White, Black, Blue, Red – the more Rejuran models there are, the harder it is to choose? The core differences actually lie in PN concentration and functional focus: Black is for full‑face anti‑ageing and repair, White is specialised for periorbital fine lines and dark circles, Blue targets stubborn acne scars, and Red contains lidocaine for those who are pain‑sensitive. In Gangnam, Seoul, a single vial ranges from ₩110,000 to ₩400,000, with effects lasting 6 to 12 months. As for which model suits your skin type and whether they can be combined – the following clearly explains the indications for all four models, helping you find your match.
Rejuran is a premium skin regenerative injectable developed by Korean biopharmaceutical group PharmaResearch. Its core ingredients are PDRN and PN extracted from wild salmon reproductive cells, which share a high similarity with human DNA and offer excellent biocompatibility. PN has a longer molecular chain, forming a stable “scaffold” in the skin to continuously stimulate new collagen production; PDRN has a shorter chain, focusing more on anti‑inflammatory and rapid repair effects. Rejuran is not a regular skin booster – traditional boosters mainly contain hyaluronic acid for surface hydration, whereas Rejuran uses PN/PDRN to penetrate the dermis, repairing damaged tissue at the cellular level and activating fibroblasts for fundamental anti‑ageing and skin quality improvement.
Rejuran is especially suitable for those with:
Absolute contraindications: Active skin infection in the treatment area; pregnancy or breastfeeding; allergy to salmon‑derived ingredients; severe autoimmune disease.
Rejuran has four main injectable models – Black, White, Blue, and Red – along with other products like 3+3 Baby针, Salmon, and White Porcelain针. The key differences among the core four lie in PN concentration, viscosity, and functional focus. Below is a comparison of the mainstream models in Gangnam, Seoul, for 2026:
| Model | Specification | Core Ingredient | Main Effects | Applicable Area | Suitable Candidates | Reference Price (KRW) |
|---|---|---|---|---|---|---|
| Black (Healer) | 2ml × 2 vials | High‑concentration PN (2%) | Full‑face anti‑ageing, deep repair, tightening, pore reduction | Full face, neck | Ageing skin, sensitive redness, compromised barrier | ₩270,000 – 400,000 |
| White (Eye) | 1ml × 1 vial | PN (1%), light texture | Fades dark circles, improves tear troughs, smooths periorbital fine lines | Periorbital area | Dark circles, eye bags, fine lines, tear trough depressions | ₩119,000 – 189,000 |
| Blue (S) | 1ml × 1 vial | High‑concentration PN (highest viscosity) | Repairs acne scars, fills depressed scars | Facial scar areas | Stubborn acne scars, atrophic scarring | ₩180,000 – 280,000 |
| Red (HB) | 1ml × 1 vial | PN (1%) + HA + Lidocaine | Deep hydration + repair + lower pain | Full face, neck | Dry skin, pain‑sensitive, first‑timers | ₩199,000 – 250,000 |
Selection advice: For anti‑ageing and repair choose Black (full‑face comprehensive improvement); for hydration and pain‑sensitivity choose Red (contains lidocaine for comfort); for periorbital concerns choose White (precision care); for acne scars choose Blue (high viscosity filling). For optimal results, you can combine Black + White (full‑face base + periorbital refinement) or Black + Blue (anti‑ageing + scar treatment).
Step 1 – Consultation: The Korean dermatologist evaluates skin type, concerns, and pain tolerance to select the appropriate model and injection plan.
Step 2 – Preparation: Cleanse the treatment area and apply topical anaesthetic cream for about 30‑40 minutes to enhance comfort.
Step 3 – Precise procedure: The doctor administers Rejuran via manual injection or device‑assisted methods, targeting the correct layers. Full‑face treatment takes about 20‑40 minutes. Sensation is a mild pinprick; Red is less painful due to Lidocaine.
Step 4 – Post‑care: Small bumps, redness, and bruising may appear and usually resolve within a few days. Avoid water and makeup for 24 hours; avoid sauna, alcohol, and strenuous exercise for 3‑7 days.
Immediate effect: Skin becomes softer and more radiant within 1‑2 days after treatment.
Progressive effect: Rejuran works through progressive repair – at 2‑4 weeks, skin texture improves noticeably, fine lines soften, pores shrink, and skin tone brightens. A full course of 3 sessions (spaced 3‑4 weeks apart) significantly enhances skin stability and elasticity.
Duration: A single session lasts 1‑2 months; after a full course (3 sessions), results can last 6‑12 months. It is recommended to have maintenance every 3‑6 months for long‑term skin maintenance.
Q1: What is the difference between Rejuran and a skin booster?
A: A skin booster mainly contains hyaluronic acid for surface hydration, lasting 1‑3 months. Rejuran uses PN/PDRN for deep repair and collagen regeneration at the cellular level, lasting 6‑12 months, which is why it is often called the “king of skin boosters.”
Q2: Is Rejuran painful?
A: A topical anaesthetic is applied beforehand; most people experience only a mild pinprick and tolerate it well. If you are particularly pain‑sensitive, choose Red (HB) as it contains Lidocaine for a more comfortable experience.
Q3: Can White and Black be injected together?
A: Yes – this is a golden combination recommended by many Korean dermatology clinics. Black serves as a full‑face anti‑ageing base, while White provides periorbital precision care, resulting in a more refined and natural overall outcome.
Q4: How much does Rejuran cost in Korea?
A: In 2026 Gangnam, Black ~₩270,000‑400,000 (2ml×2); White ~₩119,000‑189,000 (1ml); Red ~₩199,000‑250,000 (1ml); Blue ~₩180,000‑280,000 (1ml). Prices vary by clinic, doctor, and promotions; package deals are usually more cost‑effective.
Q5: How many sessions are needed to see noticeable results?
A: Rejuran is a progressive maintenance treatment. A full course of 3 consecutive sessions (spaced 3‑4 weeks apart) is recommended. Significant skin improvement begins to appear 2‑4 weeks after the first session.
Common side effects: Small bumps, redness, and bruising may occur and usually resolve within a few days. In very rare cases, infection or allergic reaction may happen.
Rational advice: Rejuran is a prescription‑grade aesthetic product that must be administered by a qualified physician at a licensed clinic. When choosing a clinic in Korea, confirm the product is genuine – use HiddenTag scanning or NFC verification. Discuss your expectations clearly with the doctor – Rejuran delivers progressive and natural skin improvement, not a “one‑time face change.” Beauty is worth investing in, but Safety always comes first.
