If you’ve ever searched for glowing skin, refined pores, or firm facial contours, you’ve likely come across two powerhouse skincare ingredients: PDRN (Polydeoxyribonucleotide) and PN (Polynucleotide). Alongside Hyaluronic Acid, these ingredients have become the gold standard in Korean dermatology and aesthetic treatments. In this article, we’ll explore how each of these ingredients transforms the skin — and why Elreju, a cutting-edge skin booster that combines them all, might be the perfect pain-free treatment you’ve been looking for.
What Is PDRN and How Does It Help the Skin?

PDRN is a naturally derived compound extracted from salmon DNA, widely known for its powerful regenerative properties. It promotes cell renewal, stimulates collagen production, and enhances wound healing, making it a popular choice in treatments for acne scars, fine lines, and overall skin rejuvenation.
PDRN is particularly effective for damaged or aging skin, helping to restore elasticity and firmness. It’s often used after laser treatments to support faster recovery and strengthen the skin barrier.
The Role of PN in Skin Recovery and Texture Improvement

PN (Polynucleotide) is a more purified and potent form of PDRN that offers enhanced skin repair and texture improvement. It works by revitalizing damaged cells, tightening enlarged pores, and reinforcing the skin’s natural barrier. PN has gained attention in treatments like Rejuran Healer, which are renowned in Korea for delivering youthful, smoother skin.
These polynucleotide-based treatments are especially loved by those looking for natural, subtle enhancements without drastic cosmetic procedures.
Why Hyaluronic Acid Is a Must for Hydrated, Plump Skin
Hyaluronic Acid (HA) is a naturally occurring molecule in the skin that can hold up to 1,000 times its weight in water. It’s essential for maintaining deep hydration and a healthy skin barrier.
Modern skin boosters often include both high-molecular and low-molecular Hyaluronic Acid to provide intense hydration across all skin layers. The result? Dewy, glowing skin with improved elasticity and volume — perfect for combating dullness, dryness, and early signs of aging.
Introducing Elreju: A Next-Level Skin Booster That Combines It All

If you’re wondering whether there’s a single solution that includes all these powerful ingredients — the answer is yes. Meet Elreju, one of the most advanced skin boosters available in Korea.
Elreju combines:
- High-purity PDRN and PN for deep regeneration
- A mix of high and low molecular Hyaluronic Acid for layered hydration
- Additional skin-revitalizing components like Madecassoside, Glutathione, and Tranexamic Acid for brightening, calming, and anti-aging effects
What sets Elreju apart is not just its multi-functional approach, but also its pain-free application. Instead of traditional microneedles, Elreju uses a pumping tip device that gently delivers the formula into the skin with minimal discomfort and no visible downtime. You can receive the treatment and return to your daily routine right away — no redness, no bruising, no worries.
