Polynucleotide S Acne Scar
What is Rejuran S?
What is Polynucleotide (PN) S?
Polynucleotide (PN) S is a groundbreaking skin treatment in the Rejuran Skin Care family that harnesses the regenerative properties of polynucleotides extracted from salmon DNA.
It is specifically designed to address and reduce the appearance of acne scars and other types of superficial scarring, promoting a more even skin texture and improved skin quality.


Benefits of Rejuran S
What is Polynucleotide (PN) S?
✅ Scar Reduction: Targets acne scars, surgical scars, and other textural irregularities in the skin.
✅ Enhanced Skin Texture: Improves overall skin smoothness and reduces pore size.
✅ Increased Elasticity: Boosts collagen production, leading to firmer and more youthful skin.
✅ Hydration and Radiance: Enhances the skin’s natural hydration and leaves it looking radiant and healthy
What are Acne Scars?
Acne scars are a common skin condition that can result from the healing process of acne.
These scars occur when deep, inflamed acne lesions damage the skin and the tissue beneath it. After the acne clears, the body tries to repair the damage.
How Polynucleotide S Helps with Acne Scars
Polynucleotide S is particularly effective for treating atrophic acne scars, which are indentations left behind after an acne breakout.
These scars result when the skin doesn’t produce enough fibrous tissue during the healing process.
The acne scar removal treatment is best suited for the following types of atrophic scars:
- Boxcar Scars: These are broad depressions with sharp edges. They are typically round or oval in shape and give the skin a pitted appearance. PDRN can help by stimulating collagen production, thereby elevating the base of the scar to the level of the surrounding skin.
- Rolling Scars: Characterised by their wave-like appearance, rolling scars are wide and shallow. They are caused by fibrous bands of tissue that develop between the skin and the subcutaneous tissue below. The collagen-inducing effect of PDRN helps break up these bands and fill in the depressions.
- Ice Pick Scars: These are deep and narrow scars that extend into the dermis. While PDRN can provide some improvement, these scars are often more challenging to treat and might require combination therapies for significant improvement.
Salmon DNA injection works by delivering polynucleotide-rich content that promotes cellular growth and collagen synthesis.
This not only helps fill up the scars but also improves the overall texture and elasticity of the skin.
Multiple treatment sessions are typically needed for optimal results, with the improvements becoming more apparent gradually over time as the skin heals and regenerates.
Where Can Polynucleotide S Be Injected?
Polynucleotide S is primarily used for facial treatments, especially targeted at areas with acne scars.
However, it can also be injected into other parts of the body where scars and skin repair are needed.
The precise application ensures that the benefits are maximized in targeted areas needing regeneration and healing
Side Effects of Polynucleotide S
Polynucleotide S treatments are generally well-tolerated. Common side effects include:
- Redness and Swelling: Short-term redness or swelling at the injection sites.
- Bruising: Some patients may experience bruising, which typically resolves within a few days.
- Minor Pain: Temporary discomfort during and shortly after the procedure, often mitigated by topical anaesthetics.
These side effects are usually mild and subside within a few days post-treatment
Polynucleotide S Treatment Process
The treatment involves precise microinjections that target affected areas to maximise the healing effect.
Typically administered in a clinic setting by a trained aesthetic doctor, the procedure is quick, with each session lasting about 30 minutes.
While some patients may experience slight discomfort, topical anaesthetics are generally used to reduce pain during the injections.
Polynucleotide S Post-Treatment
Following treatment, patients may notice slight redness or swelling, which usually subsides within a few days.
It is recommended to avoid makeup and adhere to a gentle skincare routine post-treatment to maximise results.
While initial improvements can be seen shortly after treatment, the best results are typically observed after a series of sessions, with recommendations often including three to four treatments spaced one month apart.
