Science
Mechanism of Action
Sodium RNA operates primarily as a sophisticated skin conditioning agent. It strengthens the epidermal barrier, which is crucial for moisture retention and defense against external stressors. Its anti-aging actions are theorized to include the downregulation of elastase, an enzyme responsible for elastin degradation, thereby preserving skin firmness and structure. Furthermore, Sodium RNA is suggested to mitigate hyperpigmentation by inhibiting the MITF gene, which in turn suppresses melanin production. It may also enhance microcirculation through the downregulation of the angiotensin converting enzyme, potentially addressing concerns like cellulite. Beyond these specific actions, it contributes antioxidant properties, promotes cellular energy metabolism via mitochondrial activation, reduces irritation, and accelerates skin regeneration by supporting new cell proliferation.

Key findings
- 01 Enhances skin's natural barrier function, promoting softer, smoother, and more hydrated skin while providing protection against environmental stressors, particularly beneficial for dry or sensitive skin.
- 02 May improve visible signs of aging by downregulating elastase, an enzyme that breaks down elastin fibers, potentially leading to a 'plumped look'.
- 03 Suggested to reduce the appearance of melasma by inhibiting the MITF gene, thereby suppressing melanin production.
- 04 Thought to aid in reducing the appearance of cellulite through improved microcirculation by downregulating the angiotensin converting enzyme.
- 05 Accelerates skin regeneration by fostering new skin cell production, vital for maintaining a youthful complexion and repairing damaged skin.
- 06 Stimulates collagen synthesis, contributing to firmer, smoother skin and improved elasticity, which helps to minimize fine lines and sagging.
- 07 Significantly improves the skin's moisture retention, resulting in a plump, radiant, and hydrated appearance.

The Formula
Formulation
Stability
RNA is susceptible to hydrolysis at extreme pH levels. Optimal stability for general RNA storage often occurs in a slightly acidic range (pH 5.5–6.5), while specific oligonucleotides have been adjusted to pH 7.0 for stability. Effective delivery through the skin barrier typically necessitates advanced formulation techniques such as liposomal encapsulation or co-formulation with small proteins or peptides. Enhanced solubility variants, like RNA-Na(W), are available to facilitate higher concentration formulations.
Safety
Safety Profile
Neither the Cosmetic Ingredient Review (CIR) Expert Panel nor the Scientific Committee on Consumer Safety (SCCS) has published specific safety assessments for Sodium RNA. The FDA status for Sodium RNA in cosmetics is not yet detailed. Adverse reactions are generally considered uncommon, with EWG Skin Deep rating it with low concerns across multiple categories, citing fair data availability. However, due to its relatively recent introduction, usage levels are not firmly established, and its overall safety profile is not fully understood. A patch test is advisable.
