Rejuran i in Korea

Rejuran i

Treatment Overview

Rejuran i is a specialized polynucleotide (PN/PNN) skin booster developed specifically for the delicate under-eye area. Made from purified salmon DNA fragments, it is formulated with smaller PN molecules, allowing safe use on thin, fragile skin without heaviness or risk of puffiness.

Unlike hyaluronic acid fillers that volumize, Rejuran i works biologically to repair DNA damage, improve dermal thickness, stimulate collagen, and reduce fine lines and dark circles.

It is part of the PN/PNN booster family (Rejuran Healer, Rejuran S, Rejuran HB, Plinest, Juvelook, Plenhyage XL):

  • Rejuran i: Best for under-eye wrinkles, dark circles, and skin fragility.
  • Other PN/PNN boosters: Target full-face repair, scars, hydration, or deep elasticity.

Purpose & Benefits

  • Under-Eye Repair: Strengthens thin and sensitive skin under the eyes.
  • Wrinkle Softening: Reduces fine lines and crow’s feet.
  • Dark Circle Brightening: Improves blood flow and skin thickness.
  • Elasticity Boost: Restores firmness to sagging under-eye areas.
  • Hydration: Improves dermal moisture for a plump look.
  • Skin Barrier Protection: Helps protect delicate skin from stress and aging.
  • Synergy with Other PN/PNN Boosters: Rejuran i treats eyes, while Healer, HB, or Plinest restore other areas of the face.

Ideal Candidates

Rejuran i in Korea is recommended for:

  • Adults in their 20s–60s with under-eye wrinkles, hollowness, or dark circles.
  • Patients noticing early aging around the eyes.
  • Men and women comparing Rejuran i vs other PN/PNN boosters:
    • Rejuran i: Best for under-eye rejuvenation.
    • Rejuran Healer: Best for overall regeneration.
    • Rejuran HB: Best for hydration + repair.
    • Rejuran S / Juvelook: Best for scar remodeling.
    • Plinest / Plenhyage XL: Best for elasticity in mature skin.
  • Those seeking a non-surgical eye rejuvenation alternative to fillers or surgery.

Possible Risks & Complications

Rejuran i is safe when performed by Korean dermatologists, though temporary side effects may include:

  • Redness or Small Bumps: Common in thin under-eye skin, fade in 24–48 hours.
  • Mild Bruising or Swelling: More visible due to delicate area.
  • Tightness or Tenderness: May last 1–2 days.
  • Rare Risks: Over-injection or unevenness (minimized by experienced doctors).

Surgical Techniques Used

Although non-surgical, Rejuran i requires precise techniques because of the delicate treatment area:

  • Micro-Injections: PN/PNN carefully injected into under-eye dermis.
  • Cannula or Fine Needle: Used to reduce bruising and ensure safety.
  • Targeted Mapping: Focus on tear troughs, crow’s feet, and fine lines.
  • Layered Application: Sometimes paired with Healer, HB, or mild HA fillers for synergy.
  • Multi-Session Protocol: Usually 3–4 sessions spaced 3–4 weeks apart, with maintenance every 6–9 months.

Recovery & Aftercare

  • Immediately: Mild redness, swelling, or bumps around eyes.
  • 1–3 Days: Skin calms; under-eye area looks refreshed.
  • 2–4 Weeks: Wrinkles soften, dark circles improve.
  • Maintenance: Every 6–9 months for lasting results.

Aftercare Tips:

  • Avoid makeup for 24 hours.
  • Use SPF around the eyes.
  • Apply gentle hydrating/repair creams.
  • Avoid alcohol, saunas, and strenuous activity for 1–2 days.

Results & Longevity

  • Immediate: Slight hydration and smoother under-eye skin.
  • Short-Term (2–4 Weeks): Brighter tone, reduced fine lines.
  • Medium-Term (2–3 Months): Stronger dermal layer reduces dark circles and hollowness.
  • Long-Term: Results last 6–9 months, extended with maintenance.
