What is Rejuran and How Does It Improve Scarring?

Rejuran is an injectable treatment known for its regenerative properties, particularly effective in treating acne scars. It contains polynucleotides (PN) derived from salmon DNA, which stimulate collagen production and enhance skin healing.
How Rejuran Works
  • Polynucleotides: These DNA fragments are injected into the dermis, where they stimulate fibroblasts to produce collagen. This process helps fill in acne scars and improve skin texture by regenerating skin tissues​​. 
  • Anti-Inflammatory Properties: Rejuran also reduces inflammation, promoting faster wound healing and reducing redness and swelling​.
  • Injections: Administered via a series of microinjections into the targeted areas. The treatment is generally well-tolerated, with numbing cream applied beforehand to minimize discomfort. 
  • Areas Treated: Commonly used on the face, including cheeks, forehead, around the eyes, and on the neck. It is particularly effective for acne scars and can also treat wrinkles and large pores​​.

  • Frequency: Typically, 2 to 4 sessions are needed for optimal results, spaced 3 to 6 weeks apart. Noticeable improvements often appear after the 1st or 2nd session, with maximum results visible 2-3 months after the final treatment​​. 
  • Maintenance: For sustained benefits, maintenance treatments are recommended once or twice a year.

4. COST:
  • Price per Session: Cost ranges from $500 to $1,000 per session. Each session usually involves 2-3 syringes of the product​.

  • Minimal Downtime: Recovery time is typically less than 48 hours, during which minor swelling or redness at the injection sites may occur. These side effects usually resolve quickly, allowing patients to return to their daily activities soon after treatment​.

  • Permanent Results: Unlike temporary fillers, Rejuran provides a more permanent solution by boosting the skin’s natural collagen production and repair mechanisms. Once scars are treated, they are unlikely to revert to their original state​.
  • Safety: Generally safe, with a low risk of allergic reactions. Individuals allergic to salmon should avoid this treatment. Side effects are typically mild and temporary​​.

Rejuran offers a promising solution for those seeking to reduce acne scars and improve overall skin health through natural collagen stimulation and enhanced skin regeneration.
