Stretch marks

Stretch marks (striae) are a type of scar that occurs when collagen fibres in the skin are stretched rapidly. Typically occurring in the breast, abdomen and thigh area, stretch marks may first appear as red or purple lines, fading over time to a white or silver colour. They can affect any skin types and conditions.


Our skin is generally very resilient, but there are some life events that cause it to overstretch. This can be due to rapid growth or weight gain, pregnancy, muscle building and puberty.
