Science
Mechanism of Action
As a hydrophilic analog of alpha-tocopherol (Vitamin E), Trolox scavenges peroxyl and alkoxyl radicals in both aqueous and lipid cellular compartments. This dual-compartment action reduces intracellular Reactive Oxygen Species (ROS) levels and inhibits lipid peroxidation, thereby safeguarding skin cells, including fibroblasts, from oxidative damage.

The Formula
Formulation
Stability
Trolox, a weak acid with a pKa of 3.9, demonstrates significantly improved water solubility and optimal stability at neutral to alkaline pH, specifically within the 7.0 to 9.7 range. Efficacy may be compromised in highly acidic conditions.

Safety
Safety Profile
No specific safety assessments or opinions from CIR, SCCS, or FDA for cosmetic use of Trolox were found. It is crucial to note that at higher concentrations, specifically between 40-160 µM in cellular studies, Trolox exhibited dose-dependent prooxidant effects, increasing intracellular Reactive Oxygen Species (ROS) basal levels.
