Quick Comparison

Mechanism PDRN: DNA fragment signaling activates adenosine A2A receptors for cellular regeneration
Citric Acid: AHA that also chelates metals and adjusts pH
Primary Use PDRN: Skin regeneration, wound healing, anti-aging
Citric Acid: Exfoliation, pH adjustment, brightening
Molecular Weight PDRN: 50-1500 kDa (optimized for skin penetration)
Citric Acid: 192.1 Da
Penetration PDRN: Injectable or enhanced topical delivery
Citric Acid: Moderate
Irritation Potential PDRN: Very Low
Citric Acid: Low to Moderate

How Does Citric Acid Work?

Citric Acid is a exfoliant that aha that also chelates metals and adjusts ph. It's primarily used for exfoliation, ph adjustment, brightening.

With a molecular weight of 192.1 Da, Citric Acid has moderate penetration capabilities. The irritation potential is low to moderate, making it best suited for those who can tolerate active ingredients.

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.
