Stretch marks, clinically known as striae distensae, are dermal scars that develop when the skin is stretched rapidly. They commonly appear as parallel lines on areas like the abdomen, thighs, hips, breasts, and upper arms. These marks occur due to disruptions in collagen and elastin fibers within the dermis, the middle layer of the skin. These disruptions are often triggered by significant weight gain or muscle growth over a short period.
Minimizing the appearance of these dermal scars during periods of intense physical activity holds significant value. Maintaining skin elasticity and health can lead to enhanced aesthetic outcomes, and potentially improve overall skin integrity. Historically, various preventative measures, ranging from topical treatments to gradual weight management, have been employed with varying degrees of success.
