Überdehnungsrisse

Überdehnungsrisse, also known as striae or stretch marks, are a common dermatological condition characterized by the appearance of lines on the skin. These marks develop when the dermis, the middle layer of skin, is stretched or shrunk rapidly. This sudden change causes the collagen and elastin fibers within the dermis to rupture. As the skin heals, these scars appear.

The most frequent causes of Überdehnungsrisse include rapid weight gain or loss, pregnancy (particularly during the third trimester), and periods of rapid growth, such as during puberty. Certain hormonal changes, like those associated with Cushing's syndrome or prolonged use of corticosteroids, can also contribute to their formation by weakening the skin's elasticity. Genetics plays a role, as some individuals are more predisposed to developing stretch marks than others.

Initially, Überdehnungsrisse often appear reddish-purple or dark brown, depending on skin tone. Over time, they tend to fade to a lighter, silvery or white color, becoming less noticeable. While they are generally harmless, some individuals may find them cosmetically undesirable.

Various treatments exist to reduce the appearance of Überdehnungsrisse, though complete removal is often not possible. These treatments can include topical creams containing retinoids or hyaluronic acid, microdermabrasion, laser therapy, and chemical peels. The effectiveness of these treatments can vary greatly depending on the age and appearance of the stretch marks. Prevention strategies often focus on maintaining a healthy weight, moisturizing the skin regularly, and staying hydrated.
