Stretch Marks and Jeans: What's the Connection?

Tight jeans do not directly cause stretch marks.

Stretch marks result from the overstretching of the skin, usually during rapid weight gain or muscle growth. Tight jeans may contribute to the appearance of stretch marks if they put excessive pressure on certain areas of the skin, particularly if the skin is already stretched or weakened. Rapid weight fluctuations, sudden growth spurts, pregnancy, and genetic factors are more significant contributors to stretch marks.
