Stretch marks are a type of scarring that can occur when the skin is stretched too quickly. They are often associated with pregnancy, but can also be caused by rapid weight gain or loss, or by certain medical conditions. While stretch marks are not harmful, many people find them unsightly and seek ways to avoid them.
One of the best ways to avoid stretch marks is to keep the skin hydrated. This can be done by drinking plenty of water and using a moisturizer regularly. It is also important to eat a healthy diet that includes plenty of fruits and vegetables. These foods contain antioxidants that can help to protect the skin from damage.
