Stretch marks can occur during sudden changes in body size, such as during pregnancy, puberty, or rapid weight gain or loss.
Large and rapid weight changes is one of the causes of the appearance of stretch marks
When gaining weight quickly and significantly, the skin does not have time to grow and develop more tissue surface. This is when the collagen and elastin fibers break down, making way for tears like on an overstretched tissue. The quantity and quality of collagen fibers play a big role, which is why some people are less affected than others.
Hormonal causes
Excess cortisol, the stress hormone, lowers elastin and collagen levels, which leads to the appearance of stretch marks.
Pregnancy is a very risky period to develop these skin tears because the weight gain is important and fast. The belly in particular will be stretched to the maximum, but also the breasts, thighs and hips will gain volume in preparation for breastfeeding.
Things that worsen the quality of the skin and collagen (structural protein of the skin) include the following:
- Tobacco
- Alcohol
- Sun abuse because too much exposure dries out the skin and destroys antioxidants
- Age reduces collagen synthesis
- Lack of protein
- Lack of vitamins and antioxidants
- Hormonal changes
- Chronic stress
- Chemical or toxic products, perfumes, unnatural creams
