PDRN vs SH-Oligopeptide-1 (EGF): Which Is Better for Your Skin?
Compare PDRN and SH-Oligopeptide-1 (EGF) for skincare. Learn the differences in mechanism, results, and when to use each for optimal skin health.
Quick Comparison
| Mechanism | PDRN: DNA fragment signaling activates adenosine A2A receptors for cellular regeneration SH-Oligopeptide-1 (EGF): Signals epidermal cell proliferation |
|---|---|
| Primary Use | PDRN: Skin regeneration, wound healing, anti-aging SH-Oligopeptide-1 (EGF): Wound healing, anti-aging |
| Molecular Weight | PDRN: 50-1500 kDa (optimized for skin penetration) SH-Oligopeptide-1 (EGF): 6.2 kDa |
| Penetration | PDRN: Injectable or enhanced topical delivery SH-Oligopeptide-1 (EGF): Limited topically |
| Irritation Potential | PDRN: Very Low SH-Oligopeptide-1 (EGF): None |
How Does SH-Oligopeptide-1 (EGF) Work?
SH-Oligopeptide-1 (EGF) is a epidermal growth factor that signals epidermal cell proliferation. It's primarily used for wound healing, anti-aging.
With a molecular weight of 6.2 kDa, SH-Oligopeptide-1 (EGF) has limited topically penetration capabilities. The irritation potential is none, making it suitable for most skin types.
How Does PDRN Compare?
PDRN (Polydeoxyribonucleotide) works through a fundamentally different mechanism. Derived from salmon DNA, PDRN provides nucleotide fragments that activate the adenosine A2A receptor pathway, triggering genuine cellular regeneration and tissue repair.

Frequently Asked Questions
What is the main difference between PDRN and SH-Oligopeptide-1 (EGF)?
PDRN works through DNA fragment signaling to activate cellular repair and regeneration at a fundamental level. SH-Oligopeptide-1 (EGF) signals epidermal cell proliferation. While both can benefit skin health, they work through completely different pathways.
Can I use PDRN and SH-Oligopeptide-1 (EGF) in the same routine?
