About this site

PDRN is discussed everywhere in aesthetics, but the published literature is scattered across wound-care journals, in vitro papers and animal models — and almost never assembled in one place with its limits attached. This site collects that literature, grades it study by study, and keeps every claim tied to its source, so you can see how far the evidence actually goes.

The site exists to bridge the gap between that research and the decisions people make about regenerative skincare — what a product claims, what the studies behind it show, and where the evidence stops.

Evidence first

Every claim on the site is tied to a published study and labelled with its evidence grade, so the strength of what you are reading is always visible.

Independent

No brand, clinic or manufacturer pays us to cover or recommend anything. No sponsored placements, no clinic recommendations, no pricing.

Plain language

Complex research translated into terms you can use, with the limits of each study kept in plain sight.

  • Educational reference only. This site does not provide medical advice, treatment courses, injection counts, clinic recommendations or price recommendations.
  • PDRN is not approved by the FDA for injection or any therapeutic use. Topical and injectable PDRN are parallel facts under different regulatory pathways and must not be directly equated.
  • PN is not PDRN. Evidence grades are labelled on every factual element; in vitro and animal research is never described as clinical efficacy.
