PN — short for polynucleotide — is one of the most talked-about ingredients in Korean skincare and skin boosters right now. If you have seen it pop up everywhere lately and wondered what it actually is, here is the plain-English version.
What is polynucleotide?
Polynucleotides are highly purified chains of nucleotides — the same building blocks that make up DNA. In skin boosters, PN is most commonly derived and purified from salmon, then filtered to a high grade so it is biocompatible with human skin.
How PN works
Rather than sitting on the surface, PN is designed to support the skin's own repair and renewal processes. It is understood to help create a better environment for your fibroblasts — the cells responsible for producing collagen and elastin — to do their job.
Because of that, the effect is gradual. PN is not an instant "filler" result; it works with your skin over time as it naturally regenerates.
What to expect
- Changes build over weeks, not overnight.
- Improvements are typically described in terms of skin quality — smoothness, hydration, and firmness — rather than added volume.
- Consistency matters more than any single application.
PN vs PDRN
You will often see PDRN mentioned alongside PN. PDRN (polydeoxyribonucleotide) is a specific, smaller fraction within the broader polynucleotide family. They are related and often discussed together; PN generally refers to the larger, longer-chain molecules.
