Science
Mechanism of Action
Upon contact with skin, concentrated sulfuric acid instigates a vigorous exothermic reaction with epidermal water and organic constituents like fats and tissues. This leads to immediate and severe chemical and thermal burns, profound dehydration, tissue coagulation, and ultimately, necrosis. This mechanism is indicative of extreme harm, not therapeutic action.

Dusting Analysis
Sulfuric acid is not typically 'dusted' as a beneficial active ingredient due to its highly corrosive nature and lack of skincare efficacy. Its presence in cosmetic products is strictly as a pH adjuster in extremely low, neutralized concentrations, or as an impurity.
The Formula
Formulation
Stability
Stable indefinitely at room temperature when stored in sealed, vented containers. Dilution with water is a strongly exothermic process, requiring concentrated acid to be added slowly to water to prevent boiling and spraying.

- Organic materials
Safety
Safety Profile
Sulfuric acid is severely corrosive, causing immediate skin burns, eye damage, and permanent scarring. It is classified as a Group 1 carcinogen by the IARC and listed under California's Proposition 65. EWG deems it 'unacceptable' due to high cancer concerns. Direct topical application for skincare is unequivocally unsafe, with no safe concentrations for beneficial use.
