Polydeoxyribonucleotide (PDRN) is a mixture of DNA fragments (typically derived from salmon or trout sperm) that has tissue-repair, anti-inflammatory, and regenerative effects. It works mainly by activating the adenosine A2A receptor, which helps stimulate cell growth, angiogenesis (new blood vessel formation), and tissue healing.
Here are the main applications of Polydeoxyribonucleotide:
1. Aesthetic medicine & dermatology
This is the most well-known use.
Skin rejuvenation
- Improves skin elasticity and hydration
- Enhances dermal thickness
- Reduces fine lines and photoaging effects
Wound healing
- Speeds recovery after lasers, microneedling, or chemical peels
- Helps repair damaged skin barriers
Scar improvement
- Used for acne scars and post-surgical scars
- Promotes more organized tissue regeneration
Injection therapy (“skin boosters”)
- Intradermal injections for skin regeneration (often in clinics)

2. Chronic wound treatment
Used in medical settings for difficult-to-heal wounds:
- Diabetic foot ulcers
- Pressure ulcers (bedsores)
- Chronic vascular ulcers
- Post-surgical wounds with delayed healing
Polydeoxyribonucleotide supports tissue regeneration and improves local blood supply.
3. Ophthalmology (eye medicine)
Polydeoxyribonucleotide is used in some countries as eye drops or injections for:
- Corneal injury repair
- Dry eye disease (supporting epithelial healing)
- Post-surgical corneal recovery (e.g., after LASIK or PRK)
It helps restore damaged corneal epithelial cells.
4. Orthopedics & musculoskeletal therapy
Research and clinical use include:
- Tendon and ligament injuries
- Osteoarthritis (adjunct therapy)
- Muscle injury recovery
It may reduce inflammation and promote connective tissue repair.
5. Urology (limited use in some regions)
- Tissue repair in bladder mucosal damage
- Supportive therapy for chronic inflammatory conditions (investigational in many places)

6. Post-procedure recovery in medicine and aesthetics
Polydeoxyribonucleotide is frequently used after:
- Laser resurfacing
- RF microneedling
- Dermal filler procedures (to reduce downtime and inflammation)
Summary
Polydeoxyribonucleotide is mainly used as a regenerative and anti-inflammatory agent, especially in:
- Skin rejuvenation and aesthetic treatments
- Chronic wound healing
- Eye tissue repair
- Supportive musculoskeletal regeneration
