Rejuran S (Blue): The Acne Scar Repair Specialist Skin Booster

Acne scars, pitted skin, uneven texture — many assume fractional lasers are the only solution, but they are expensive, have long recovery, and uncertain results. In Korean dermatology, there is a specialized injection protocol for these issues: 【Rejuran S (Blue)】.

Rejuran is known as the “Hermes of skin boosters” in Korea, but most only know Black (full-face repair and anti-aging) and are unclear about Blue. This article breaks down Rejuran S’s positioning, core benefits, and suitable candidates.

What Is Rejuran S — Key Differences from Black and White

Rejuran has four main variants: 【Black (Healer)】, 【White (I)】, 【Blue (S)】, and 【Red (HB)】. The key to choosing is understanding your skin concern.

  • 【Black】 focuses on full-face repair and anti-aging, 2% PN concentration, for early aging, sensitivity, and damaged barrier.
  • 【White】 targets the eye area, for dark circles and under-eye fine lines.
  • 【Red】 focuses on hydration and brightening.
  • 【Blue Rejuran S】 has a completely different positioning — the S stands for 【Scar】, making it a 【localized repair skin booster】. Blue has the 【highest PN concentration and strongest viscoelasticity】 in the series, specifically targeting acne scars, pitted skin, and localized depressions. Unlike regular skin boosters that are evenly injected across the face, Blue is 【injected point-by-point into scar areas】, where the high-viscosity formula remains in place to effectively repair fibrous tissue damage.

Core Ingredients and Benefits

The core ingredient is 【PDRN (polydeoxyribonucleotide)】, extracted from salmon DNA, 98% similar to human DNA. Once in the dermis, it 【stimulates cell regeneration from the root】 and repairs damaged cells. Blue also contains additional 【anti-inflammatory ingredients】 that soothe skin inflammation and reduce new acne formation.

【Five core benefits:】

  • 【Repairing acne scars and pits:】 Promotes skin regeneration, fills in acne scars, and restores smooth skin.
  • 【Lightening acne marks and scars:】 Effectively addresses scar tissue formed by inflammatory fibrous tissue damage.
  • 【Improving acne-prone skin with anti-inflammatory soothing:】 Regulates oil-water balance and reduces new acne formation.
  • 【Activating skin regeneration:】 Stimulates the skin’s natural regenerative ability and maintains normal cell metabolism cycles.
  • 【Firming and hydrating:】 Improves elasticity and texture in scarred areas.

Who Is Rejuran S Suitable For?

【Suitable for:】 Those with 【acne-prone skin, acne scars, pitted skin, and uneven texture】. Dermatologists typically recommend Blue for those whose acne has stabilized (no longer frequently breaking out).

【Not suitable for:】 Blue has the highest concentration in the Rejuran series and requires injection into the 【deep dermis】, demanding higher technical skill from the doctor. For active acne breakouts, it is recommended to control inflammation first before considering Blue for scar treatment.

Pricing Reference

Korean Rejuran S prices vary by clinic:

  • 【NowMedi Hospital:】 Blue 2cc (both cheeks) promotional price 400,000 KRW

【Course recommendation:】 Blue requires 【multiple sessions】 for optimal results. Recommended at 【3 to 4 week intervals】 for 【2 to 4 sessions】 as a complete foundational course. After intensive treatment, maintenance every 6 to 12 months.

Rejuran S vs. Fractional Laser

Many struggle between Blue and fractional lasers for acne scar repair.

  • 【Blue’s advantages:】 Non-invasive, short recovery (2-5 days), no skin breaking, can be layered across multiple sessions.
  • 【Fractional laser:】 Stronger for deep scars, but longer recovery (7-14 days), risk of post-inflammatory hyperpigmentation, and noticeable pain.
Your SituationRecommended Option
Mild to moderate scars, want to avoid laser recovery【Rejuran S】
Deep, stubborn scars, seeking one-time major improvement【Fractional laser】
Moderate scars, want comprehensive skin improvement【Blue + fractional laser combined】

Rejuran S has a clear positioning within the Rejuran line: 【the localized repair specialist for acne scars】. It is not a replacement for Black or an upgrade of White — it is a skin booster designed specifically for “localized depressions.” Black addresses “overall skin quality,” Blue addresses “localized acne scars.” Understanding this distinction tells you whether it is right for you.
