🇬🇧 Note: In K-Beauty, an ampoule is a more concentrated serum

If you’ve been following Korean skincare lately, you’ve probably noticed one ingredient dominating social media, beauty clinics and product launches alike: PDRN.

PDRN has rapidly become one of K-Beauty’s biggest skincare trends. Today, you’ll find it in serums, ampoules, sheet masks and moisturisers from brands such as Medicube, Genabelle and VT Cosmetics.

But while many brands are only now embracing PDRN, one name has been associated with it for years: Rejuran.

In fact, Rejuran helped bring PDRN-based regenerative treatments into mainstream aesthetic medicine before introducing the technology into topical skincare. So, does the Rejuran Turnover Ampoule live up to its reputation? Let’s take a closer look.

What is pdrn?

PDRN in skincare stands for Polydeoxyribonucleotide (while in injectables it’s Polynucleotide), a purified DNA fragment traditionally derived from salmon.

Before that makes you raise an eyebrow, there’s good science behind it.

Salmon DNA has a remarkably high degree of compatibility with human DNA, making it well suited for regenerative medicine. For years, doctors have used PDRN in wound healing and tissue repair because of its ability to support the body’s natural recovery processes.

Unlike ingredients such as glycolic acid, retinol or vitamin C, PDRN doesn’t work by exfoliating the skin or forcing rapid cell turnover.

Instead, it focuses on creating healthier skin from within by supporting repair mechanisms and encouraging an environment where skin can recover more efficiently.

Research suggests PDRN may help:

  • support skin regeneration
  • improve elasticity
  • encourage collagen production
  • calm inflammation
  • strengthen the skin barrier
  • improve hydration
  • accelerate recovery after skin damage

This is why PDRN has become particularly popular for people dealing with:

  • ageing skin
  • compromised skin barriers
  • post-acne marks
  • redness
  • fine lines
  • dehydrated skin

Why is Rejuran considered the original PDRN Brand?

Many people assume PDRN is simply another skincare trend.

In reality, Rejuran has been working with this technology for years.

The skincare line was developed by PharmaResearch, the South Korean biotechnology company behind the famous Rejuran Healer injectable treatments used by dermatologists and aesthetic clinics throughout Korea.

Rather than inventing PDRN itself, PharmaResearch played a significant role in popularising salmon DNA-based regenerative treatments in aesthetic medicine and eventually adapted the technology for daily skincare through its proprietary c-PDRN® complex.

That medical heritage is one of the reasons Rejuran continues to be viewed as one of the most credible names in PDRN skincare today.

What Is c-PDRN®?

One detail that often gets overlooked is that Rejuran doesn’t simply advertise « PDRN. »

Instead, it uses c-PDRN®, the company’s proprietary cosmetic version of PDRN designed specifically for topical skincare.

While injectable treatments deliver polynucleotides directly into the skin, topical skincare must work very differently.

The c-PDRN® technology is formulated to support the skin barrier and improve overall skin condition through regular daily application, making it suitable for home use.

One thing I appreciate about the Rejuran Turnover Ampoule is that it doesn’t try to overload the formula with dozens of trendy actives.

Instead, the ingredient list focuses on skin recovery.

Some of its key ingredients include:

c-PDRN® (Hydrolysed DNA)

The hero ingredient, derived from wild salmon with a patented D.O.T. technology for deep absorption.

Niacinamide

Helps brighten uneven skin tone, strengthen the barrier and improve overall radiance.

Licorice Root Extract

A well-known soothing ingredient that can help reduce redness while supporting a more even complexion.

Aloe Vera & Calendula

Provide lightweight hydration while calming irritated skin.

Bisabolol

An anti-inflammatory ingredient commonly used in products designed for sensitive skin.

Arbutin

Helps improve the appearance of post-inflammatory hyperpigmentation and uneven pigmentation.

Blackberry Leaf Extract

Antioxidants

Texture and Application

This took some getting used to as the texture can feel a little viscous and rich. But it spreads easily, absorbs quickly and leaves very little residue, making it suitable for layering underneath your other products.

It also fits well into both morning and evening skincare routines.

Who Should Use the Rejuran Turnover Ampoule?

This ampoule is particularly suited to anyone looking to improve overall skin health rather than chasing dramatic overnight results.

It may be especially beneficial if you have:

  • early signs of ageing
  • post-menopausal dryness
  • dehydrated skin
  • a weakened skin barrier
  • dull complexion
  • post-acne marks
  • redness
  • uneven texture

Because it focuses on supporting skin recovery rather than exfoliating aggressively, it also layers well with ingredients like retinol, acids and vitamin C.

Final Thoughts

One thing I always appreciate is when a skincare brand has genuine scientific credibility behind its hero ingredient.

That’s exactly what makes Rejuran stand out.

While many brands are now riding the PDRN wave, Rejuran’s connection to regenerative medicine lends it far more authenticity than brands that have simply added « salmon DNA » to their latest launches.

And it shows. This will now be a staple in my routine.
