Science
Mechanism of Action
It functions via the 'Bohr Effect': as carbonic acid lowers the localized pH of the skin, it signals hemoglobin to release oxygen directly into the tissues. This process induces rapid vasodilation and boosts microcirculation, providing a surge of metabolic energy to skin cells while simultaneously stimulating ceramide production to reinforce the lipid barrier.

Key findings
- 01 A 4-week study involving thrice-weekly applications showed a 27% increase in skin radiance and a 19% improvement in microcirculation.
- 02 Research indicates that concentrations between 350-1500 mg/L of dissolved CO2 effectively stimulate epidermal ceramide synthesis and reduce transepidermal water loss (TEWL).

Dusting Analysis
Often marketed in 'bubble masks' at negligible concentrations for sensory effect only. True efficacy requires specific delivery systems to maintain the 350-1500 mg/L threshold needed to trigger the Bohr Effect.
The Formula
Formulation
Stability
Highly volatile and prone to rapid degassing. Effective delivery requires pressurized canisters or in-situ generation via dual-chamber carboxy systems to prevent the acid from decomposing back into CO2 gas.
Synergies
- Ceramides
- Hyaluronic Acid
- Vasodilators
Conflicts
- High pH environments
