It isn’t necessary that everyone develops stretch marks on their skin, fluctuating hormone levels seem to play a role. You are at a higher risk if someone in your family has stretch mark issues. And if you develop stretch marks, you’re most likely to do so during these times:
Growth spurts that happen in puberty
Pregnancy
Rapid weight loss or weight gain
Weight training when you have rapid muscle growth
Applying a corticosteroid cream to your skin for a long time can also cause stretch marks.
Medical conditions like cushing’s disease.
