Stretch marks are a form of scarring that occurs when the skin is stretched too quickly or past its limit. It can also occur during pregnancy and puberty. “Normal” stretching of the skin results in beautiful, evenly textured skin (like how scars add character to someone), whereas stretch marks result in thin stripes on the surface of the skin.
Stretch marks appear in a variety of colors, although most are red initially. In time the color pales and may shift towards silvery-white or dark brown, depending on your skin tone.
You can’t stop stretch marks from forming, but you can reduce their appearance by taking the appropriate steps.
