What is PDRN in skincare? Benefits, Types and Best Korean Products (UK)

PDRN is one of the fastest-growing ingredients in Korean skincare, widely used in dermatology clinics and advanced aesthetic treatments. Known for supporting skin repair, improving elasticity and strengthening the skin barrier, PDRN is now appearing in some of the most innovative Korean creams, serums and treatments available in the UK.

Once found primarily in professional treatments, PDRN is now appearing in advanced Korean creams, serums and masks, including pharmacy bestsellers that regularly sell out in Korea.

If you’ve been seeing PDRN skincare trending and wondering what it actually does, here’s everything you need to know. 

What is PDRN?

PDRN (polydeoxyribonucleotide) is a DNA-derived ingredient most commonly extracted from highly purified salmon DNA. In Korean dermatology, it is widely used to support skin regeneration and recovery.

In topical skincare, PDRN is associated with:

• Supporting skin repair

• Improving the appearance of elasticity

• Strengthening the skin barrier

• Reducing the look of fine lines

• Enhancing overall skin resilience

Unlike aggressive resurfacing ingredients, PDRN works by supporting the skin’s natural renewal processes, making it especially appealing for sensitive, compromised or post-acne skin.

Different types of PDRN in skincare:

As the ingredient evolves, brands are developing different PDRN sources:

Salmon-Derived PDRN

The most widely known form, used in many Korean pharmacy formulations. Known for high purity and strong regenerative support.

Example:
Medicube PDRN Pink Peptide Serum
Dr. Reju-All Advanced PDRN Rejuvenating Cream

Rice-Derived PDRN

A plant-based alternative derived from rice, designed to deliver similar renewal support while appealing to those seeking non-animal sources.

Example:
Eqqualberry Purple PDRN Pore Minimizing Serum

CICA PDRN

A variation combining PDRN technology with centella-based compounds for added calming and barrier support.

Example:
Mary & May Spicule Collagen PDRN Cream

Why is PDRN trending in Korean Skincare?

Several factors have driven PDRN’s rise:

• Increased demand for barrier-repair skincare
• Growth of skin regeneration treatments in Korea
• Popularity of pharmacy-led brands
• Shift away from harsh exfoliation toward repair

Rather than stripping or over-exfoliating, modern Korean skincare increasingly prioritises rebuilding and strengthening the skin, which aligns directly with PDRN’s benefits.
