Rejuran Healer has become one of the most talked-about skin treatments in Korea. Known for its skin-regenerating properties, it's also notorious for being one of the more painful injectable treatments. Here's what you really need to know.

What is Rejuran Healer?

Rejuran Healer is a skin booster injection containing polynucleotides (PN) derived from salmon DNA. It's closely related to PDRN treatments, another popular salmon DNA-based therapy. Unlike fillers that add volume, Rejuran works by:

  • Stimulating your skin's natural healing process
  • Promoting collagen and elastin production
  • Improving skin texture and elasticity
  • Reducing fine lines and scarring
  • Enhancing overall skin quality

The Pain Question: Let's Be Honest

Rejuran has a reputation for being painful, and we won't sugarcoat it—there's truth to this. Here's a realistic breakdown:

Pain Level: 6-8/10 (without numbing)

Why it hurts:

  • Multiple injection points (50-100+ per session)
  • Injected into the superficial dermis
  • The solution itself causes some stinging
  • Areas like under-eyes and forehead are more sensitive

Pain Management Options

  • Topical Numbing Cream: Applied 30-45 minutes before. Reduces pain to 4-5/10
  • Lidocaine Mixed Formula: Some clinics offer Rejuran mixed with anesthetic
  • Sleep Anesthesia: For those with low pain tolerance, receiving treatment under sedation is an option
  • Rejuran HB Plus: A less painful alternative that combines Rejuran with hyaluronic acid, offering similar benefits with reduced discomfort
  • Cold Air Device: Continuous cooling during injection

Treatment Protocol

  • Initial Series: 3-4 treatments, 2-4 weeks apart
  • Maintenance: Every 3-6 months
  • Duration: 15-30 minutes per session
  • Downtime: 1-3 days of small bumps/redness

Results: What to Expect

Timeline:

  • Week 1: Skin feels more hydrated
  • Week 2-3: Improved texture becomes noticeable
  • Week 4-8: Collagen regeneration visible
  • Month 3+: Optimal results after full treatment course

Rejuran Variants

Several versions exist for different needs:

  • Rejuran Healer: Original formula for general rejuvenation
  • Rejuran I (Eye): Thinner formula for delicate under-eye area
  • Rejuran S (Scar): Higher concentration for acne scars
  • Rejuran HB: Combined with hyaluronic acid for added hydration

Cost in Korea

  • Per Session: $350 - $500 USD
  • Full Course (3-4 sessions): $900 - $1,500 USD
  • Combination Treatments: Often bundled with laser for better results
