Our skin produces these forms of scarring when stretched too quickly often where fat is stored. They start off with a reddish purple-ish line and over time fade to a silvery white.

The rapid stretching causes the middle layer of dermis to tear, resulting in broken fibres. The tears allow the blood vessels to show through (the redness) although when the blood vessels eventually get smaller, the pale-coloured fatty tissue becomes visible which gives the silvery colour. They may be a confidence drain but help can be given to reduce the visual impact with dermal rolling/micro-needling or radio frequency.
