PDRN vs Licorice Root Extract: Which Is Better for Your Skin?
Compare PDRN and Licorice Root Extract 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 Licorice Root Extract: Glabridin inhibits tyrosinase, anti-inflammatory |
|---|---|
| Primary Use | PDRN: Skin regeneration, wound healing, anti-aging Licorice Root Extract: Brightening, reducing redness, hyperpigmentation |
| Molecular Weight | PDRN: 50-1500 kDa (optimized for skin penetration) Licorice Root Extract: 324 Da (Glabridin) |
| Penetration | PDRN: Injectable or enhanced topical delivery Licorice Root Extract: Good |
| Irritation Potential | PDRN: Very Low Licorice Root Extract: Very Low |
How Does Licorice Root Extract Work?
Licorice Root Extract is a brightening agent that glabridin inhibits tyrosinase, anti-inflammatory. It's primarily used for brightening, reducing redness, hyperpigmentation.
With a molecular weight of 324 Da (Glabridin), Licorice Root Extract has good penetration capabilities. The irritation potential is very low, 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.
