Science
Mechanism of Action
It functions as a universal solvent that facilitates the transport of nutrients via transmembrane proteins called Aquaporins (specifically AQP3). Water is vital for activating the proteolytic enzymes responsible for desquamation, ensuring the natural shedding of dead skin cells and maintaining the stratum corneum's pliability.
Research
Clinical Evidence
High confidence60%
Key findings
- 01 The stratum corneum requires a minimum 10% water concentration to maintain essential enzymatic activity for desquamation and prevent skin rigidity.
- 02 Most high-performance aqueous formulations utilize water at concentrations between 60% and 95% to ensure the efficient dispersion of active ingredients.

Dusting Analysis
As the base solvent for most products, water is rarely 'dusted'; however, if a water-based product contains less than 10% water in the outermost skin layers, the skin's natural exfoliation processes may become impaired.
The Formula
Formulation
Stability
Utilized in deionized or demineralized form to prevent mineral-induced destabilization. While chemically stable, it requires robust preservation to prevent rapid microbial proliferation.
Synergies
- Humectants (Glycerin, Hyaluronic Acid)
- Water-soluble vitamins
- Aquaporin-stimulating actives
Conflicts
- Pure L-Ascorbic Acid (oxidation risk)
- Anhydrous systems
- Water-sensitive peptide chains
- High-viscosity lipophilic oils without emulsifiers
Safety
Safety Profile
Universally recognized as safe (GRAS) and non-irritating, provided the water is purified to cosmetic standards.
