Biotechnology

Sodium DNA

A skin-conditioning biomaterial used in advanced cosmetic formulations to support a revitalized appearance.

Key Benefits

  • Conditions and smooths the skin surface
  • Supports a hydrated, supple feel
  • Complements revitalizing formulas
  • Provides a biotechnology-derived polymer
  • Supports a refreshed-looking complexion

How It Works

As a negatively charged biopolymer, Sodium DNA can bind water and contribute to a conditioning film in a topical formula. Defined fragmented DNA preparations are also studied for signaling pathways related to extracellular-matrix homeostasis, but activity depends strongly on fragment length, purity, source and delivery.

Intact skin is a substantial penetration barrier for large nucleotide polymers. Research on a specific medium-length topical PDRN with demonstrated delivery does not prove equivalent penetration or biological effects for an unspecified Sodium DNA cosmetic ingredient.

Ingredient Details

INCI Name: Sodium DNA

Ingredient Type: Biotechnology

Best For

Dehydrated or dull-looking skin · Advanced biotechnology formulas · Preventive age-support routines · Skin needing surface conditioning

Research

What It Is

A sodium-salt DNA biopolymer used in cosmetics; its origin and chain-length distribution vary and are not fully defined by the INCI name alone.

What It Does

Conditions the skin surface and supports a hydrated, supple and revitalized appearance, with advanced biological claims dependent on source and molecular specification.

Sodium DNA FAQs

Common questions about this ingredient in skincare.

What is Sodium DNA?
It is the sodium salt of DNA used as a cosmetic skin-conditioning polymer. Its source and fragment size depend on the supplier.
Is Sodium DNA the same as PDRN?
Not necessarily. PDRN describes defined mixtures of deoxyribonucleotide chains, while the INCI name Sodium DNA alone does not establish molecular-length specifications or equivalence.
Is it the same as injectable PDRN?
No. A topical cosmetic ingredient differs from sterile injectable medical products in delivery, regulation, dose and intended use.
Does it repair my DNA?
No. Sodium DNA is not a DNA-repair enzyme and should not be claimed to repair genetic damage in skin cells.
Is it vegan?
The source may be marine-derived or biotechnology-derived depending on the supplier. Check the finished product or raw-material documentation for provenance.
What evidence supports topical use?
Emerging research supports certain specifically characterized topical PDRN systems, but evidence cannot be generalized to every Sodium DNA material or formula.
