Detailed answer

While stretch marks can be caused by various factors such as rapid weight gain, pregnancy, or hormonal changes, there is a genetic component to their development. The elasticity and strength of your skin are partly determined by genetics, so if your parents or close relatives have stretch marks, there is a higher chance that you may develop them as well. However, it is important to note that genetics is not the only factor, and lifestyle choices, diet, and skincare routines also play a significant role in minimizing the appearance of stretch marks.
