Detailed answer

Stretch marks, also known as striae, are a common cosmetic concern and do not pose any direct health risks. They occur due to the stretching and tearing of the deeper layers of the skin. While they may cause itching or discomfort in some individuals, they are generally harmless and do not require medical treatment. However, it's essential to consult a healthcare professional if you observe sudden or significant changes in the appearance of your stretch marks, as it could be a sign of an underlying health condition.
