What Is Stretch Marks?
Stretch marks medically known as striae distensae are narrow, band-like indentations that form in the skin when the dermis is stretched beyond its elastic capacity. They typically begin as red, purple, or dark-toned streaks (striae rubrae) and gradually fade to silvery-white or pale lines (striae albae) over time. Common locations include the abdomen, breasts, hips, thighs, buttocks, and upper arms. While stretch marks are entirely harmless, they are a frequent source of self-consciousness, and professional treatments can significantly improve their colour, texture, and overall visibility.
Professional Stretch Mark Care You Can Trust
At Skin Blossom Pro, our certified aestheticians have extensive experience treating stretch marks at every stage from fresh, coloured marks to older, white scars that have been present for years. Our North Vancouver clinic uses collagen-stimulating technologies and precision resurfacing techniques to rebuild the damaged dermal structure within stretch marks, restoring thickness, pigmentation, and texture. We know that stretch mark treatment requires patience and consistency, so we design progressive treatment plans with realistic expectations and measurable milestones built in from the start.
Who Gets Stretch Marks?
Stretch marks are extremely common, with research estimating they affect up to 80% of the general population at some point:
- Pregnant women Rapid abdominal expansion during pregnancy is one of the most common triggers, with stretch marks developing on the belly, breasts, and hips during the second and third trimesters.
- Teenagers going through growth spurts Rapid vertical growth during puberty can outpace the skin’s ability to stretch, producing stretch marks on the back, thighs, hips, and knees.
- Individuals who gain or lose weight quickly Sudden body composition changes whether from weight gain, rapid muscle building, or significant weight loss stress the skin’s elastic fibres beyond their capacity.
- People using corticosteroid medications Long-term topical or oral corticosteroid use thins the skin and reduces collagen production, making stretch mark formation far more likely.
- Those with a genetic predisposition Skin elasticity, collagen quality, and stretch mark susceptibility are all influenced by genetics, meaning some people are inherently more prone than others.
If your stretch marks bother you cosmetically and you want to explore what professional treatments can achieve, our team is here to help.
Common Causes of Stretch Marks
Stretch marks form when the dermis is stretched faster than it can regenerate, causing structural tearing at the collagen and elastin level:
- Rapid skin stretching Whether from pregnancy, growth spurts, or weight changes, any period of fast physical expansion can overwhelm the dermis's capacity to maintain its structural integrity.
- Hormonal fluctuations Elevated cortisol levels from stress, pregnancy, puberty, or medication weaken elastic fibres in the skin, reducing their ability to withstand stretching forces.
- Corticosteroid use Both topical and systemic corticosteroids directly suppress collagen synthesis in the dermis, making the skin thinner, more fragile, and highly susceptible to stretch mark formation.
- Genetic factors Inherited variations in collagen composition, elastin quality, and skin thickness determine how resistant your skin is to stretch mark development under mechanical stress.
- Reduced collagen and elastin production Age-related or condition-related decreases in structural protein production make the dermis less resilient and more prone to permanent tearing when stretched.
- Underlying medical conditions Conditions like Cushing's syndrome, Marfan syndrome, and Ehlers-Danlos syndrome directly affect connective tissue integrity and are associated with increased stretch mark formation.
Types of Stretch Marks We Treat
Stretch marks progress through distinct stages, and treatment effectiveness depends on identifying where your marks fall on this spectrum:
- Striae rubrae (new stretch marks) Fresh stretch marks that appear red, pink, purple, or dark brown. The colour indicates active inflammation and ongoing dermal disruption, and this stage is the most responsive to treatment.
- Striae albae (mature stretch marks) Older stretch marks that have faded to white, silver, or pale skin-toned lines. The inflammation has resolved, but the dermal scarring and textural depression remain.
- Striae gravidarum Stretch marks specifically associated with pregnancy, most commonly found on the abdomen, breasts, and flanks.
- Striae atrophicans Thin, tissue-paper-like stretch marks associated with long-term corticosteroid use or adrenal conditions, where significant dermal atrophy has occurred.
- Deep or wide stretch marks More pronounced marks with noticeable depth and width, often requiring more intensive and sustained treatment protocols to achieve visible improvement.
Advanced Stretch Mark Treatments at Skin Blossom Pro
Our North Vancouver clinic provides powerful collagen-rebuilding treatments specifically designed to improve the appearance of stretch marks at every stage:
- Microneedling Controlled micro-injuries delivered across the stretch mark surface trigger a concentrated wound-healing response, producing new collagen and elastin that fills in atrophic scar tissue and improves skin texture dramatically.
- RF Microneedling Combining radiofrequency energy with microneedling delivers thermal stimulation deep into the damaged dermis, accelerating collagen remodeling, tightening stretched skin, and restoring structural density within the mark.
- Chemical Peels Targeted chemical exfoliation promotes rapid cell turnover across stretch-marked skin, helping to blend the texture and tone of marks with surrounding healthy tissue.
- LED Light Therapy Red and near-infrared light stimulate fibroblast activity and collagen synthesis within the dermis, supporting the body’s natural repair processes and enhancing recovery between more intensive treatments.
