Is Your Neck Aging Faster Than Your Face? Rejuran PN Neck Rejuvenation at Rappoel Dermatology Seoul



Most people diligently moisturize and treat their faces but overlook the neck — which is equally exposed to UV damage and gravity. Neck skin has fewer sebaceous glands, naturally lower hydration, and thinner dermis than facial skin, making it age faster. Modern smartphone habits compound the problem, accelerating horizontal neck lines. At Rappoel Dermatology in Seoul, we use Rejuran (polynucleotide / PDRN) injections into the neck dermis to stimulate collagen regeneration, improve skin texture, and visibly reduce neck lines.

Signs of Neck Aging

  • Horizontal neck lines: From platysma tension and skin laxity
  • Rough, dull texture: Accumulated UV damage and slow cell turnover
  • Vertical skin laxity: Fine vertical creases from elasticity loss
  • Tech neck lines: Premature horizontal bands from prolonged phone use

How Rejuran Works on the Neck

Rejuran’s active ingredient — Polynucleotide (PN) derived from salmon DNA — acts as a direct cellular repair signal:

  • Activates fibroblasts to produce new collagen and elastin
  • Improves intrinsic dermal hydration
  • Antioxidant action slows free-radical-driven aging
  • Linear threading injection targets horizontal neck lines directly

Treatment Protocol

  1. Physician assesses neck line depth, distribution, and skin quality
  2. Optional topical anesthesia (30 min pre-treatment)
  3. Systematic grid injection into the neck dermis with fine needles
  4. Post-treatment ice compress
  5. Recommended course: 3 sessions, 3–4 weeks apart

Frequently Asked Questions

Are deep neck lines treatable with Rejuran?
Rejuran works best on mild to moderate neck lines. Deep lines often benefit from a combination approach including platysma botulinum toxin or hyaluronic acid filler. Rappoel assesses the optimal combination at consultation.
Is neck injection more painful than facial injection?
Neck skin is thinner and can feel slightly more sensitive. Rappoel offers topical anesthetic cream applied 30 minutes before the session to significantly reduce discomfort.
Can I go out immediately after treatment?
Yes. Small injection marks typically resolve within 1–2 days. Normal daily activities are fine; avoid intense sweating or exercise on the day of treatment.
Can face and neck be treated in the same session?
Yes. Many patients combine facial and neck Rejuran in a single visit to maximize each trip to Seoul.
What’s the difference between tech neck and regular neck aging?
‘Tech neck’ specifically refers to accelerated horizontal lines from phone use posture; general neck aging involves multiple factors including platysma tension and skin laxity. Both respond well to Rejuran; deeper lines may benefit from adding botulinum toxin.
