REJURAN S

Rejuran S is a novel injectable treatment specifically designed for addressing superficial acne scars. Introduced in Australia in 2023, it contains polynucleotides derived from salmon DNA. These DNA fragments are injected into the deeper layers of scar tissue to stimulate the body’s natural collagen production, which helps to fill in and smooth out the appearance of acne scars.

How Does Rejuran S Work?

The mechanism of action for Rejuran S involves the injection of polynucleotides into the affected areas. Once injected, these compounds degrade over time and activate fibroblasts—cells responsible for collagen synthesis. This process leads to an increase in collagen production, which is crucial since acne scars often result from insufficient collagen formation during the healing process. By enhancing collagen levels, Rejuran S effectively improves skin texture and reduces the visibility of scars.

Treatment Procedure

The procedure typically takes less than five minutes and can be performed by a nurse or dermatologist. Prior to treatment, a numbing cream or local anesthetic is applied to minimize discomfort. After injections, patients may experience small bumps at the injection sites, which usually resolve within a few days. Recovery time is minimal; most individuals can return to their normal activities immediately or within 36 hours.

Sessions Required

For optimal results, patients generally require 2-4 sessions depending on the severity and extent of their scarring. While some may notice improvements after just one or two sessions, best results are typically observed 2-3 months following the final treatment session.

Longevity of Results

One of the significant advantages of Rejuran S over traditional dermal fillers is that its effects are permanent. Unlike fillers that merely provide temporary volume by filling gaps in the skin (which last from 1-4 years), Rejuran S promotes natural collagen regeneration, making it unlikely for treated scars to revert back to their original state once corrected.

Types of Scars Treated

Rejuran S is particularly effective for superficial low-volume atrophic scars such as boxcar and shallow rolling scars. However, it may not be suitable for deeper scar types like ice pick scars or deep rolling scars, which often require different treatment modalities such as subcision or laser therapy.

Potential Side Effects

Rejuran S has a favorable safety profile with minimal adverse reactions reported. Common side effects include slight bruising or swelling at injection sites; however, serious complications like allergic reactions or nodules have not been documented as of 2023.
