What Is Tourmaline?
Tourmaline is a crystalline mineral compound used in skincare formulations primarily as a viscosity controlling agent. It works to help maintain the texture and consistency of creams, lotions and serums, ensuring products remain stable and easy to apply.
In cosmetic formulations, tourmaline functions as a thickening and stabilising ingredient rather than as an active treatment component. It appears in approximately 0.1% of skincare products on the market.
How It Works
Tourmaline adjusts the viscosity (thickness) of formulations, acting as a suspending and stabilising agent. This allows skincare products to maintain their intended texture—whether that's a lightweight gel or a richer cream—and prevents separation or breakdown of ingredients over time.
Clinical Evidence & References
Tourmaline's role in skincare is primarily functional rather than therapeutic. Published research on tourmaline as a skincare ingredient is limited, and most evidence concerns its use as a formulation tool rather than a direct benefit to skin health or appearance.

How to Use
Tourmaline-containing products should be used according to the specific product instructions, as this ingredient's role is to support the overall formulation rather than determine application frequency or method.
