Recently, products with polydeoxyribonucleotide (PDRN) can be easily found in pharmacies and cosmetics stores

South Korean outlet Maeil Business Newspaper reports that PDRN-based skincare products, including ampoules, creams and mask packs, are increasingly common in pharmacies and cosmetics stores, with brands competing on advertised ppm figures such as "10,000 ppm." The article cites industry sources and pharmacist Lee Hye-jung of Barun-on-Nuri Pharmacy, who warn that a high ppm figure alone does not indicate product quality, since it reflects only the labeled content of raw material, not its purity. A 10,000 ppm raw material at 1% purity yields only 100 ppm of actual PDRN, while an 800 ppm raw material at 99% purity yields about 792 ppm. Lee advises consumers to also consider raw material sourcing, purification method, molecular weight, and manufacturing quality control rather than relying on ppm numbers alone.
