What do red stretch marks on your sholders mean?

Red stretch marks on your shoulders typically indicate rapid changes in skin elasticity, often due to factors like weight gain, muscle growth, or hormonal changes. They occur when the skin is stretched quickly, causing the collagen and elastin fibers to tear. Initially, these marks appear red or purple due to the increased blood flow to the area, but they may fade to a lighter color over time. If concerned, consulting a dermatologist can provide personalized advice and treatment options.
