What are pregnancy stretch marks? We know this question is on a lot of our expecting mama’s minds. Read on to discover what stretch marks are, why they develop during pregnancy, and how our bodycare can help to improve their appearance.

What Are Stretch Marks Caused By?

You may notice that stretch marks (…or mama marks as we like to call them) have appeared on your stomach, breasts, buttocks or thighs during your 9-month str-e-tch. But why? Well, during pregnancy, the skin rapidly expands to accommodate a growing baby bump. As the name suggests, these marks are a result of this stretched skin, and its effect on the skin's underlying collagen structure.

Collagen is a major (and naturally-occurring) component of our skin. Within the deeper layers of the skin, collagen is arranged into tight bundles called fibres. Its main role is to provide structure and support. In other words, it helps to keep our skin feeling firm and plump. The stretching experienced during pregnancy can cause tension within the skin, which can ‘pull apart’ and damage these collagen bundles, resulting in stretch marks. When this happens, our skin attempts to repair these ‘tear-like’ ruptures by producing more collagen. However, as our skin quickly adapts to repair this damage, the collagen produced is believed to be thinner and less organised than ‘regular’ collagen fibres. These changes within the skin’s collagen structure, is what leads to the visible difference between a stretch mark and the surrounding skin.

What Colour Are Stretchmarks?

The colour and texture of a stretch mark will change over time. When a new mark appears, it is often raised or ‘bumpy’ and will have a pink, or ever purple hue. This is due to the colour of the underlying blood vessels, which become more visible as the skin stretches. As time passes, it will become thinner and fade to a white or silvery colour, with a ‘wrinkled’ appearance. This is due to the physical changes in the structure of underlying collagen. Stretch marks may also appear glossy or shiny in comparison with the surrounding skin.

What Can You Do To Help Improve Their Appearance?

Interestingly, stretch marks are believed to behave similarly to ‘scars’. This is due to the similarities in their formation and characteristics. Areas of the skin which are scarred (like stretch marks) are known to have a weakened barrier function. The skins barrier function is crucial for retaining water and keeping our skin hydrated. When our skins barrier is not functioning as effectively, it is much more prone to water loss. This can lead to dryness and may leave the skin feeling less elastic (which can further exaggerate the appearance of stretch marks). It is believed that improving the skins barrier function, can help to improve the appearance of stretch marks. As hydrating the skin is an effective way of improving our skins barrier function, using moisturising body-care products (such as oils, creams and butters) can be super beneficial.

Our Mama Marks Cream also contains the super-hydrator know as Sodium Lactate. Sodium Lactate is actually a naturally-occurring component of the skin, which attracts and binds water from the atmosphere (which helps to protect against moisture-loss). This helps to leave the skin feeling uber-hydrated and more elastic! What’s more, is that 83% of mamas agreed that the appearance of stretch marks were transformed. *

As a Cosmetic Scientist (and self-proclaimed skincare junkie) I’m always searching for new arrivals on the beauty scene. I love to explore new innovative ingredients, and how they work on the skin to achieve the visible results we all want. My morning must-have is a high-potency Vitamin C serum, followed by a Retinol cream in the PM.
