What is PDRN?

PDRN (Polydeoxyribonucleotide) is an advanced skincare ingredient that helps support the skin's natural renewal process. It is widely used in Korean skincare and professional aesthetic treatments because it helps skin look healthier, stronger, and more resilient over time.

PDRN is especially loved in routines focused on skin recovery, hydration, and improving the appearance of tired or stressed skin.

Quick routine tip

Apply a PDRN serum after cleansing and before moisturizer. Pair it with hydrating ingredients like hyaluronic acid and barrier-supporting ingredients like ceramides to help your skin feel comfortable and well cared for.

During periods when your skin feels stressed or dehydrated, keep the rest of your routine simple and focus on hydration and barrier support.

Notes

PDRN has become one of the most talked-about ingredients in modern Korean skincare because of its focus on supporting healthier-looking skin rather than aggressively resurfacing it.

Many cosmetic PDRN ingredients are derived from purified DNA fragments (historically from salmon), while newer biotechnology-derived alternatives are also becoming available.

At gbb, we appreciate PDRN because it reflects our philosophy of steady, gentle care. Instead of pushing the skin, it complements routines centered on comfort, resilience, and long-term skin health—helping your skin feel supported, one daily ritual at a time.
