Science
Mechanism of Action
It operates through hydrolysis, releasing fluoride ions that facilitate the reorganization of mineral structures. In skincare applications, its crystalline form provides mild physical abrasion to remove devitalized cells, while its chemical structure assists in maintaining the alkaline-acid equilibrium of a formulation.
Research
Clinical Evidence
High confidence0.15%
Key findings
- 01 Clinical evaluation demonstrated that a 1.14% concentration significantly minimizes mineral loss and promotes enamel remineralization over a 24-month period.
- 02 The SCCS has validated 0.15% (calculated as total Fluoride) as the benchmark for safe and effective topical application.
Transparency
Dusting Analysis
Because it is often associated with oral care efficacy at 0.15%, skincare products may include it at negligible levels for marketing claims without providing functional exfoliation or buffering benefits.
The Formula
Formulation
Stability
Highly stable across a wide pH range (2-13), though it is most effective for ion release at pH 8.0. Extreme acidity (pH < 2.0) must be avoided to prevent the formation of corrosive hydrofluoric acid.
Synergies
- Calcium carbonate
- Phosphate buffers
Conflicts
- Strong acids
- Glass packaging
- Strong oxidizing agents
- Multivalent metal ions
Safety
Safety Profile
Regulatory limits are strictly enforced at 0.15% total Fluoride in the EU and ASEAN regions. Avoid contact with silica-based glass in liquid form.
