Science
Mechanism of Action
SODIUM DNA/RNA operates at a cellular level by enhancing the skin's natural barrier, thereby improving moisture retention and bolstering defense against environmental aggressors, leading to improved skin texture and hydration. It actively stimulates the proliferation of keratinocytes and fibroblasts, boosting cell vitality, skin thickness, and elasticity, which collectively contributes to a noticeable anti-aging effect and enhanced skin regeneration. The ingredient also demonstrates anti-inflammatory properties, soothes irritation, and supports collagen synthesis. Furthermore, it stimulates crucial growth factors, optimizes microcirculation, and inhibits melanin production for a more uniform and radiant complexion. Its antioxidant action neutralizes free radicals, safeguarding skin cells from oxidative stress, while also promoting cellular repair and wound healing. These effects are facilitated by DNA fragments, which serve as essential purine and pyrimidine base donors, capable of crossing cell membranes via pinocytosis, aided by sodium ions. Sodium RNA specifically contributes to melanin suppression by inhibiting the MITF gene and may help reduce cellulite through angiotensin-converting enzyme downregulation.

Key findings
- 01 Native DNA sodium salt is effectively utilized in topical pharmaceutical compositions within a concentration range of 0.1% to 4% by weight, with 0.1% to 2.5% being particularly preferred for optimal performance.
- 02 Purified fragments of Sodium DNA (PDRN) are incorporated into commercial skincare products at concentrations varying from 0.05% in serums to 10% in more intensive serums, 3% in ampoules, and 1% in serum/body treatments, indicating a broad spectrum of clinically relevant dosages.
- 03 A 0.12% sodium DNA formulation has been shown to modulate cell viability and reduce metabolic stress in specific biological contexts, suggesting efficacy at relatively low concentrations.

Dusting Analysis
There is no available data to suggest that SODIUM DNA/RNA is commonly 'dusted' at sub-efficacious percentages. The established clinical efficacy data supports usage within specific concentration ranges for optimal results.
The Formula
Formulation
Stability
SODIUM DNA/RNA maintains stability within a neutral pH range of 5 to 9. Stability can extend up to pH 9.0, even at elevated temperatures (e.g., 40°C). However, environments below pH 5 risk depurination, while those above pH 9 may induce alkaline denaturation. Given its high molecular weight and hydrophilic nature, effective cell penetration and protection from degradation necessitate high-quality formulations that incorporate suitable drug delivery systems.
Conflicts
- High concentrations of cationic salts (e.g., sodium acetate, ammonium acetate, sodium chloride, lithium chloride)
- Ethanol and Isopropanol (due to their role in precipitation)
- Highly acidic pH (below 5)
- Highly alkaline pH (above 9)
Safety
Safety Profile
SODIUM DNA/RNA is broadly considered safe for topical use in cosmetic formulations, exhibiting low potential for irritation and allergenicity in clinical assessments with no significant adverse effects reported. While specific CIR or SCCS reviews for this combined ingredient are not available, its general safety is acknowledged, and use complies with cosmetic regulations in major markets. Patch testing is recommended for individuals with highly sensitive skin or known allergies.
