Stretchmarks are a common skin condition that appear on various parts of the body due to sudden weight gain, rapid growth or during pregnancy. They are characterized by pink, red or purple lines that later turn into whitish or silvery streaks. There are various synonyms for stretchmarks, including striae, linea albicante, and scarring. Other alternatives include tiger stripes, zebra stripes, skin striations, and skin grooves. While stretchmarks are not harmful, they can affect one's self-esteem, especially in summer when one needs to show some skin. However, with the right skincare routine, they can fade away with time.
