Polynucleotide (PN)

Polynucleotide (PN)
Polynucleotide (PN) is a biopolymer consisting of a long chain of nucleotide units. As the fundamental building block of genetic material (DNA and RNA), PN extracted for commercial use is a purified, naturally occurring linear polymer. It serves as an advanced ingredient for tissue regeneration and anti-aging treatments.

Key Applications and Benefits
Scaffolding and Volumizing: Due to its viscosity and ability to bind water, PN acts as a structural scaffold within the tissue. This provides immediate hydration and adds volume, improving skin firmness and elasticity.

Cellular Regeneration: PN provides the necessary nucleotide precursors for cell repair and DNA synthesis. This accelerates the proliferation of fibroblasts, which are responsible for producing collagen and elastin, thereby promoting genuine tissue healing.

Targeted Repair: When injected, PN promotes localized tissue restructuring. This makes it effective for improving the appearance of scars, deep wrinkles, and areas requiring delicate regeneration (e.g., undereye area and neck).

Safety Profile: PN is known for its excellent biocompatibility, as it is a natural component of the body. When sourced and purified correctly (often from fish DNA), it minimizes the risk of adverse immune reactions.

Mechanism Differentiation
While chemically similar to PDRN (Polydeoxyribonucleotide), PN typically refers to longer, more intact chains of nucleotides, which are optimized for their viscoelastic and scaffolding properties in injectable treatments, complementing the cellular repair functions.
