Quick Comparison

Mechanism PDRN: DNA fragment signaling activates adenosine A2A receptors for cellular regeneration
Glycine: Most abundant amino acid in collagen
Primary Use PDRN: Skin regeneration, wound healing, anti-aging
Glycine: Collagen support, wound healing
Molecular Weight PDRN: 50-1500 kDa (optimized for skin penetration)
Glycine: 75.1 Da
Penetration PDRN: Injectable or enhanced topical delivery
Glycine: Excellent
Irritation Potential PDRN: Very Low
Glycine: None

How Does Glycine Work?

Glycine is a collagen component that most abundant amino acid in collagen. It's primarily used for collagen support, wound healing.

With a molecular weight of 75.1 Da, Glycine has excellent 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.

Fundamental repair support

Glycine Best For

  • All skin types
  • Collagen needs

Glycine Not Ideal For

  • None

Can You Use PDRN and Glycine Together?

Primary collagen amino acid + PDRN

The Verdict

Essential amino acid pairing

Frequently Asked Questions

What is the main difference between PDRN and Glycine?

PDRN works through DNA fragment signaling to activate cellular repair and regeneration at a fundamental level. Glycine most abundant amino acid in collagen. While both can benefit skin health, they work through completely different pathways.

Can I use PDRN and Glycine in the same routine?

Primary collagen amino acid + PDRN

Which is better for anti-aging: PDRN or Glycine?

Fundamental repair support Essential amino acid pairing

Is PDRN or Glycine more irritating?

PDRN has very low irritation potential and is well-tolerated by most skin types. Glycine has none irritation potential. Both are generally well-tolerated.
