Detailed answer

Stretch marks, also known as striae, are primarily caused by rapid growth or changes in the body's shape or size. They are usually associated with pregnancy, puberty, weight gain, or muscle growth. Stress alone does not directly cause stretch marks, although it may indirectly contribute to weight fluctuations or hormonal imbalances that can lead to their formation. It is important to note that everyone's skin is different, and some individuals may be more prone to developing stretch marks than others. Proper moisturization, maintaining a healthy weight, and managing stress levels can help reduce the likelihood of developing stretch marks.
