Stretch marks, or striae, are streak-like lines that form when the skin stretches or contracts rapidly. This sudden change places stress on the deeper layers, causing tiny tears in collagen and elastin fibers. Marks often begin red, purple, or dark brown (depending on skin tone) and gradually fade to lighter shades over time.
Though harmless, stretch marks are very common and often viewed as a cosmetic concern. They frequently appear on the abdomen, thighs, hips, breasts, or upper arms, and can affect confidence when noticeable in these areas.
They are most often linked to pregnancy, puberty, weight fluctuations, or rapid muscle growth. Genetics, hormonal shifts, and conditions affecting collagen or skin elasticity can also increase susceptibility.
While they can’t always be fully prevented or erased, several treatments help reduce their visibility and improve skin texture. Options include topical therapies, microneedling, laser procedures, and other techniques that stimulate collagen remodeling for smoother skin.
Signs & Symptoms
- Stretch marks typically present as red, purple, or dark streaks. Over time, they fade to lighter or white lines that may look slightly sunken compared to the surrounding skin.
- Commonly seen on the abdomen, breasts, thighs, buttocks, hips, and shoulders—areas that undergo frequent stretching.
- They may cause mild itching or discomfort as they form but are generally symptom-free once matured.
- Stretch marks can fade with time, but do not fully disappear on their own. Early treatment often provides the best results.
Causes & Risk Factors
Stretch marks develop when the skin stretches faster than its elastic support system can adapt. Common causes include:
- Pregnancy
- Adolescence / Growth spurts
- Rapid weight gain or loss
- Bodybuilding or rapid muscle growth
- Genetic predisposition
- Corticosteroid use (long-term)
- Hormonal or medical conditions affecting collagen or elastin production
Treatment Options
While no treatment can completely erase stretch marks, many therapies can significantly reduce their visibility and improve skin texture. Treatment options may include:
- Topical Prescriptions – medical-grade creams to improve texture and tone
- Laser Therapy (ResurFX® / Fractional CO2 / IPL) – stimulates collagen to smooth and fade scars
- Microneedling – enhances collagen production and skin tightening
- Chemical Peels – exfoliates and promotes renewal for smoother skin
