The burned-in captions and transcript carry the scientific claims and their limitations. The visuals are conceptual illustrations, not validated molecular models or experimental images. The video has no voice or audio. The full explanation is visible on screen; optional accessible captions are available in the player.
Read every result in its study context. A cell experiment, animal model, exploratory analysis and controlled human trial answer different questions.

Transcript
PDRN | DNA-derived material
PDRN stands for polydeoxyribonucleotide, a material made from DNA fragments. It belongs in a different chemical category from peptides, even when discussed alongside them. [1]
HUMAN STUDY | Diabetic foot ulcers
A small controlled study assigned twenty patients with diabetic foot ulcers to PDRN or a control group. Researchers measured local tissue oxygenation and tissue changes. [1]
Oxygenation and histology are different endpoints
Tissue oxygenation improved in the PDRN group, while the histological analysis did not show a statistically significant difference. Those endpoints need careful interpretation. [1]
No automatic transfer to cosmetic products
This disease-specific experiment does not validate every PDRN cosmetic product or skin-rejuvenation claim. Manufacturing, formulation, delivery and the intended outcome all matter. [1]
