A polynucleotide (PN) skin booster that helps the skin repair from within.
"This is a regenerative treatment, working at the level of the skin's own collagen environment rather than coating the surface."
— Dr. Choi Dong-Il, Director
A skin booster that stimulates collagen regeneration in damaged skin from the inside out.
Rejuran Healer is a regenerative skin booster that stimulates collagen regeneration in damaged skin. Its active ingredient, polynucleotide (PN), is heat-stable and well tolerated by the body, making it a safe option even for sensitive skin.
By activating the skin's own renewal capacity, Rejuran improves the dermal environment, restores the underlying skin structure, and supports healthier epidermis and dermis. Patients commonly notice firmer skin and a steady recovery from prior surface damage as the treatment course progresses.
※ Because it is based on purified DNA fragments, immune reactions are uncommon.
Short downtime with same-day return to normal activity.
Heat-stable, purified DNA fragments derived under pharmaceutical-grade conditions.
Restores both epidermal and dermal structure rather than treating only the surface.
Uncommon for an immune reaction to develop, with minimal foreign-body response.
Dr. Choi Dong-Il, with 22 years of practice.
Five common situations in which Rejuran tends to be the right fit.
Concerns about skin
texture and tone
Disrupted oil and water
balance with excess sebum
Loss of firmness
and fine lines
Skin that needs to recover
from frequent prior treatments
Patients who want a
regenerative, gentle approach
Rejuran works inside the skin itself. Polynucleotide stimulates collagen production within the dermis, restoring the underlying skin architecture so that texture, firmness, and fine lines improve gradually over the course of a treatment plan.
Purified DNA fragments rarely provoke an immune response and carry minimal foreign-body concern.
Across sessions one through four, the skin gradually firms and the surface quality refines as renewal accumulates.
A four-stage recovery program where results build session over session.
Session 1 → 2 → 3 → 4, with effects compounding throughout.
