Science
Mechanism of Action
Operating at a fundamental cellular level, oxosuccinic acid engages in critical biochemical processes, including the citric acid cycle. Its observed biological roles encompass enhancing mitochondrial function, effectively neutralizing reactive oxygen species (ROS), and exhibiting geroprotective properties, collectively pointing towards a profound influence on maintaining skin health and resilience.

Stability
Oxosuccinic acid exhibits pKa values at 2.22, 3.89, and 13.03, indicating its acidic characteristics and ionization states. For maintaining its active, acidic form and ensuring optimal bioavailability in cosmetic formulations, a pH around 3.5 is generally recommended for similar cosmetic acids. Chemical stability is best preserved in powder form when stored at -20°C for up to 3 years. Solutions should be stored at -80°C for 6 months or -20°C for 1 month.
Safety
Safety Profile
Oxosuccinic acid lacks specific safety assessments by key cosmetic regulatory bodies such as the Cosmetic Ingredient Review (CIR) Expert Panel and the Scientific Committee on Consumer Safety (SCCS). The U.S. FDA does not mandate pre-market approval for cosmetic ingredients; manufacturers bear responsibility for product safety. Notably, some suppliers label this ingredient 'for research use only' and advise against human consumption or direct sales to patients.

Verdict
While oxosuccinic acid presents interesting mechanistic potential for cellular skin health, the current lack of dedicated cosmetic safety assessments and clinical efficacy data necessitates caution and further research for its inclusion in precision skincare.
