Understand Your Skin.
Science-backed guidance to help you understand what your skin is signalling — and follow a calm, clinical pathway toward visible improvement with Salmon DNA (PDRN) skincare.
PDRN vs Exosomes vs Peptides
PDRN, exosomes, and peptides are all used in modern skincare to support visible renewal, texture refinement, and recovery. While they are often grouped together, they work in very different ways and serve different roles within a routine.
What is PDRN?
PDRN (Polydeoxyribonucleotide) refers to DNA-derived fragments used in skincare to support visible skin recovery and renewal. It is commonly positioned in routines focused on barrier support, calm regeneration, and tolerance.
What are exosomes?
Exosomes are microscopic vesicles involved in cellular communication. In skincare language, exosome-based ingredients are positioned to support signalling pathways related to renewal, balance, and recovery.
What are peptides?
Peptides are short chains of amino acids used in skincare to support functions such as hydration, firmness, and surface smoothness. Different peptides serve different purposes depending on their structure.
How they compare
| Ingredient | Primary role | Common use |
|---|---|---|
| PDRN | Support regenerative signalling | Recovery, barrier support, texture refinement |
| Exosomes | Support cellular communication | Advanced renewal, balance, recovery routines |
| Peptides | Support structure and function | Firmness, hydration, surface smoothing |
Which should you choose?
Your skin is reactive, stressed, or recovering, or you want a calm renewal pathway.
You are focused on advanced renewal and cellular communication support.
Your goal is firmness, hydration, and surface smoothing.
How to use them together
Many routines combine these ingredients strategically — for example, using PDRN to support recovery, peptides to support structure, and exosomes to support signalling balance.
