The Science Behind Rejuran: How PDRN is Revolutionizing Skin Rejuvenation

Imagine a treatment that doesn't just mask aging but repairs your skin from within—using bioactive polynucleotides to stimulate cellular regeneration and unlock your skin's natural healing potential.

What is Rejuran?

Rejuran is an innovative skin treatment that uses PDRN (Polydeoxyribonucleotide), a substance derived from highly purified salmon DNA. While the concept of injecting DNA fragments might sound complex, the science behind it is fascinating and the results speak for themselves.

The Treatment Experience

A typical Rejuran treatment takes approximately 30-45 minutes. For your comfort, we apply a topical numbing cream before the procedure to minimize any discomfort from the injections. We also offer additional pain relief options for those with heightened sensitivity.

What's more, we can combine Rejuran with complementary treatments tailored to your specific skin concerns and goals, enhancing your results and providing a truly customized approach to skin rejuvenation. Most patients experience minimal downtime, with some experiencing small injection marks or mild swelling that typically subsides within 24-48 hours.

The Science-Backed Bottom Line

As a cosmetic physician committed to evidence-based treatments, I'm particularly impressed by the growing body of research supporting PDRN's effectiveness. Rejuran isn't just another trendy treatment—it represents a significant advancement in our understanding of skin regeneration.

In a clinical trial involving 150 patients with various skin concerns, researchers noted that PDRN not only improved visible signs of aging but also enhanced the skin's overall health markers, including hydration, barrier function, and cellular turnover (Kwon et al., 2021).

The Scientific Foundation: How PDRN Works

At its core, Rejuran works through a remarkable biological process. When PDRN is injected into the skin, it:

  1. Activates cell regeneration by binding to specific receptors (adenosine A2A) on skin cells

  2. Stimulates fibroblasts to produce more collagen and elastin

  3. Improves blood circulation in treated areas

  4. Reduces inflammation while supporting tissue repair

Clinical Evidence: What the Research Shows

Clinical studies consistently demonstrate that PDRN treatments deliver impressive results. Let's examine what the science tells us:

Study 1: Younger-Looking Skin with Improved Elasticity

PDRN (Polydeoxyribonucleotide) treatments help stimulate collagen production, which reduces fine lines and improves skin firmness. Studies show it works by repairing damaged skin cells and slowing down skin aging, leading to a smoother, more youthful complexion. [3]

Study 2: Faster Healing for Cuts, Scars & Skin Damage

PDRN has been clinically proven to speed up wound healing by promoting skin regeneration. In human trials, it helped repair skin up to 92% faster than untreated wounds, making it effective for post-surgery recovery, acne scars, and sun damage repair. [4]

Study 3: Long-Term Skin Renewal & Protection

Unlike temporary cosmetic fixes, PDRN strengthens the skin’s natural barrier over time by boosting key proteins like fibronectin and filaggrin. This means longer-lasting hydration, fewer wrinkles, and better resistance to environmental damage. [3]

What Makes Rejuran Different?

Unlike many cosmetic treatments that provide temporary results by simply adding volume or freezing muscles, Rejuran works at the cellular level to actually improve your skin's condition from within. This means:

Natural-looking results without changing facial expressions

Progressive improvement that continues even after treatment

Addresses multiple concerns simultaneously (wrinkles, elasticity, texture, and tone)

Complements other treatments you may already be using E.g. Neurotoxin, Laser or Biostimulator

Is Rejuran Right for You?

Rejuran is particularly effective for:

  • Fine lines and wrinkles

  • Skin laxity and loss of elasticity

  • Dull, uneven skin texture

  • Acne scarring

  • Sun-damaged skin

  • Thin, crepey skin around the eyes

The ideal candidate is anyone looking for natural skin rejuvenation without dramatic changes to their appearance. Many patients begin seeing results after just 2-3 sessions, with optimal results typically achieved after 3-4 treatments.
