Mechanism of Action
As a disodium salt of succinic acid, an intermediate in the tricarboxylic acid cycle, disodium succinate's parent compound can induce pseudohypoxia, a state potentially beneficial for maintaining cellular stemness and exhibiting geroprotective qualities in human dermal fibroblasts, particularly under high oxygen conditions. Furthermore, it is suggested to alleviate irritation, reduce the incidence of breakouts, and bolster the skin's defense against oxidative damage. Extracellular succinate can also act as a cellular signaling molecule by binding to and activating the GPR91 (SUCNR1) receptor, influencing diverse cellular pathways.

The Formula
Formulation
Stability
Disodium succinate demonstrates high solubility in water but is insoluble in organic solvents such as ethanol. As the salt of a weak diprotic acid, it functions effectively as a buffer within a slightly acidic pH range of 4.2 to 5.6, which is well-aligned with the skin's natural pH and typical skincare product formulations.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not issued a specific safety assessment. However, the U.S. FDA deems it safe for general or limited food use. Both the EWG Skin Deep database and SkinSAFE indicate low concerns for toxicity, allergies, and irritation, classifying it as 'Irritant Free' and suitable for sensitive skin.
