Stretchmarks

Stretch marks, or striae, are caused by the rapid stretching of the skin, which results in the breakdown of collagen and elastin fibers. This can occur due to growth spurts during puberty, pregnancy, significant weight gain or loss, or muscle growth from weight training. When the skin stretches too quickly, it loses its elasticity, leading to the appearance of these marks.

Stretch marks appear as streaks or lines on the skin, typically in areas prone to rapid stretching, such as the abdomen, thighs, hips, breasts, and arms. They often start as red, purple, or pink streaks and may feel slightly raised or itchy. Over time, they fade to a lighter, silvery color and become less noticeable, although they typically don’t disappear completely.
