Stretch marks, also known as striae, are a type of scar that develops when the skin stretches or shrinks quickly. This abrupt change causes the collagen and elastin, which support the skin, to rupture, leading to the appearance of stretch marks. They can appear as narrow bands on the skin and are commonly seen on the abdomen, breasts, hips, buttocks, and thighs. Stretch marks can vary in color, from red, purple, pink, reddish-brown, to dark brown, depending on the individuals skin color. Over time, the color fades, and the narrow bands sink beneath the skin, often leaving a slight depression when touched.
Several factors can contribute to the development of stretch marks, including rapid growth during puberty, pregnancy, rapid weight gain or loss, and the use of corticosteroids. Additionally, fluctuating hormone levels and genetics may also play a role in the likelihood of developing stretch marks. While stretch marks are permanent, various treatments are available to make them less noticeable and alleviate any associated itchiness. However, its important to consult a doctor, especially if pregnant or breastfeeding, before pursuing any treatment for stretch marks.
