Yes, stretch marks are normal for a 15 year old, especially during periods of rapid growth.
It's common for stretch marks to appear during the teen years due to rapid growth or weight gain. According to research, several factors can make teens more likely to develop stretch marks:
- Rapid Growth or Weight Gain: This is a primary cause during adolescence.
- Genetic Predisposition: A family history of stretch marks increases the likelihood.
- Pregnancy: Although less common at 15, pregnancy can cause stretch marks.
- Being Overweight or Obese: Higher body weight contributes to skin stretching.
- Use of Steroids: Topical or oral steroids like prednisone can weaken the skin and make it more prone to stretch marks.
Therefore, while not every 15-year-old will have stretch marks, their presence is considered normal due to these contributing factors.
