Striasjoner

Striasjoner are common skin markings that appear as lines or streaks. They are most frequently observed in areas where the skin has been stretched significantly over a short period. The most well-known type is striae distensae, often referred to as stretch marks. These typically develop during rapid growth spurts in adolescence, pregnancy, or during significant weight gain or loss. The underlying connective tissue, particularly collagen and elastin fibers, tears when it cannot keep up with the skin's expansion. Initially, striasjoner may appear reddish or purplish, but over time they tend to fade to a lighter, silvery-white color.

Another form of striation is striae atrophicae, which are related to prolonged exposure to corticosteroids, either through topical creams or systemic medication. These can weaken the skin's structure, leading to thinning and the formation of fine, white lines. Rarer causes of striasjoner include certain medical conditions such as Cushing's syndrome, which involves excess cortisol production, or genetic disorders affecting connective tissue. While striasjoner are generally harmless, they can be a source of cosmetic concern for some individuals. Various treatments are available, including topical creams, laser therapy, and microdermabrasion, though their effectiveness can vary.
