Stretch marks are lines that appear on certain parts of the body as a result of an abrupt stretching of the skin, which breaks the collagen and elastin fibers. They are usually located on the abdomen, hips, breasts, thighs, or buttocks.
Dry skin and a poor diet favor their appearance, as well as an excess of hormones. Some studies also indicate that they have a hereditary component.
During pregnancy, it is advisable to hydrate the skin well, drink plenty of water and take care of your diet to prevent stretch marks. Moderate physical exercise and massaging the affected areas can also help.
