Rejuran for Acne Scars: Everything You Need to Know
Key points:
- Rejuran is a biostimulator made from polynucleotides (PN)—these are DNA fragments derived from salmon.
- Rejuran promotes skin regeneration, improves texture, and stimulates collagen production.
- Especially effective in mild to moderate atrophic (indented) scars like boxcar or rolling scars.
- It’s not a filler—it helps remodel skin over time, leading to smoother, more even skin.
- Results are gradual, typically noticeable after 3–4 sessions spaced a month apart.
- It works best when combined with other treatments like microneedling, laser or subcision if your scars are deeper.
If you’re looking for a fast-recovery, long-term solution for acne scars, Rejuran S might just be your answer. Introduced to Australia in 2023 but backed by years of safe use in Asia and Europe, this injectable treatment uses biostimulatory technology to improve the appearance of atrophic acne scars—especially superficial ones. Here’s a breakdown of what to expect.
What is Rejuran S and how does it work?
Rejuran S is an injectable treatment designed to permanently improve superficial acne scars. It contains polynucleotides—DNA fragments derived from salmon—which are injected directly into scar tissue. These molecules stimulate your skin’s fibroblasts to produce collagen, gradually filling in indented scars over time.
Unlike lasers, there’s minimal downtime—most people are back to normal in less than 48 hours.
Who is Rejuran S suitable for?
This treatment is best for people with superficial atrophic acne scars, like:
- Boxcar scars
- Shallow rolling scars
It’s not ideal for deeper scars (like ice pick scars or deep rolling scars), which typically require other methods like subcision, TCA CROSS, or deeper lasers.
B+A after one session. Ideally 2-4 sessions, spaced 4-8 weeks apart. Injection depth is intradermal. Extrusion force is high to augment hydrodissection.
How is it different from dermal fillers?
Dermal fillers act like “putty” to fill in voids beneath scars. They sit deep under the skin and eventually degrade over 1–4 years.
Rejuran, on the other hand, works higher in the skin—in the dermal layer. It stimulates your own collagen over time rather than just temporarily filling space. The result? Permanent improvement, if you’re a good responder.
How many sessions will I need?
Most patients need 2–4 sessions, spaced a few weeks apart. Some see a visible improvement after just 1–2. Peak results usually show 2–3 months after your final session.
Is the treatment painful?
The procedure is well tolerated. We use a combination of numbing cream and local anaesthetic mixed with Rejuran S. The injections take less than 5 minutes, and most people experience only mild discomfort.
Are the results permanent?
Yes. Rejuran doesn’t just fill scars—it regenerates your skin from within. Once collagen has filled the scar, the change is long-lasting. Unlike fillers, it doesn’t need regular maintenance.
Can Rejuran S be combined with other acne scar treatments?
Absolutely. Rejuran is often part of a comprehensive acne scar revision plan. We may combine it with:
We tailor each plan based on scar type, skin condition, and your healing response.
Will it remove all my scars?
Rejuran can improve scars by 70–80%, especially if they’re the right type. However, it won’t remove all scars—particularly deep or fibrotic ones.
Also, because results depend on your body’s collagen production, not everyone responds equally. Some patients generate more collagen than others, which affects the outcome.
Why must my acne be under control before starting?
Even low-grade inflammation from active acne can hinder collagen production. If your skin is inflamed, your body will prioritise healing over regeneration.
For best results, acne must be in remission before beginning Rejuran treatment. If needed, we’ll refer you to a dermatologist to help calm any active breakouts first.

Are there any side effects?
Rejuran has an excellent safety profile. Side effects are rare but can include:
- Mild swelling or bruising (usually resolves within 48 hours)
- Rare cases of pigmentation at the injection site (<0.1%)
Unlike some fillers, there’s no risk of nodules, allergic reactions, or arterial occlusion.
Is Rejuran S covered by Medicare?
Unfortunately, no—cosmetic injectables aren’t covered by Medicare or private health insurance in Australia. Some international policies may include scar treatments, so it’s worth checking.
Final Thoughts
Rejuran S is an exciting step forward in scar revision. If you’re looking for a non-laser, low-downtime treatment for improving acne scars, Rejuran could be worth considering—especially when part of a larger personalised plan.
