Ammonium Fluoride
INCI: AMMONIUM FLUORIDE
A fluoride compound primarily used in oral care and industrial applications
What Is Ammonium Fluoride?
Ammonium fluoride is an inorganic salt compound containing fluoride ions. It is commonly found in oral care products such as toothpastes and mouthwashes, where it serves as a source of bioavailable fluoride. The compound is also used in various industrial and laboratory applications.
In skincare formulations, ammonium fluoride appears infrequently and is not a primary active ingredient. Its inclusion in topical products is limited, and most cosmetic use centres on oral hygiene rather than facial skincare.
How It Works
Ammonium fluoride dissociates in aqueous solutions to release fluoride ions. In oral care products, these ions are absorbed by tooth enamel and help strengthen it against decay. The mechanism relies on fluoride's ability to remineralise tooth structure and inhibit bacterial acid production.
In topical skincare applications, the role of ammonium fluoride is less clearly defined, as fluoride's primary benefits are concentrated in dental health rather than skin treatment.
Clinical Evidence & References
The evidence for ammonium fluoride in skincare is limited. Most research on this ingredient focuses on its use in oral care and industrial chemistry rather than dermatological applications. Published studies examining its effects on skin health are sparse.
Some older research has examined ammonium fluoride's irritancy potential in animal models, with mixed findings on its capacity to cause irritation or pustulation. These studies do not provide reliable guidance for modern skincare use. Clinical evidence supporting its inclusion in facial skincare products remains unclear.

How to Use
Ammonium fluoride is not a common skincare ingredient, and products containing it are rare outside the oral care category. If present in a skincare formula, follow the manufacturer's instructions regarding application frequency and quantity. Given the limited dermatological research on this ingredient, introduce it cautiously and monitor your skin's response.
