Rejuran Healer & Skin Boosters

Biological Dermal Regeneration with Polynucleotide (PN) & Multi-Nutrient Boosters

At Jenny Clinic, Rejuran Healer & Skin Boosters focus on restoring the fundamental physiological health of the dermis rather than merely masking surface dryness. Under the clinical leadership of Representative Director Dr. Minjung Cho, we administer authentic, KFDA-cleared biocompatible skin boosters tailored to repair compromised skin barriers, thicken thin dermis, and balance sebum-hydration homeostasis.

Core Bio-Regenerative Formulations

• Authentic Rejuran Healer (2% Polynucleotide PN): Composed of highly purified, biocompatible salmon-derived DNA fragments (Polynucleotides) that selectively bind and activate adenosine A2A receptors. This biological cascade stimulates fibroblast proliferation, promotes extracellular matrix (ECM) remodeling, thickens thin or senescent dermis, repairs UV- and laser-damaged skin barriers, and normalizes oil-water balance.
• Rejuran HB Plus (Hydro Boost + Lidocaine): A synergistic combination of Polynucleotide (PN), cross-linked and non-cross-linked Hyaluronic Acid (HA), and integrated Lidocaine. Designed for dry, sensitive, or pain-averse patients seeking both cellular regeneration and immediate hydro-luminosity with significantly reduced procedural discomfort.
• Retuo & Filorga NCTF 135HA: Advanced cellular revitalization complexes combining uncrosslinked hyaluronic acid with over 50 essential micronutrients—including amino acids, coenzymes, vitamins, minerals, and antioxidants—to combat oxidative stress and restore radiant skin tone.

Dual Delivery Systems: Physician Intradermal Injection vs. Mirajet / CureJet

To maximize bioavailability within the papillary dermis while respecting each patient's comfort threshold and schedule, Jenny Clinic offers two specialized delivery protocols:

1. Meticulous Physician Intradermal Micro-Papule Injection: Hand-injected point-by-point into the superficial dermis by our physicians to ensure uniform micro-droplet deposition across the cheeks, periorbital lines, neck rings, and forehead with minimal product loss.
2. Mirajet / CureJet Needle-Free Pressure Jet System: Utilizing high-velocity micro-jet kinetic pressure (including laser-induced or electromagnetic micro-jet propulsion), Mirajet and CureJet disperse nano-droplets of skin booster laterally into the dermis without physical needles—minimizing bruising, shortening embossing recovery time, and simultaneously triggering mechanical micro-subcision for fine pores and scars.

Clinical Indications & Recommended Regimen

• Sensitized, Red, or Laser-Thinned Skin Barriers: Rejuran Healer thickens the dermal layer and calms chronic barrier inflammation.
• Dehydrated Inner Skin with Surface Sebum Imbalance: Normalizes transepidermal water loss (TEWL) and refines enlarged pores caused by dehydration.
• Fine Periorbital, Perioral & Neck Crepiness: Restores elasticity in delicate zones where heavy cross-linked fillers are contraindicated.

Clinical Safety Disclaimer: Individual results vary depending on skin barrier integrity, age, and lifestyle factors. Temporary post-procedural effects may include localized micro-papules (embossing), mild redness, pinpoint bruising, or transient swelling at injection sites, which generally subside within 1 to 3 days. Please consult with our physicians regarding any history of seafood/fish allergies or active skin infections prior to treatment.
