What Is Aluminum Glycinate?
Aluminium glycinate is a salt formed from aluminium and the amino acid glycine. It functions as an astringent and pH buffer in skincare formulations, meaning it helps tighten the appearance of pores and maintain the stability of product pH levels.
This ingredient is used primarily in topical skincare products where consistent pH and mild astringent properties are beneficial. It is distinct from aluminium chlorohydrate (commonly used in antiperspirants) and has a different chemical structure designed for facial skincare applications.
How It Works
Aluminium glycinate works as an astringent by causing mild protein coagulation on the skin's surface, which creates a slight tightening sensation. This can temporarily refine the appearance of pores and make skin feel firmer.
As a buffer, it neutralises acids or bases within a formulation, helping to maintain the optimal pH range for both product stability and skin compatibility. This ensures that skincare products remain effective and well-tolerated over time.
Clinical Evidence & References
Evidence specific to aluminium glycinate in skincare is limited. Available research suggests that aluminium glycinate compounds have low sensitising potential when applied topically, based on animal studies examining delayed skin reactivity.
The ingredient's use in hydrogel delivery systems indicates it can be incorporated safely into topical formulations. However, more human clinical studies would strengthen our understanding of its specific efficacy for pore appearance and skin tightening in real-world use.
How to Use
Aluminium glycinate is typically used as a supporting ingredient within formulations rather than as a standalone treatment. It is most effective when combined with other actives targeting specific skin concerns. No special application technique is needed; use products containing this ingredient as directed on the label.
