Science
Mechanism of Action
Operating at a fundamental cellular level, Sodium DNA delivers essential purine and pyrimidine bases, crucial for cell health. It enters cells via pinocytosis, integrating into cellular DNA metabolism and nucleic acid synthesis, particularly beneficial for stressed cells such as aged keratinocytes and fibroblasts. This stimulates new skin cell production and collagen synthesis, supporting tissue repair and improving skin firmness. Furthermore, Sodium DNA engages epidermal and dermal cells by activating toll-like receptors (TLR-9), which consequently upregulates vital growth factors like TGF-β, VEGF, and EGF, profoundly boosting fibroblast activity and the creation of new collagen. Its multifaceted action also includes robust hydrating, antioxidant, and anti-inflammatory properties that calm irritation and promote an even skin tone.

Key findings
- 01 Clinical application of 0.36% SH-DNA twice daily demonstrated a 15-20% improvement in skin elasticity and enhanced skin nutrition, with no reported irritation or allergic reactions.
- 02 Utilizing pure Sodium DNA powder, clinical trials indicated a 135% greater reduction in wrinkle depth compared to placebo over eight weeks, alongside a 26% increase in skin elasticity.
- 03 Another study observed a significant increase in skin hydration levels, boosting them from an initial 15% to 60% post-treatment with Sodium DNA.

Dusting Analysis
There is no available data to suggest that SH-DNA is commonly "dusted" in formulations, meaning its concentration is unlikely to be misleadingly low to meet marketing claims. The ingredient demonstrates efficacy at specific, documented concentrations.
The Formula
Formulation
Stability
SH-DNA maintains stability within a pH range of 5.0 to 9.0. Acidity below pH 5.0 can lead to depurination and phosphodiester bond degradation, while alkalinity above pH 9.0 can cause alkaline denaturation. For long-term stability and minimal base loss, storage at approximately pH 8.0 is recommended.
Conflicts
- Variations in salt concentration outside the 0.1-0.9% w/w range may compromise the integrity of native DNA sodium salt or complicate formulation.
- To maximize topical absorption and effectiveness, utilizing penetration enhancement methods such as laser peels, chemical peels, or microneedling may be necessary.
Safety
Safety Profile
Sodium DNA is generally considered safe for topical cosmetic use, exhibiting a low potential for irritation and allergenicity in clinical assessments. No significant adverse effects have been documented, and its application aligns with existing cosmetic regulations. However, individuals with sensitive skin or known allergies should perform patch testing. Specific data regarding its safety during pregnancy and breastfeeding is currently insufficient, thus professional medical advice is advised for these populations.
