Needle-Free vs Injected Rejuran

Which Treatment Is Better for Glow, Texture, and Anti-Aging?

Rejuran is one of Korea’s most famous skin boosters, known for improving texture, hydration, elasticity, and overall skin health using polynucleotides (PN).

Today, you can choose between two versions:

1. Needle-Free Rejuran (no injection, minimal downtime)

2. Injected Rejuran (classic Rejuran Healer with “bumpy dots”)

Both improve skin — but they work differently, feel different, and deliver different levels of results.

Below is the full, SEO-friendly breakdown to help you understand which one is right for your skin.

What Is Injected Rejuran?

Injected Rejuran uses micro-needles to deliver PN deep into the dermis.
This is the original, full-strength Rejuran known for:

  • Healing damaged skin
  • Smoothing acne scars
  • Improving elasticity
  • Increasing collagen production
  • Strengthening the skin barrier

It remains the gold standard for deep rejuvenation.

How it’s injected

  • Dozens of small injections (like tiny mosquito bites)
  • Local numbing cream applied beforehand
  • Visible bumps for 24–48 hours
  • Mild swelling or redness expected

What Is Needle-Free Rejuran?

Needle-Free Rejuran uses air-pressure, micro-channel, or transdermal infusion devices to deliver PN fragments without needles.

No bumps, no downtime, almost no discomfort.

It focuses on:

  • Hydration
  • Glow
  • Radiance
  • Surface-level texture improvement

It’s gentler, quicker, and beginner-friendly.

How it’s delivered

  • High-pressure infusion or micro-channel diffusion
  • No puncture marks
  • No swelling
  • Makeup can often be worn the same day

Key Differences: Needle-Free vs Injected Rejuran

Here’s a clear side-by-side comparison:

1. Depth of Delivery

Injected Rejuran:

✔ Reaches the dermis (deep layer)
✔ Strong collagen stimulation
✔ Better for scars and aging

Needle-Free Rejuran:

✔ Stays in the upper skin layers
✔ More hydration than remodeling
✔ Better for glow, not deep repair

2. Pain & Comfort

Injected Rejuran:

  • Requires numbing
  • Slight discomfort
  • Temporary bumps

Needle-Free Rejuran:

  • Painless
  • No needles
  • No bumps or marks

3. Downtime

Injected Rejuran:

  • 24–48 hours of visible dots
  • Mild swelling possible

Needle-Free Rejuran:

  • Zero downtime
  • Makeup usually possible immediately

Perfect for business trips, travel, or same-day events.

4. Results

Injected Rejuran:

  • More dramatic and long-lasting
  • Improves elasticity, wrinkles, scars
  • Strengthens thin or damaged skin

Needle-Free Rejuran:

  • Gives glow and hydration
  • Improves skin texture subtly
  • Softer, surface-level improvement
  • Great as maintenance

5. Ideal Candidates

Choose Injected Rejuran if you have:

✔ Acne scars
✔ Uneven texture
✔ Fine lines or early sagging
✔ Sun damage
✔ Thin or aging skin

Choose Needle-Free Rejuran if you want:

✔ Glow without downtime
✔ Hydration boost
✔ Smooth makeup base
✔ Gentle rejuvenation
✔ A pain-free skin booster
✔ A travel-friendly treatment

6. Number of Sessions Needed

Injected:

  • 3 sessions, 3–4 weeks apart
  • Maintenance every 3–6 months

Needle-Free:

  • 3–5 sessions, 1–2 weeks apart
  • Monthly or biweekly maintenance

Which One Is Better?

It depends on your goals:

Best for deep, corrective rejuvenation

➡️ Injected Rejuran

Best for glow, hydration, and no downtime

➡️ Needle-Free Rejuran

Best for beginners

➡️ Needle-Free Rejuran

Best for long-term anti-aging

➡️ Injected Rejuran

Best for events or travel

➡️ Needle-Free Rejuran

Many people in Korea actually do both — injected Rejuran for structural improvements and needle-free sessions for monthly glow.

Final Thoughts

Needle-Free and Injected Rejuran each offer unique benefits.
If you want:

  • Glass-skin radiance
  • Hydration
  • No downtime

Choose Needle-Free Rejuran.

If you want:

  • Collagen rebuilding
  • Scar improvement

Choose Injected Rejuran.

Both treatments complement each other beautifully and continue to rank among Korea’s top skin boosters for good reason.
