Exosome, EGF, PDRN: three Korean actives buyers keep asking for, and what separates them

Ask ten overseas buyers what they want out of Korea this year and three words come back: exosome, EGF, PDRN. They arrive in one sentence and get sourced as one shopping list.

The one everybody writes into the brief is the one barely anybody makes. That gap — between demand and supply — is more useful to a buyer than any description of what the three molecules do.

The three, briefly

PDRN — polydeoxyribonucleotide, most often derived from salmon DNA. It arrived in cosmetics from clinical use and it is the one with the strongest recognition among consumers who follow Korean dermatology. In skincare it is positioned around barrier support and calming stressed skin. It is currently the highest-demand term of the three in sourcing conversations, which also means it is the one most likely to appear on a label at a token concentration.

EGF — epidermal growth factor. On an ingredient list you will usually find it as sh-oligopeptide-1 rather than "EGF", which matters when you are checking whether a product actually contains what its marketing says. Positioned around elasticity and skin vitality.

Exosome — the newest of the three and the least standardised. "Exosome" describes a delivery vehicle rather than a single defined substance, and the source varies by brand (plant-derived is common in cosmetics). Because there is no shared definition, claims vary enormously between suppliers and comparison is genuinely hard.

The commercial difference

PDRN sells on recognition. EGF sells on a mechanism customers already understand. Exosome sells on novelty — which is the most fragile of the three, because novelty expires and, in several markets, regulators have started asking harder questions about what exosome claims mean.

If you are building a range to last, PDRN and EGF are the safer anchors and exosome is the differentiator on top. If you are building for a launch moment, invert that.

Who carries what

Read the SKU counts as a signal of commitment. One product means the brand is testing the ingredient; three across a routine means the supply chain and claim structure are already settled.

Exosome

A brand appearing in more than one of these lists is worth a second look. It usually means the range is built as a routine rather than as a set of unrelated hero products — and a routine sells the second and third SKU on the strength of the first.

The one check that is not obvious

For EGF, read the INCI rather than the front of the box. It appears as sh-oligopeptide-1; if the marketing says EGF and that string is nowhere on the ingredient list, ask what is actually in there. Of the three, this is the one where the label and the claim most often come apart.
