Stretch marks, medically known as striae, are lines or streaks that form on the skin when it is stretched too quickly. They often appear due to rapid growth or weight changes, commonly during puberty or pregnancy. Stretch marks vary in color and texture and may fade over time. Many people seek treatment to improve skin smoothness and appearance of stretch marks. Although they pose no health risks, stretch marks can affect self-confidence, especially when they appear in visible areas like the abdomen, thighs, or arms.
