Why do some women get stretch marks and others don't?

Stretch marks are a common concern for many women, often appearing as a result of pregnancy, weight fluctuations, or hormonal changes. Understanding why some women get stretch marks and others don't, can help in managing and treating them effectively.

What are stretch marks?

Stretch marks, or striae, are irregular lines or streaks that appear on the skin when it has been stretched beyond its capacity. These marks commonly occur during pregnancy, obesity, or rapid weight changes, presenting as scars that can vary in colour from pink to brown.

The science behind stretch marks

Stretch marks form when the skin's collagen and elastin fibres are stretched and torn due to rapid growth or weight gain. The damage occurs in the dermis, the middle layer of the skin, causing the visible marks on the surface. Over time, these marks can fade but often remain as permanent reminders of the skin's inability to adapt to rapid changes.

Causes and risk factors of stretch marks

Age: Age is a significant factor in the development of stretch marks. As we age, our skin produces less collagen and elastin, reducing its ability to stretch and recover from damage. Young skin can usually handle rapid growth better, but older skin loses its elasticity, making stretch marks more likely.

Weight Gain: Rapid weight gain, whether from fat or muscle, stretches the skin quickly, causing tears in the dermis. This is particularly common during pregnancy, adolescence, or periods of rapid muscle growth in bodybuilders.

The weight gain from pregnancy happens rapidly in a period of just months. As a result, the skin cannot build fast enough to accommodate the growing need. This weight gain causes stretch marks to occur along the belly area where the pregnancy is obvious. 

Hormones: Hormonal changes play a critical role in the formation of stretch marks. High levels of certain hormones, such as cortisol, can weaken the skin's elastic fibres. This is why stretch marks are common during puberty, pregnancy, and hormone therapy.

Genetics: Genetics can predispose individuals to stretch marks. If your parents had stretch marks, you are more likely to develop them too. Genetic factors influence skin elasticity, collagen production, and the overall health of the skin.

When genetics are a factor, that does not mean you can't see improvement in the appearance of stretch marks. On the contrary, it makes them more likely, but there may be some steps you can take to see a reduction in how obvious they are or how often they develop.

How to reduce the appearance of stretch marks

Unfortunately, there is not always a cure for them, but there are a few simple things that can help how visible they are.

Maintaining skin hydration: Keeping the skin well-hydrated is crucial for maintaining its elasticity. Using moisturisers and body oils can help improve skin flexibility and reduce the risk of stretch marks. Products, such as our body oil, which contain natural ingredients such as cocoa butter, shea butter, and hyaluronic acid are particularly effective.

Micro-needling: Micro-needling involves using tiny needles to create micro-injuries in the skin, stimulating collagen and elastin production. This treatment can significantly reduce the appearance of stretch marks by promoting the growth of new, healthy skin cells.

Skin resurfacing treatments: Radio frequency (RF) skin resurfacing uses thermal energy to stimulate collagen production deep within the skin. This non-invasive treatment helps tighten and rejuvenate the skin, reducing the visibility of stretch marks over time. 

FAQ

Can you prevent stretch marks?

While it is not always possible to completely prevent stretch marks, there are several strategies that may help reduce their likelihood.

A diet rich in vitamins and minerals supports skin health. Nutrients like vitamins A, C, and E, zinc, and omega-3 fatty acids help maintain skin elasticity and repair damaged tissues.

Exercise helps maintain a healthy weight and improves circulation, which supports skin health. Strength training and flexibility exercises can enhance skin tone and reduce the likelihood of stretch marks.

Does everyone have stretch marks?

No, not everyone will develop stretch marks. However, people with less elastic skin or those who experience rapid weight gain are more likely to get them. Genetics and skin hydration levels also play a role.

Why do I keep getting more and more stretch marks?

Stretch marks can continue to develop with ongoing weight gain or hormonal changes. Improving skin hydration and maintaining a healthy weight can help reduce their occurrence.

Can stretch marks be completely removed?

Stretch marks can continue to develop with ongoing weight gain or hormonal changes. Improving skin hydration and maintaining a healthy weight can help reduce their occurrence.

Are there any natural remedies for stretch marks?

Yes, natural remedies like aloe vera, coconut oil, and olive oil can help moisturise the skin and reduce the visibility of stretch marks. Consistent use is key for best results. Our body oil is packed full of natural goodies such as lavender, sweet mandarin and pettigrain essential oils, along with almond oil and jojoba oil to softens and hydrate.

How can I prevent stretch marks during pregnancy?

To prevent stretch marks during pregnancy, maintain a healthy diet, stay hydrated, and use moisturising creams and body oils specifically designed for pregnancy. Regular, gentle exercise can also help.

Is it possible to reduce the appearance of old stretch marks?

Yes, treatments like micro-needling, laser therapy, and certain topical treatments can help reduce the appearance of old stretch marks by promoting collagen production and skin renewal.
