What are stretch marks?
Short answer: Stretch marks are lines or streaks that appear on the skin due to rapid stretching or shrinking of the skin.
Detailed answer
Stretch marks, also known as striae, are a type of scarring that occurs when the skin stretches or shrinks quickly. They commonly appear as lines or streaks on the skin and can have a reddish, purple, or silver color. Stretch marks can occur during periods of rapid growth, such as adolescence or pregnancy, as well as due to sudden weight gain or loss. They are caused by the tearing of the dermis, which is the middle layer of the skin, disrupting the normal collagen production. While they are harmless and do not cause any medical problems, stretch marks can sometimes be a cosmetic concern. They often fade over time but may not completely disappear. Various treatment options, such as topical creams, laser therapy, and microdermabrasion, can help improve the appearance of stretch marks.
