PDRN stands for polydeoxyribonucleotide, a material made from DNA fragments.

00:00:04,667 --> 00:00:10,917
It belongs in a different chemical category from peptides, even when discussed alongside them.

00:00:10,917 --> 00:00:18,375
A small controlled study assigned twenty patients with diabetic foot ulcers to PDRN or a control group.

4
00:00:18,375 --> 00:00:22,250
Researchers measured local tissue oxygenation and tissue changes.

5
00:00:22,250 --> 00:00:28,917
Tissue oxygenation improved in the PDRN group, while the histological analysis did not show a

00:00:28,917 --> 00:00:32,417
statistically significant difference.

7
00:00:32,417 --> 00:00:35,917
Those endpoints need careful interpretation.

00:00:35,917 --> 00:00:41,375
This disease-specific experiment does not validate every PDRN cosmetic product or skin-rejuvenation
