What Are Stretch Marks?
Stretch marks, also known as striae, are a type of scar that occurs when the skin stretches rapidly. This quick stretching damages the collagen and elastin fibers in the skin, hence their name, “stretch” marks.
The appearance can vary depending on the individual’s skin type and the severity, location, and age of the stretch marks. New ones are often red or purple, while older ones are silvery or white. They can also be indented or raised.
