🟢 What it is

Rejuran HB in Korea is a specialized version of the Rejuran family, combining Polynucleotides (PN) with Hyaluronic Acid (HA). The “HB” stands for Hydro Boost, highlighting its dual function:

• PN (Polynucleotides): Repair, regenerate, and strengthen skin at the cellular level.
• HA (Hyaluronic Acid): Deeply hydrate and plump the skin.

This synergy means Rejuran HB not only repairs damaged or aging skin but also provides instant hydration and elasticity, making it a repair + hydration hybrid skin booster.

In Korea, it’s especially popular for patients who want the healing benefits of Rejuran PN plus the hydrating glow of HA boosters—all in one treatment.

🟢 Why it’s Done

Rejuran HB is chosen in Korea for its multi-dimensional benefits:

➡️ Skin repair & regeneration: PN improves cellular repair, collagen, and elastin.
➡️ Hydration & glow: HA adds immediate plumpness and deep moisture.
➡️ Anti-aging effect: Reduces fine lines and strengthens thinning skin.
➡️ Improved elasticity: Boosts skin firmness and resilience.
➡️ Balanced rejuvenation: Offers both long-term repair (PN) and short-term glow (HA).

This makes Rejuran HB ideal for patients who want visible results quickly while also investing in long-term skin health.

🟢 Alternatives

Rejuran HB offers a unique balance, but other options may be considered:

🔹 Rejuran Healer (PN): Stronger focus on repair, less on hydration.
🔹 Profhilo: HA-based bioremodeling, great for hydration + firmness but not regenerative like PN.
🔹 Skinvive / HA Skin Boosters: Provide hydration and glow, but no repair.
🔹 Exosome Boosters: Promote regeneration and healing, often paired with Rejuran.
🔹 Juvelook / Lenisna: Hybrid biostimulators (HA + PLLA) targeting scars and elasticity.

In Korea, doctors often recommend Rejuran HB for patients with both dryness + weakened skin, while Rejuran PN alone may be suggested for repair-focused cases.

🟢 Preparation

Before Rejuran HB treatment, Korean clinics follow standard skin booster protocols:

➡️ Consultation: Skin analysis for hydration levels, barrier strength, and fine lines.
➡️ Medical history: Patients disclose allergies, autoimmune conditions, or previous injectables.
➡️ Avoid blood thinners: No aspirin, ibuprofen, fish oil, or alcohol for 3–5 days.
➡️ Skin care prep: Avoid peels, retinoids, and strong exfoliants before treatment.
➡️ Expectation setting: Results are both immediate (HA) and gradual (PN).

🟢 How it’s Done

The procedure usually takes 20–30 minutes:

1. Cleansing & sterilization of the skin.
2. Numbing: Topical anesthetic applied.
3. Injection technique:
   • Multiple microinjections in a grid pattern across the face.
   • Ultra-fine needles or injector guns used for precision.
   • Common areas: full face, under-eyes, neck, and décolletage.
4. Soothing care: Cooling masks or LED light therapy applied to reduce redness.

Korean dermatologists may combine Rejuran HB with laser brightening or microneedling for synergistic results.

🟢 Recovery

Recovery is minimal, though tiny injection marks are common:

🔹 Downtime: Almost none—daily activities can be resumed immediately.
🔹 Redness/bumps: Small papules at injection sites, usually resolving in 24–48 hours.
🔹 Swelling: Mild, temporary.
🔹 Results:

• Immediate hydration from HA.
• Repair and elasticity improvements from PN after 3–4 weeks.
• Best results after a full course of 3–4 sessions.

✅ Post-care in Korea includes:

• Avoid harsh skincare for several days.
• No saunas, alcohol, or strenuous exercise for 24–48 hours.
• Gentle hydration creams and daily SPF protection.

🟢 Complications

Rejuran HB is safe, but as with any injection, mild issues may appear:

⚠️ Mild effects:

• Redness, tenderness, small bumps.
• Temporary bruising at injection sites.

⚠️ Rare risks:

• Infection if aftercare is neglected.
• Allergic reaction (very rare due to high compatibility).
• Uneven results if not evenly injected (usually corrected in follow-ups).

➡️ Korean dermatologists minimize risks with sterile injector techniques and fine-needle precision.

🟢 Treatment Options in Korea

Rejuran HB is widely used in Korean dermatology clinics for patients who want hydration + repair in one treatment:

🔹 Popular treatment areas:

• Face: Improves elasticity, hydration, and glow.
• Under-eyes: Strengthens thin skin and reduces fine lines.
• Neck & décolletage: Smooths wrinkles and crepey skin.
• Hands: Restores hydration and youthfulness.

🔹 Korean approach:

• Layered therapy: Rejuran HB + Rejuran Healer (PN) for deep repair.
• Combination care: Paired with Profhilo for hydration or Exosome boosters for advanced repair.
• Package sessions: Typically 3–4 sessions spaced a month apart.

🟢 Final Thoughts

Rejuran HB (PN + HA) in Korea is a hybrid skin booster that offers both instant hydration and long-term repair.

➡️ Perfect for patients with dry, aging, or barrier-damaged skin who want both immediate and regenerative benefits.
