What is PDRN? An Expert's Guide To PDRN Skincare

PDRN skincare is quickly becoming one of the most talked-about innovations in skincare, but how does it work, and is it right for your skin? In this guide, we explore everything you need to know, from how PDRN supports skin regeneration to how it compares with well-known ingredients like retinol.

Often associated with in-clinic treatments, including the now well-known salmon sperm facial, PDRN is also becoming more accessible through our everyday skincare.

Whether you’re exploring new ways to support your skin barrier or simply want to understand the science behind salmon PDRN, consider this your starting point.

What is PDRN and how does it work?

Originally used in medical settings to support wound healing, PDRN (polydeoxyribonucleotide) is the latest skincare hype for its ability to help support the skin’s natural repair process.

At its core, PDRN works by encouraging skin regeneration at a cellular level. Once applied, it helps to stimulate your skin’s own renewal, supporting the repair of everyday damage caused by UV exposure and natural ageing.

What does PDRN do for the skin?

Salmon PDRN is highly biocompatible, meaning it works in harmony with your skin to encourage deep restoration. Here is how PDRN for your skin can benefit you:

Daily repair: it acts like a helping hand, encouraging your skin to bounce back from the impact of UV exposure and pollution.
Natural elasticity: by working beneath the surface, PDRN prompts the production of collagen so you can have firmer skin.
Protective barrier: PDRN reinforces your natural defences by supporting ceramide production, helping you stay resilient against environmental stressors and sensitivity.
Lasting hydration: rather than a temporary fix, it improves your skin's own ability to stay hydrated.
Calming: if your skin is feeling overwhelmed, PDRN can help soothe redness and quieten irritation.

Our skin expert, Suzanne Fleming, explains, "Topically, PDRN may provide anti-inflammatory and barrier-support benefits, increasing hydration on the epidermis (AKA outer layer) of our skin".

Is PDRN salmon sperm?

This is one of the most common and often misunderstood questions around the popular ingredient.

To put it simply, yes, traditional salmon PDRN is derived from salmon DNA, specifically from salmon sperm. Don't let this put you off just yet. What’s important to understand is how refined the final ingredient is before it ever reaches your skin.

Through an advanced purification process, all proteins, lipids and impurities are removed. What remains is a highly refined form of genetic material which is designed to be safe for use on the skin. AKA, it contains no active fish proteins and is carefully processed.

For those who prefer alternatives and look for more sustainable options, innovations are also emerging within the space, including plant-derived versions designed to offer similar regenerative support.

Is retinol or PDRN better?

When it comes to choosing between retinol and PDRN, it’s not always about which is better, but which is right for you.

Retinol is well known for accelerating skin renewal and turnover. It works quickly and can deliver visible results, but it isn’t always tolerated by every skin type. It mainly targets pores and fine lines with a focus on ageing effects.
PDRN takes a different approach. It focuses on supporting repair in a more gradual, gentle way. This makes it a considered option if you have more sensitive or broken skin to strengthen your skin barrier over time. It focuses on barrier repair and offers anti-inflammatory benefits.

In many routines, the two can work well alongside each other. While retinol encourages renewal, PDRN supports recovery, creating a more balanced approach to skin regeneration.

If your skin is more reactive or you’re earlier in your skincare journey, starting with PDRN skincare can help build a stronger foundation. From there, more active ingredients like retinol can be introduced in a way that feels comfortable.

Which companies produce PDRN skincare products?

As interest in PDRN continues to grow, more brands are beginning to explore its potential, particularly within Korean skincare.

Rather than following every trend, we focus on the brands that support the skin in a way that feels purposeful, not excessive. When it comes to PDRN we stick to Medicube, who are widely known for its PDRN range, and for good reason.

Supported by dermatologist testing, Medicube is known for creating results-driven formulas that remain gentle and well-tolerated across a range of skin types, and that have a habit of going viral.
