PN vs PDRN Skin Rejuvenation
PN vs PDRN Skin Rejuvenation
PN (Polynucleotide) and PDRN (Polydeoxyribonucleotide) are two regenerative ingredients widely used in Korean skin rejuvenation treatments. Both are derived from salmon DNA and are designed to improve skin healing, elasticity, and overall quality, but they differ in molecular structure, depth of action, and clinical focus. PN is generally considered a stronger structural skin-regeneration treatment, while PDRN is often used for healing, recovery, and anti-inflammatory skin repair.
Treatment Focus
PN (Polynucleotide)
- Deep dermal regeneration
- Skin elasticity improvement
- Collagen support
- Texture refinement
- Long-term structural rejuvenation
PDRN (Polydeoxyribonucleotide)
- Tissue healing and recovery
- Anti-inflammatory support
- Barrier repair
- Post-procedure healing
- Early-stage skin rejuvenation
How They Work
PN
- Contains longer-chain polynucleotide fragments
- Acts as a scaffold for tissue regeneration
- Stimulates fibroblast activity and collagen production
- Improves dermal structure and elasticity
PDRN
- Contains shorter DNA fragments
- Activates cellular repair pathways (A2A receptor pathway)
- Enhances microcirculation and tissue healing
- Reduces inflammation and supports recovery
Ideal Candidates
PN
- Thin or aging skin
- Loss of elasticity
- Fine lines and crepey texture
- Enlarged pores and rough texture
- Patients seeking stronger anti-aging effects
PDRN
- Sensitive or inflamed skin
- Post-laser or post-procedure recovery
- Redness and irritation
- Early skin aging
- Patients needing skin healing rather than major restructuring
Aesthetic Results
PN Results
- Firmer and denser skin
- Improved elasticity
- Smoother texture
- Reduced fine lines
- More resilient skin over time
PDRN Results
- Calmer, less reactive skin
- Improved hydration and glow
- Faster recovery after treatments
- Reduced redness and irritation
- Healthier overall skin appearance
PN tends to create more noticeable structural improvement, while PDRN produces a stronger healing and soothing effect.
Speed of Results
PN
- Gradual improvement over 2–8 weeks
- Best results after a series of treatments
- Cumulative collagen remodeling
PDRN
- Earlier improvement in hydration and redness
- Faster visible recovery benefits
- Results often noticeable within days to weeks
Longevity of Results
PN
- Typically lasts 6–12 months
- Longer-lasting structural skin improvement
PDRN
- Typically lasts 3–6 months
- Often used in maintenance or recovery protocols
Recovery and Downtime
PN
- Small injection bumps for 1–3 days
- Mild swelling or bruising possible
- Minimal downtime overall
PDRN
- Very mild swelling or redness
- Quick recovery
- Often performed alongside other procedures
Both treatments are minimally invasive and generally well tolerated.
Cost Comparison (Average Range in KRW)
PN Treatments (e.g., Rejuran Healer)
- ₩300,000 – ₩800,000 per session
PDRN Treatments
- ₩150,000 – ₩500,000 per session
PN is usually more expensive because it is positioned as a higher-intensity regenerative treatment.
Benefits of Each Treatment
Benefits of PN
- Strong collagen stimulation
- Improves skin density and elasticity
- Long-lasting anti-aging effects
- Better for structural skin rejuvenation
- Excellent for thin, aging skin
Benefits of PDRN
- Promotes tissue healing
- Reduces inflammation and redness
- Enhances recovery after lasers or microneedling
- Improves hydration and skin comfort
- Suitable for sensitive skin types
Which Is Better?
PN may be better if you:
- Want stronger anti-aging results
- Have thin, lax, or aging skin
- Want improved firmness and elasticity
- Are targeting pores and texture long term
- Want a more structural rejuvenation treatment
PDRN may be better if you:
- Have sensitive or irritated skin
- Need recovery after aesthetic procedures
- Struggle with redness or inflammation
- Want gentle skin healing and hydration
- Are looking for a lower-intensity regenerative treatment
Final thoughts
PN and PDRN are both effective regenerative skin treatments, but they serve different priorities. PN is generally the stronger option for long-term anti-aging, collagen stimulation, and structural skin improvement, making it ideal for patients with elasticity loss and visible aging changes. PDRN excels at healing, calming inflammation, and accelerating recovery after procedures, making it particularly useful for sensitive or recently treated skin. In Korean dermatology, many clinics combine PDRN for recovery with PN for long-term regeneration to achieve both healthy healing and durable rejuvenation.
