Anti Inflammatory Healing PDRN Skincare Medical Grade Polynucleotide Dermal

1. Product Description

• PDRN (Polydeoxyribonucleotide) is a high-purity medical aesthetic grade bioactive nucleic acid raw material extracted from natural deep-sea salmon DNA. With a unique human-skin bionic nucleic acid structure, it possesses ultra-high cell homology and excellent biocompatibility, featuring superior transdermal penetration and skin affinity. Different from ordinary single-effect soothing ingredients, PDRN integrates cell activation, inflammatory stabilization, barrier reconstruction and anti-aging rejuvenation, targeting damaged, sensitive and aging skin basal problems. It effectively repairs postoperative micro-lesions, relieves redness and dry sensitivity, improves dull and sagging skin texture. With medical-grade mild safety, stable molecular activity and high formula compatibility, it is widely used in high-end medical aesthetic repair products and professional functional skincare formula development.

2. Product Performance

• Efficient Transdermal Penetration Performance: PDRN adopts optimized small-molecule nucleic acid structure, which can quickly penetrate the epidermal gap and act on basal layer and dermal skin tissue. It delivers fast-acting soothing and repairing effects without surface residue, realizing efficient skin absorption and utilization.
• Rapid Anti-Inflammatory & Stabilizing Performance: It can rapidly inhibit excessive inflammatory response of sensitive skin, effectively relieve acute redness, flushing and stinging caused by external stimulation and minimally invasive operations, and quickly restore skin stable state.
• Persistent Cell Repair & Regeneration Performance: Continuously activates dermal fibroblast vitality, accelerates micro-wound healing and epidermal tissue renewal, maintains long-term cell proliferation activity, and gradually improves fragile and damaged skin texture.
• Stable Anti-Aging & Brightening Performance: Stably promotes collagen and elastic fiber synthesis, improves skin laxity and fine lines caused by aging, accelerates metabolic excretion of dull factors, and maintains long-term translucent and firm skin condition.
• Excellent Formula Stability Performance: Possesses stable physical and chemical properties, resistant to oxidation and activity attenuation during processing and storage. It can be perfectly dispersed in aqueous, essence and cream systems without stratification or precipitation, ensuring consistent batch efficacy.

3. Core Efficacy

• Soothe Sensitivity & Stabilize Skin Condition: Effectively inhibits inflammatory factor release, relieves skin redness, dry itching and tingling sensitivity caused by environmental stimulation, hormone damage and medical aesthetic surgery, and balances skin microecology.
• Repair Skin Barrier & Enhance Resistance: Replenishes skin intercellular nutrients, promotes stratum corneum repair and regeneration, fills epidermal texture gaps, strengthens skin natural defense barrier, and reduces external irritation invasion.
• Accelerate Wound Healing & Postoperative Recovery: Activates skin cell self-healing ability, speeds up the repair of postoperative micro-wounds and damaged skin tissues, shortens the recovery cycle of medical aesthetic skin, and improves postoperative dry peeling and redness problems.
• Anti-Aging Firming & Wrinkle Smoothing: Stimulates endogenous collagen proliferation, improves skin sagging and loose texture, fades dry lines and shallow fine lines, and restores skin elasticity, firmness and delicate touch.
• Hydrating Brightening & Translucent Rejuvenation: Improves basal skin metabolic circulation, accelerates the discharge of aging waste and dull pigments, improves yellowish and dull skin tone, evens skin texture, and creates glossy and youthful translucent skin.

4. Production Process

• High-Quality Natural Raw Material Screening: Select high-activity fresh deep-sea salmon DNA as the core raw material, strictly screen raw material freshness, activity and purity indicators, remove defective and impure raw materials, and ensure pure natural high-quality raw material sources.
• Low-Temperature Bionic Biological Extraction: Adopt low-temperature constant-pressure enzymatic hydrolysis and targeted nucleic acid separation technology, avoid high-temperature destruction of nucleic acid molecular activity, completely retain the complete biological activity and cell repair performance of PDRN active molecules.
• Multi-Stage Precision Purification & Impurity Removal: Through multi-layer ultrafiltration, membrane molecular interception and high-precision purification process, thoroughly remove residual proteins, macromolecular invalid fragments, bacteria and impurities to upgrade to medical aesthetic high-purity grade.
• Biological Molecular Activity Stabilization: Adopt professional molecular embedding and activity locking technology to fix PDRN active structure, prevent molecular oxidation and activity attenuation, and ensure stable and durable repair efficacy of each batch of raw materials.
• Aseptic Packaging & Strict Batch Inspection: Complete refining, drying and sealed packaging in dust-free sterile workshop. Each batch passes strict HPLC purity detection, activity analysis and microbial inspection to meet medical-grade safety and quality standards.
