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