Stretchmarks vary in colour and size from purple, grey or white and they have a different texture to the rest of the skin.
The common cause of stretch marks is often related to the sudden change of weight such as pregnancy or weight loss/gain and in adolescents (growth).
Stretch marks are not dangerous or harmful but their appearance to some, depending on where they are located, can cause concern especially when there’s a significant difference in colour and or size.
