PDRN vs TCA Peel (Trichloroacetic Acid): Which Is Better for Your Skin?
Compare PDRN and TCA Peel (Trichloroacetic Acid) 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 TCA Peel (Trichloroacetic Acid): Medium-depth peel causing controlled chemical injury |
|---|---|
| Primary Use | PDRN: Skin regeneration, wound healing, anti-aging TCA Peel (Trichloroacetic Acid): Moderate wrinkles, scars, pigmentation |
| Molecular Weight | PDRN: 50-1500 kDa (optimized for skin penetration) TCA Peel (Trichloroacetic Acid): 163.4 Da |
| Penetration | PDRN: Injectable or enhanced topical delivery TCA Peel (Trichloroacetic Acid): Medium depth |
| Irritation Potential | PDRN: Very Low TCA Peel (Trichloroacetic Acid): High - significant peeling |
How Does TCA Peel (Trichloroacetic Acid) Work?
TCA Peel (Trichloroacetic Acid) is a professional treatment that medium-depth peel causing controlled chemical injury. It's primarily used for moderate wrinkles, scars, pigmentation.
With a molecular weight of 163.4 Da, TCA Peel (Trichloroacetic Acid) has medium depth penetration capabilities. The irritation potential is high - significant peeling, 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.
Dramatically faster healing
