Drink plenty of water. Adequate hydration keeps your skin soft and less likely to develop stretch marks. Caffeine can increase your risk of stretch marks. If you're stuck on your caffeinated coffee or tea, make sure you balance the fluids. Drink just as muchâor moreâwater as you drink coffee, tea, or soda. Stretch marks can also result from nutritional deficiency. Be sure to consume foods that promote skin health: foods rich in zinc, such as nuts or fish; foods high in vitamins A and C, such as carrots and citrus fruits and milk; protein-rich foods, such as eggs.
