Quick Answer
Rejuran S is PharmaResearch's scar-treatment-specific polynucleotide — the Blue Box of the Rejuran family. It uses a higher-concentration PN formulation than Rejuran Healer, designed specifically for depressed atrophic scars including acne scarring, surgical scars, and early-stage stretch marks. Standard course is 3–5 sessions 3–4 weeks apart with focal subcision-style injection under each scar.
Why This Skinbooster Is Different
Rejuran S is the only product in the Rejuran range with KFDA approval specifically for scar treatment. The higher PN concentration drives more aggressive fibroblast activation and collagen synthesis in the scar bed — necessary because scar tissue has reduced cellular density and impaired regenerative response compared to normal dermis. Subcision-style focal bolus technique creates volume directly under the depression while triggering remodelling.
Mechanism of Action
High-Concentration PN for Depressed Scar Tissue Reconstruction. PN at scar-grade concentration is delivered via focal subcision-style injection directly beneath atrophic scar depressions. The needle insertion mechanically releases fibrous tethers binding the scar base; the deposited PN then triggers concentrated fibroblast activation in tissue that normally has impaired regenerative response. Over weeks, new collagen synthesis rebuilds dermal volume within the scar bed, gradually reducing visible depth.
Frequently Asked Questions
What is Rejuran S 1.0ml?
Rejuran S is the scar-treatment-specific product in the Rejuran polynucleotide range — packaged in the Blue Box. The S stands for Scar. It contains a higher PN concentration than Rejuran Healer, formulated for atrophic depressed scars including acne scars, post-surgical scars, and early stretch marks.
How is Rejuran S different from Rejuran Healer?
Rejuran Healer (Black Box) is the classic anti-aging formulation at 2% PN for general skin regeneration. Rejuran S (Blue Box) uses a higher PN concentration designed for the deeper tissue reconstruction needs of atrophic scarring. The injection technique also differs — S uses focal subcision-style bolus under each scar; Healer uses superficial dermal micro-droplets across the field.
What types of scars can Rejuran S treat?
Atrophic (depressed) scars are the primary indication. This includes acne scars (icepick, rolling, boxcar morphologies), post-surgical depressed scars, post-traumatic scars with depth loss, and early-stage stretch marks where collagen architecture is recoverable. Hypertrophic and keloid scars are not appropriate targets — different mechanism required.
How does Rejuran S work on scars?
Atrophic scars have reduced collagen content and disorganised matrix architecture beneath the depression. Rejuran S delivers high-concentration PN directly into the scar bed via subcision-style injection. PN binds fibroblast A2A receptors, triggering proliferation and new collagen synthesis. Over weeks, the new collagen rebuilds dermal volume, reducing visible scar depth. The needle subcision itself also breaks fibrous tethers.
How many sessions are needed for scar treatment?
3 to 5 sessions, spaced 3 to 4 weeks apart. Severe or long-standing scars may need more sessions. Visible improvement appears after session 2 to 3 and accumulates. Many practitioners combine Rejuran S with adjunctive treatments — fractional laser, microneedling RF, or TCA CROSS — for synergistic outcomes.
Can Rejuran S be combined with other scar treatments?
Yes — combination protocols are common. Typical combinations: Rejuran S + fractional CO2 or Er:YAG laser (laser creates damage, PN drives regeneration); Rejuran S + microneedling RF; Rejuran S + TCA CROSS for icepick scars. Spacing of 1 to 2 weeks between modalities is standard.
Is Rejuran S effective for stretch marks?
Yes — early-stage stretch marks (striae rubrae, red-purple, less than 6–12 months old) respond best because the collagen architecture is still recoverable. Mature white striae (striae albae) respond less well; combination with fractional laser improves outcomes. The PN mechanism rebuilds dermal collagen in the striae.
What needle and technique are used?
Insulin syringe or 30G needle for focal subcision-style placement directly under each depressed scar. The needle is inserted at the scar margin, advanced through to the scar base, and PN is injected as a bolus or fanned across the subscar plane. Volume per scar is typically 0.05–0.1 mL.
Is Rejuran S painful?
More uncomfortable than Rejuran Healer because of the focal bolus technique and the higher PN concentration. Topical anaesthetic (lidocaine/prilocaine cream) applied 30 minutes before treatment helps. Some practitioners pre-mix Rejuran S with a small amount of lidocaine for procedural comfort.
How much does Rejuran S 1.0ml cost?
Rejuran S 1.0ml is priced at USD $88.00 per syringe on Fillersfairy, with wholesale pricing for licensed practitioners.

As a clinic owner, this is my second time buying Rejuran S from fillersfairy. Their prices are very attractive to me and it is hard to find genuine Rejuran S at such a big discount these days ,on average one box can save me $6.Rejuran S serum is a great way to meet the needs of customers for skin rejuvenation. My clients love the skin rejuvenation effects of Rejuran S. After completing the standard three-course treatment, problems such as scarring have been significantly improved are very satisfied with the changes in their skin.
