Rejuran PN collagen stimulation therapy at Kind Global Clinic Myeongdong uses PN polynucleotide micro-injections at ₩290,000–₩490,000 ($207–$350 USD) per session to activate your skin's own fibroblasts to synthesize collagen type I and III — 18.4% dermal density increase after 3 sessions — performed by co-directors Dr. Lee Wonjin or Dr. Lee Kangin.
Collagen stimulation therapy at Kind Global Clinic Myeongdong is based on Rejuran PN (polynucleotide) — a Korean-manufactured injectable by Pharma Research that activates endogenous collagen synthesis through a defined receptor pathway. Unlike dermal fillers that add foreign volume, Rejuran PN collagen stimulation therapy triggers your skin's own fibroblasts to produce new collagen type I and III — the structural proteins responsible for skin firmness, elasticity, and dermal density.
The mechanism: PN polynucleotide binds adenosine A2a receptors on dermal fibroblasts, elevating intracellular cAMP and activating TGF-β1-mediated SMAD2/3 signaling. This transcription cascade upregulates COL1A1 and COL3A1 gene expression — resulting in measurable 34% and 28% increases in collagen type I and III mRNA at 72 hours (Park et al. 2022). The clinical outcome after 3-session collagen stimulation therapy protocol at 4-week intervals: 18.4% dermal density increase by ultrasonographic measurement (Lee et al. 2020 Korean RCT, n=72).
Collagen stimulation therapy at Kind Global Clinic Myeongdong is performed personally by co-directors Dr. Lee Wonjin (KR License 143124) or Dr. Lee Kangin (KR License 141247) — 200-300 micro-injection points per session, same physician across your full series, Rejuran PN vial lot number documented on your chart.
