Key Takeaways
- Unintentional Impurities: Nickel is never an added ingredient, but it can occur as a trace impurity from raw minerals and stainless steel production mills.
- The Testing Difference: While nickel is legally restricted, “Nickel Tested” means a brand verifies that trace levels are virtually undetectable (below 0.00001%).
- NZ Skin Barrier: Our high UV and coastal winds can sensitize the skin, making these microscopic traces a common trigger for stinging or redness.
- Foundation Focus: Choosing a Nickel Tested base is essential because foundation covers the largest area of your face for the longest time.
Have you ever applied a beautiful new foundation, only to find your skin tingling or your eyes feeling itchy and watery by lunchtime? For many New Zealanders, this isn’t necessarily a reaction to the makeup itself, but to microscopic “impurities” that sneak into the production process. Understanding the “Nickel Tested” badge is the key to finally wearing makeup comfortably again.
How does Nickel end up in makeup if it’s prohibited?
Nickel is prohibited as an intentional ingredient in modern cosmetics, but it remains a persistent “technical impurity” that enters formulas through raw minerals and manufacturing machinery.
The vibrant, earthy colours in organic foundations and powders come from iron oxides—minerals naturally mined from the earth. Because nickel is a natural element in the earth’s crust, it is often found in small amounts within these raw pigments. Additionally, the industrial process of mixing and grinding these minerals involves high-grade stainless steel mills. Over time, these machines can shed microscopic traces of nickel into the final formula.
While the law prohibits adding nickel, most standard brands do not perform the additional laboratory analysis to see what the “accidental” levels are. When puroBIO labels a product as Nickel Tested, it means we have analysed the finished batch to ensure these unavoidable traces are kept below 0.00001%. This is the scientific threshold for safety for those who experience skin stinging or contact dermatitis.
Why is this critical for the New Zealand environment?
Our unique climate, with its high UV levels and coastal winds, can weaken the skin’s natural barrier, making us more susceptible to reacting to even the smallest heavy metal traces.
In a high-sensitization environment like New Zealand, a compromised skin barrier allows microscopic impurities to penetrate more easily, triggering an immune response. This often manifests as that “stinging” feeling when you apply foundation, or dry, peeling lips that many people mistakenly blame on the wind.
By choosing a “Nickel Tested” routine, you are effectively closing the door on these hidden triggers. This level of purity is especially important for the products you wear over your entire face, such as foundation and BB cream. With the Italian standard of batch-testing, you are ensuring that your professional look doesn’t come at the cost of your comfort or long-term skin health.
Experience The Nickel-Tested Difference
We prioritise testing for our most pigment-rich formulas to ensure they are safe for reactive skin and eyes:
- Sublime Foundation: High-performance coverage that respects your skin’s natural barrier.
- Double Dream Mascara: Pure volume with strictly monitored nickel levels for sensitive eyes.
Can organic makeup truly be professional-grade?
Yes. Modern organic technology allows for intense pigment payoff and longevity without relying on the unrefined minerals that often carry high metal loads.
There is a common misconception that “safe” makeup must be sheer or barely-there. By sourcing premium, highly-refined mineral pigments from Italy, puroBIO creates deep, opaque colours that meet the standards of professional makeup artists. You no longer have to choose between high-fashion results and scientific safety.
Nickel Testing FAQ
Q: If nickel is prohibited, why do I still react to some makeup?
A: The prohibition applies to the intentional addition of nickel. Microscopic “trace” amounts from manufacturing machinery and raw minerals are often still present but go untested in standard brands.
Q: Are all puroBIO products tested for nickel?
A: We prioritise Nickel Testing for our makeup range, as these products contain the mineral pigments where trace impurities are most likely to occur. You can identify these by the “Nickel Tested” logo on the packaging. Products without these minerals, such as our hair care or brushes, typically do not require this specific test.
Q: Is “Nickel Free” better than “Nickel Tested”?
A: “Nickel Free” is technically impossible because nickel is a natural element found in the earth’s crust. “Nickel Tested” is the more honest and scientifically accurate term used by professional brands.
