PDRN Skincare Explained: The Korean Trend in 2026

PDRN is one of the biggest ingredient trends in Korean skincare. You will find it in serums, capsule creams, eye creams and even lip masks from brands like medicube and ANUA. But what is it, what can a cosmetic product really do, and how do you fit it into a routine? Here is a clear explanation.

What is PDRN?

PDRN stands for polydeoxyribonucleotide, a mixture of DNA fragments, often derived from salmon. In Korea, PDRN became famous through injectable clinic treatments, sometimes nicknamed ‘salmon injections’. Skincare brands then adopted the ingredient in creams and serums.

PDRN in creams vs clinic treatments

It is important to separate the two. Clinic treatments are medical procedures performed by professionals. A cream or serum that contains PDRN is a cosmetic product applied to the surface of the skin. Cosmetic PDRN products are generally positioned for hydration, skin conditioning and a smoother, healthier-looking complexion, not for the results of a clinic treatment.

Popular PDRN products

• medicube PDRN Pink Peptide Serum: the serum that helped popularize the trend, combining PDRN with peptides.
• medicube PDRN Pink Collagen Capsule Cream: a capsule cream pairing PDRN with collagen.
• medicube PDRN Pink Peptide Eye Cream: for the delicate under-eye area.
• medicube PDRN Pink Collagen Volume Multi Balm: a 10 g stick with Volufiline, PDRN and collagen for targeted areas.
• medicube PDRN Lip Sleeping Mask: an overnight lip treatment.
• ANUA PDRN Hyaluronic Acid Capsule 100 Serum: PDRN combined with hyaluronic acid for hydration.

How to use PDRN products

1. Cleanse and apply toner.
2. Apply the PDRN serum on slightly damp skin.
3. Follow with moisturizer or a PDRN cream.
4. Use sunscreen in the morning.

PDRN products are generally easy to combine with other ingredients such as hyaluronic acid, peptides and niacinamide. Introduce one new product at a time.

Who should be careful?

• People with fish allergies should check the source of PDRN on the label and ask a pharmacist or doctor.
• Anyone with sensitive skin should patch test first.
• If a balm or cream also contains retinol, use sunscreen and introduce it slowly.
