Tired skin,
from within,healthy again.
The healing masterpiece, placed by hand.
Dryness, fine lines, sagging pores, and sensitivity that reddens easily begin when the skin barrier and inner environment break down. Rejuran places a biocompatible compound extracted from salmon (PN) directly into the dermis, densely replenishing thinned skin and building its power to heal itself. Rejuran Key Doctor and head director Dr. Seojin Jae personally injects it by hand.
Because Rejuran places a highly viscous substance into the dermis, discomfort, bruising, and effectiveness differ greatly with the practitioner’s technique. Instead of uniform machine injection, Karin insists on manual injection by the head director.
Tailored Prescription
For barrier rebuilding and self-regeneration, we prescribe the original Rejuran Healer. If discomfort is a concern and you also want a hydrating glow, we prescribe Rejuran HB Plus, formulated with lidocaine and hyaluronic acid.
Micro Injection
With 15 years of experience, the head director adjusts needle angle and pressure to lay product evenly and densely through the dermal layer, and provides aftercare so that embossing (raised bumps) subsides quickly.
Genuine & Transparent
Karin is an officially certified Rejuran clinic. We open the authentic package before your eyes and provide a certificate of authenticity after treatment, as our promise of honesty.
Rejuran’s main ingredient is PN (polynucleotide), extracted and purified from salmon. Placed evenly in the dermis, PN cares for the tired inner environment of the skin and supports its ability to heal itself.
Rejuran’s main ingredient is PN, a biocompatible compound extracted and purified from salmon.
Using micro-manual injection, the head director places an exact dose of PN into the dermal layer at consistent intervals and depth.
PN cares for the damaged inner environment of the skin and supports the activity of the fibroblasts that produce collagen.
The skin barrier, firmness, and fine lines are gradually refined. The number of sessions and intervals are decided after consultation, and individual results vary.
Two ways to heal
The original Rejuran Healer suits rebuilding the skin barrier from its root and building self-regeneration, while Rejuran HB Plus suits those who want less discomfort along with an immediate hydrating glow. The head director assesses your skin thickness and areas of concern to choose.

Rejuran is a skinbooster that uses PN to restore the skin’s inner environment and barrier, while Ultherapy is a lifting treatment that uses ultrasound heat to lift the sagging SMAS and dermis. Depending on your concerns, you may choose one or plan both, and the head director recommends the right combination after your assessment.
