What is a Stretch Mark?
Stretch marks can occur when the skin overstretches due to fast growth such as during pregnancy, adolescence, weight gain and exercise.
They start off as red/purple lines over the area of skin that has been stretched, and eventually fade to silvery white lines.
Stretch marks are extremely common and develop for many different reasons when the skin becomes overstretched, some of which could include:
- Rapid weight gain or loss
- Rapid muscle growth in weight trainers
- Rapid growth in teenagers during puberty
