Overview
Stretch marks, also known as striae, are a type of dermal scarring that develops when the skin is stretched or contracted more quickly than it can adapt.
This rapid change places stress on the skin’s collagen and elastin fibres, leading to small tears within the deeper layers of the skin. As the skin heals, stretch marks form as visible lines or streaks.
They often begin as red, purple or darker lines and gradually fade over time to a lighter, silvery appearance.
Stretch marks are extremely common and not harmful, but they can be persistent and may not disappear completely, even with treatment.
How we approach stretch marks
At Mirabel, stretch marks are approached with a focus on improving skin quality and supporting repair within the deeper layers of the skin.
The aim is to:
• Stimulate collagen to improve skin texture and strength
• Soften the appearance of stretch marks over time
• Improve overall skin tone and smoothness
• Support the skin’s natural repair processes
Because stretch marks are a form of scarring, treatment focuses on improvement rather than removal.
A considered, staged approach allows for gradual, visible change while maintaining realistic expectations.

What you may notice
Stretch marks typically present as:
• Linear lines or streaks on the skin
• Red, purple, pink or darker marks in earlier stages
• Pale, silvery or white lines over time
• Skin that may feel slightly indented or textured
• Common areas such as the abdomen, thighs, hips, breasts or buttocks
They may appear suddenly during periods of rapid change and gradually soften in appearance.
What is happening in the skin
Stretch marks develop when the skin’s structural fibres are disrupted.
This can involve:
• Rapid stretching or shrinking of the skin
• Breakdown of collagen and elastin fibres
• Small tears within the deeper layers of the skin
• Healing that results in visible linear scarring
Because the damage occurs within the dermis, stretch marks behave differently from surface-level concerns and require a deeper, structural approach.
What can influence stretch marks
Stretch marks are often linked to periods of rapid change in the body:
• Pregnancy
• Growth spurts during puberty
• Weight gain or weight loss
• Muscle growth or body composition changes
• Hormonal influences or certain medications
Genetics also plays a significant role in how likely someone is to develop stretch marks and how they appear.
When to seek advice
If you are concerned about the appearance of stretch marks, a more tailored approach can help to clarify what is possible and what may be most effective.
Seeking advice can help to:
• Understand the stage and type of stretch marks
• Identify appropriate treatment options
• Improve skin texture and appearance over time
• Set realistic expectations for improvement
