What do stretch marks look like during pregnancy?
Generally, stretch marks are a type of skin texture change that occurs in pregnant women due to excessive stretching of the skin and hormonal fluctuations during pregnancy. A detailed analysis is as follows:

The color of stretch marks may vary among individuals but typically appears as pink, red, purple, or dark brown. These colors result from visible blood vessels and pigment deposition during the skin's stretching process. Stretch marks usually present as wavy, striped, or irregular patterns, formed by the rupture and reorganization of elastic fibers and collagen fibers in the skin during stretching. They commonly appear on the abdomen, especially around the navel and on both sides of the waist. In addition, the buttocks, thighs, waist, and areas below the waist are also common sites for stretch marks. The appearance of stretch marks is often accompanied by loose, less elastic skin and may cause psychological distress for pregnant women.
During pregnancy, women can use moisturizing creams, olive oil, or other skincare products to keep the skin hydrated, which helps enhance skin elasticity and prevent the formation of stretch marks. Once stretch marks have formed, they are generally difficult to eliminate completely. However, over time and with the skin’s natural healing ability, the color of stretch marks may gradually fade.
