high-purity PDRN Polydeoxyribonucleotide salmon derived DNA fragment for tissue regeneration&Wound healing

PDRN, its INCI name is DNA sodium (also known as salmon DNA sodium), and its full name is polydeoxyribonucleotide. At the same time, it is also the core ingredient of the "salmon water-light product" commonly used in medical aesthetics. It is an optimized DNA fragment extracted from the seminal vesicle cells of salmon (salmon or trout), which is very similar to human DNA. Chemicalbook has the function of stimulating the regeneration of collagen and elastic fibers, and is applied in the field of skin care. It can resist inflammation, repair, reduce redness, improve skin tone, and stimulate collagen synthesis. Its chemical property is white to yellow to beige powder, and it is soluble in water (10mg/ml).

When applied to the skin, PDRN can resist inflammation, repair damage, reduce redness, even out skin tone, and stimulate collagen production. In recent years, the application scope of PDRN has expanded to the fields of medical aesthetics and skin care. The DNA of salmon sperm can be used as a research reagent and is widely applied in molecular biology, pharmacology and other research areas. It is strictly prohibited from being used on humans. Main application fields:
Medical and wound repair:
- Acceleration of wound healing (e.g. diabetic foot ulcers, venous ulcers)
- Re-epithelialization of burns, laser vaporization injuries, burns
- Post-operative medical repair (e.g. nasal septum reshaping, corneal resection surgery)
- Reduction and healing of oral mucositis, radiation dermatitis
Medical aesthetics:
- "Salmon needle" for skin regeneration, acne pit repair, skin quality improvement
- Pain management for shoulder joints, knee joints, plantar fasciitis, etc. 
- Facial photoaging treatment, scar repair
Cosmeceuticals (topical products):
- Barrier repair: suitable for sensitive skin, hormone acne, baby red bottom
- Anti-aging: stimulates type I/III collagen synthesis, inhibits MMPs, reduces fine lines and sagging
- Hydration: locks in moisture through hydrogen bonds and promotes hyaluronic acid production
- Anti-inflammatory and soothing: reduces TNF-α, IL-1β, enhances IL-10, improves redness and irritation

• Salmon DNA can be used as a research reagent and is widely applied in molecular biology, pharmacology and other research fields. It is strictly prohibited for human use. The mechanism of action of PDRN mainly consists of two aspects. On one hand, it participates in the "Chemicalbook salvage pathway" to provide raw materials for DNA synthesis of cells; on the other hand, it acts as an agonist of adenosine receptor A2A, participating in the activation or inhibition of multiple pathways, regulating downstream products and thereby exerting various pharmacological effects. PDRN (sodium salmon DNA) has been fully verified for its effects in the medical beauty field and has been applied in the "Salmon Water Light Medical Beauty Project" to repair damaged skin, sensitive skin, enhance the barrier, soothe and repair, and resist oxidation and aging. When applied to skin care products, it can: reduce inflammation caused by Chemicalbook substances, rebuild and restore the repair ability and defense barrier, repair skin sensitivity, inflammation and other problems; stimulate collagen regeneration, repair skin microcirculation, promote the growth of new cells, metabolize damaged cells, activate the activity of aging cells, and moisturize dry, rough, and wrinkled skin problems.
