Quick Comparison

Mechanism PDRN: DNA fragment signaling activates adenosine A2A receptors for cellular regeneration
Palmitoyl Tetrapeptide-7: Reduces IL-6 production to decrease inflammation
Primary Use PDRN: Skin regeneration, wound healing, anti-aging
Palmitoyl Tetrapeptide-7: Anti-inflammatory, anti-aging
Molecular Weight PDRN: 50-1500 kDa (optimized for skin penetration)
Palmitoyl Tetrapeptide-7: 637.9 Da
Penetration PDRN: Injectable or enhanced topical delivery
Palmitoyl Tetrapeptide-7: Good
Irritation Potential PDRN: Very Low
Palmitoyl Tetrapeptide-7: None

How Does Palmitoyl Tetrapeptide-7 Work?

Palmitoyl Tetrapeptide-7 is a anti-inflammatory peptide that reduces il-6 production to decrease inflammation. It's primarily used for anti-inflammatory, anti-aging.

With a molecular weight of 637.9 Da, Palmitoyl Tetrapeptide-7 has good 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.
