Striae
Striae is also a general term referring to thin, narrow grooves or channels, or a thin line or band especially if several of them are parallel or close together.
Stretch marks or striae ( singular stria) as they are called in dermatology are a form of scarring on the skin with an off color hue.They are caused by tearing of the dermis and over time can diminish but not disappear completely.
Striae often the result of the rapid stretching of the skin associated with rapid growth (common in puberty) pr weight gain ( e.g pregnancy,muscle building, or rapid gain of fat) or in some cases,severe pulling force on skin that overcomes the dermis's elasticity. Stretch marks may also be influenced by hormonal changes associated with puberty, pregnancy, muscle building,hormone replacement therapy for transsexual,etc.
STRETCH MARKS ARE DAMAGED ELASTIN
These
elastin fibers are damaged in stretch marks, causing the 'scar' of a
stretch mark. What's so remarkable about stretch marks is how prominent
they look, but under a microscope you see almost no difference from
normal, healthy skin. If you touch a stretch mark, it feels empty,
almost like there is no skin there. Visually and textually the skin is
so very different, yet so little has actually changed in the skin.
