.

Although they are completely harmless and don’t pose any health risks, some people may feel self-conscious about them and seek ways to reduce their appearance.

Symptoms

Discoloured Streaks: Stretch marks typically start as red or purple streaks on the skin and gradually fade to a silvery white. They remain visible even after fading.
Indentations or Raised Marks: Depending on the severity, some stretch marks may be deep and indented, while others might appear slightly raised.
Itching or Discomfort: In some cases, stretch marks can cause itching or mild discomfort, especially when they are newly formed.
Common Areas: Stretch marks usually appear in areas where the skin undergoes significant changes, such as the abdomen, thighs, hips, breasts, and upper arms. They are commonly experienced during periods of rapid growth, weight gain or loss, pregnancy, adolescence, or bodybuilding.

Causes

Skin Stretching: The primary cause of stretch marks is the skin stretching beyond its elastic capacity, which can occur during pregnancy, puberty, or rapid weight fluctuations.
Collagen and Elastin Breakdown: The stretching leads to the breakdown of collagen and elastin, proteins responsible for the skin’s elasticity and structure.
Genetic Factors: A family history of stretch marks can increase the likelihood of developing them.
Hormonal Changes: Hormonal fluctuations during pregnancy, adolescence, or certain medical conditions can contribute to the formation of stretch marks.
Medical Conditions: Certain medical conditions or medications, such as corticosteroids, can weaken the skin’s elasticity and make it more prone to stretch marks.
