Pregnancy brings an incredible transformation of the body, and for many expectant mums, one of the most common skin changes is the appearance of stretch marks. Understanding how and why they pregnancy stretch marks develop before and after, especially in relation to weight gain, hormones, and genetics, can help you care for your skin in a more informed, gentle, and nurturing way.
First, it’s helpful to know what stretch marks are medically known as striae or striae gravidarum when they appear during pregnancy. According to the NHS, they arise when the middle layer of skin (the dermis) becomes stretched and “broken in places” as the skin surface expands.
Your skin is made up of three main layers: the outer epidermis, the middle dermis, and the deeper subcutaneous layer. The dermis is rich in collagen and elastin fibers, which give the skin its strength and elasticity.
During pregnancy, the skin over the abdomen, breasts, and thighs often stretches more quickly than the dermis can remodel. When that happens:
· Collagen and elastin essentially get pulled apart or become less organised, leading to microscopic tears in the dermal network.
· New stretch marks (known as striae rubrae) may appear reddish or purplish due to visible blood vessels under thin skin; over time, they fade to lighter, silvery-white lines (called striae albae).
· Hormonal shifts also play a part. During pregnancy, hormones such as estrogen, relaxing, and cortisol alter skin structure. Cortisol can weaken elastic fibers, and estrogen and relaxing may loosen collagen, making the skin more prone to stretching and tearing.
Why do some women get many stretch marks while others get few or none? Genetics is a significant factor. If your mother or sister developed stretch marks, your risk may be higher. Younger mums and those with fair-skinned or less elastic skin may also be more vulnerable.
Of all the factors, weight gain and the speed of that gain are key. The NHS states that women are more likely to develop stretch marks if their weight gain during pregnancy is greater than average. Rapid stretching of the skin over a short period places high mechanical stress on the dermis.
This means that keeping weight gain steady (within the guidance of your midwife) can help reduce the risk of more pronounced marks.
While it’s true that there is no guaranteed way to prevent stretch marks entirely, what you can do is support your skin so that it is as resilient and well-balanced as possible. Here are practical steps, written from a holistic, supportive perspective how to not get stretch marks:
1. Keep skin well hydrated
Hydrated skin is better able to adapt to stretching. Choose a gentle, fragrance-light moisturizer (safe for pregnancy) and apply it especially to the tummy, hips, thighs and breasts.
2. Gentle daily massage
Massaging those key areas helps support circulation and gives you a nurturing ritual during pregnancy. Massaging oils into the skin can enhance the feeling of care and may help support elasticity (though studies show mixed results regarding prevention).
3. Manage weight gain steadily
Working with your midwife to keep weight gain gradual and within recommended limits is wise. This helps reduce the mechanical stress on skin and supports overall pregnancy health.
4. Eat skin-nourishing foods
Support your skin from the inside: aim for foods rich in vitamins C and E, zinc, and plenty of protein. These nutrients support collagen production and skin repair.
5. Use suitable natural oils and creams
While no oil or cream can promise full prevention, using natural oils or well-formulated creams can support skin health, feel comforting, and reinforce your skincare routine. Choose products with ingredients known for their gentle quality and safe profile in pregnancy.
How natural oils support skin elasticity and health
Using oils in pregnancy is both a tactile and nourishing act. When you apply an oil or blend, you’re helping the skin maintain surface hydration, supporting the lipid barrier, and creating a soothing self-care ritual, which also has emotional benefits for a mum-to-be.
For example, Belly Bump contains Sweet Almond Oil, Calendula Oil, Chamomile Extract, and Lavender Pure Essential Oil. Each of these makes a meaningful contribution:
· Sweet Almond Oil is rich in fatty acids and vitamin E, which help support the skin’s lipid barrier and promote a smoother, more supple feel.
· Calendula Oil is known for its calming botanical profile; it comforts stretching skin and supports gentle nourishment.
· Chamomile Extract adds its soothing, skin-friendly properties, helping reduce any tightness or itchiness that often accompanies stretching.
· Lavender Pure Essential Oil brings both a calm, aromatic experience and known skin-supportive benefits, enhancing the feeling of nurture.
Together, when used regularly (for example, morning and evening as your bump grows), this blend can assist in creating the conditions for skin that adapts well and feels supported.
Stretch marks during pregnancy are incredibly common, affecting around eight out of ten mums-to-be according to the NHS. They are a natural consequence of the body changing and growing to accommodate new life. Are stretch marks preventable? While you may not prevent them entirely, you can absolutely support your skin lovingly and proactively :keep it hydrated, nourish it well, manage your wellness, and use safe, nurturing oils and creams. These steps help not just your skin but your sense of well-being as you move through this exciting chapter of motherhood.
