Stretch marks on the bum, explained
Stretch marks on the buttocks are scars in the dermis where the skin of the bottom stretched faster than it could adapt. The NHS lists the bottom among the common places for them, and they usually follow puberty, pregnancy, weight gain or training that builds the glutes quickly. Stretch Mark Removal London explains how they change over time and what treatment can do.
New marks on the bum are red, purple or darker than the surrounding skin and fade to pale lines over a year or two. They often appear with marks on the hips and thighs. Most people only see them in a mirror or a photograph, and they are covered by clothing almost all the time, which makes recovery after treatment simple. The guide to reducing the appearance of stretch marks compares the options.
