Stretch marks are a common skin concern that affects people of all ages and body types. Whether caused by pregnancy, rapid weight changes, or growth spurts, these linear streaks on the skin can feel frustrating to manage. While countless creams and treatments claim to reduce their appearance, one innovative solution has been gaining attention in recent years: **Rejuran**, a skincare treatment originally developed for wound healing and skin rejuvenation.
So, how does Rejuran work for stretch marks? The key lies in its main ingredient: polynucleotides (PN), derived from purified salmon DNA. These molecules are biocompatible, meaning they integrate well with human tissue. When injected into the skin, PN stimulates collagen production, repairs damaged cells, and improves skin elasticity. Over time, this can help smooth the texture of stretch marks and reduce their visibility. A 2015 study published in the *Journal of Cosmetic Dermatology* found that PN-based treatments significantly improved skin hydration and elasticity in participants with stretch marks, with visible results lasting up to six months.
What makes Rejuran stand out from other treatments? For starters, it’s minimally invasive. The procedure involves tiny injections directly into the affected areas, typically done in a dermatologist’s office. Most people describe the discomfort as mild, akin to a slight pinching sensation. Topical numbing cream is usually applied beforehand to minimize any discomfort. After the session, patients might experience temporary redness or swelling, but these side effects typically fade within 24–48 hours.
One of the biggest advantages of Rejuran is its natural approach. Unlike laser therapies that rely on heat to remodel skin, Rejuran works by supporting the skin’s own repair mechanisms. This makes it suitable for sensitive skin types and reduces the risk of scarring or pigmentation changes—a common concern with more aggressive treatments. Dermatologists often recommend a series of sessions (usually 3–4, spaced a month apart) for optimal results. Maintenance treatments every 6–12 months can help prolong the effects.
But does it work for everyone? While Rejuran shows promise, results can vary depending on factors like the age of the stretch marks, skin type, and overall health. Fresh, reddish-purple stretch marks (called striae rubra) tend to respond better than older, white ones (striae alba). This is because newer stretch marks still have some blood flow and cellular activity, making them more receptive to treatment. That said, even older marks may show improvement in texture and depth after multiple sessions.
Safety is another priority. Rejuran has been widely used in South Korea since 2011 and has a strong track record when administered by trained professionals. However, it’s crucial to consult a licensed provider who can assess your skin and customize the treatment plan. Avoid cheap, unregulated clinics—this isn’t the time to cut corners.
If you’re considering Rejuran, here’s what to expect during a typical session:
1. **Consultation**: Your provider will examine your stretch marks and medical history.
2. **Preparation**: The area is cleansed, and numbing cream is applied.
3. **Injection**: Using ultrafine needles, Rejuran is injected into the middle layer of the skin.
4. **Aftercare**: You’ll receive instructions to avoid sun exposure and strenuous exercise for 24 hours.
Pairing Rejuran with other therapies can enhance outcomes. For example, combining it with microneedling or radiofrequency devices may boost collagen stimulation. Moisturizing daily and wearing sunscreen also helps maintain results.
Cost is a common question. Prices vary by location and provider, but a single session typically ranges from $300 to $600. While this might seem steep, many patients view it as a long-term investment in their confidence. As one user shared on fillersfairy.com, “After three sessions, my stretch marks went from being my biggest insecurity to something I barely notice. It’s been worth every penny.”
Of course, Rejuran isn’t a magic eraser. Managing expectations is key—it reduces visibility rather than eliminating stretch marks entirely. For severe cases, a combination approach (like Rejuran plus laser therapy) might be recommended.
The bottom line? Rejuran offers a science-backed, low-downtime option for improving stretch marks. Its ability to heal from within sets it apart from surface-level creams or invasive procedures. If you’re struggling with stretch marks and want a solution that aligns with your skin’s natural biology, this treatment could be worth exploring. Always prioritize consultations with qualified professionals to ensure safety and tailor the approach to your unique needs.
Lastly, remember that stretch marks are a normal part of life for millions of people. While treatments like Rejuran can improve their appearance, embracing your skin’s story is just as important. As the skincare community often says: “Your body is not a problem to be solved.” But if you choose to explore treatments, do it for yourself—not because society tells you to.
