Introduction: Understanding Harmful Substances in Piercing Jewelry
Piercing jewelry is a popular way to express individuality and style. However, choosing the right jewelry isn’t just about looks. It’s also about ensuring your health and safety. Many metals and materials used in jewelry can potentially cause irritation, allergic reactions, or more serious health issues if not carefully selected.
In this blog, we will dive into the harmful substances that may be found in piercing jewelry, why these materials can be problematic, and how Sensagem ensures the highest safety standards with our certified products.

1. Common Harmful Substances in Piercing Jewelry
While high-quality materials are commonly used in the manufacturing of piercing jewelry, some cheaper or non-certified jewelry can contain harmful substances. These materials can irritate the skin, cause allergic reactions, or even lead to long-term health problems. The most common harmful substances in piercing jewelry include:

1.1 Nickel
Nickel is one of the most common allergens in jewelry. It is a metal used in many alloys, especially in cheaper jewelry options. In fact, around 10-15% of the population is allergic to nickel, and exposure can cause itching, redness, and swelling at the piercing site.
Why Nickel is Harmful:
Nickel can cause dermatitis, a condition that results in skin irritation and rashes. Long-term exposure may also worsen the symptoms and lead to more severe allergic reactions. For this reason, it’s essential to choose jewelry made from nickel-free materials, particularly for sensitive areas like the nose and ears.

1.2 Lead
Lead is another toxic substance that may be present in low-quality jewelry. Lead can be absorbed through the skin and pose serious health risks, including damage to the nervous system, especially in children.
Why Lead is Harmful:
Lead exposure can cause a range of health issues, including developmental problems in children, high blood pressure, and even damage to organs. For this reason, lead should never be used in jewelry, especially in body jewelry that comes into direct contact with the skin.

1.3 Chromium
Chromium is a heavy metal commonly used in jewelry for its corrosion-resistant properties. While chromium itself isn’t always harmful, when it’s used in high amounts or isn’t properly processed, it can lead to allergic reactions and skin irritation.
Why Chromium is Harmful:
Some forms of chromium can be toxic to the skin and may lead to dermatitis or other allergic reactions. Chromium should always be used in its safe, processed form to ensure it doesn’t leach into the skin.

1.4 Cadmium
Cadmium is another toxic metal sometimes found in cheap jewelry. It is primarily used to make jewelry more durable and resistant to corrosion.
Why Cadmium is Harmful:
Cadmium is extremely toxic and can accumulate in the body over time. Long-term exposure to cadmium can lead to kidney damage, bone loss, and respiratory issues. Jewelry made from cadmium should be avoided, especially for piercings that are in direct contact with the skin.
2. Sensagem’s Commitment to Safe Materials
At Sensagem, we understand the importance of using safe materials for our piercing jewelry. That’s why we only use premium materials that have passed strict testing and are free from harmful substances.
2.1 Nickel-Free Materials
We prioritize the use of ASTM F136 titanium og 316L stainless steel, which are both hypoallergenic and nickel-free. These materials have been tested and certified to be safe for sensitive skin, reducing the risk of allergic reactions.
To learn more about the benefits of these materials, check out our article: ASTM F136 Titanium and 316L Stainless Steel: The Best Materials for Piercing Jewelry.
2.2 High-Quality Alloys
For customers who prefer gold jewelry, Sensagem offers 14K and 18K gold plated piercing jewelry. These gold pieces are carefully selected and processed to meet strict safety standards. We also avoid using any metals that could potentially contain harmful substances, ensuring that the jewelry is safe for long-term wear.
2.3 Biocompatibility Testing
In addition to using safe materials, we also conduct thorough biocompatibility testing on all our piercing jewelry. This testing ensures that each piece is not only safe for the body but also that it won’t cause irritation or rejection during the healing process. We believe in offering products that promote both style and health.
3. The Importance of Surface Finishing in Piercing Jewelry
Even if the metal used in your jewelry is safe, the surface finish plays a crucial role in its overall safety and comfort. A smooth, polished surface reduces the risk of irritation, while rough or poorly finished jewelry can cause discomfort and increase the risk of infection.
3.1 Mirror Polishing vs. Electro Polishing
We use two main types of polishing techniques at Sensagem:
•Mirror Polishing: This technique gives the jewelry a smooth, reflective finish, eliminating any rough edges or microscopic grooves. It provides a sleek, high-quality appearance and is particularly important for sensitive areas like the nose and lips. A mirror-polished surface minimizes friction and irritation, helping to prevent infections during the healing process.
•Electro Polishing: Electro polishing is an advanced method that removes microscopic debris and contaminants from the jewelry’s surface. This method also creates a smooth, shiny finish while enhancing the durability of the material. Electro-polished jewelry is often used for medical-grade piercings, as it ensures the highest level of purity and smoothness.
Both methods ensure that Sensagem jewelry is safe to wear and easy to clean, minimizing the risk of infection and promoting quicker healing times.

5. Material Testing and Manufacturing Process
5.1 Raw Material Procurement and Testing
At Sensagem, we begin by carefully selecting raw materials for our piercing jewelry. We only work with certified suppliers to ensure that every batch of materials meets strict safety and quality standards. Our titanium alloys, 316L stainless steel, and other materials undergo rigorous quality inspections to ensure that they are free from harmful substances, such as nickel, lead, and chromium, which can be harmful to the body.
Before any raw materials are used in production, they are subjected to chemical composition analysis and toxicity testing. This ensures that they meet international standards such as ISO 10993 and ASTM F136, guaranteeing their safety for use in body jewelry. This thorough process eliminates the risk of using substandard materials, which could pose health risks to the wearer.
5.2 Quality Control During the Manufacturing Process
Once the raw materials are sourced and tested, the manufacturing process begins. We employ advanced CNC precision machining techniques to create the base shape of every piece of jewelry. CNC machining ensures that each piece is produced with high accuracy and consistency, providing a smooth, polished finish.
After CNC machining, the jewelry undergoes laser cutting, a technique that allows us to cut intricate patterns and shapes with precision. This ensures that each piece of jewelry is crafted with the finest detail, and the edges are smooth, minimizing the risk of irritation to the skin.
The pieces are then polished using electrolytic polishing and mirror polishing techniques. This not only enhances the jewelry’s shine but also removes any micro-level impurities and defects, smoothing out rough surfaces and reducing the likelihood of skin irritation.
5.3 Finished Product Testing and Quality Verification
After production, every piece of jewelry undergoes a comprehensive set of tests to ensure it meets our stringent quality standards. This includes:
•Metal Composition Analysis: Every finished piece undergoes analysis to confirm that the metal content adheres to international certification standards. This ensures that the jewelry contains no harmful substances that could affect the wearer’s health.
•Surface Hardness and Corrosion Resistance Testing: We also conduct tests on the surface hardness and corrosion resistance of our jewelry to ensure that it can withstand wear and tear. This helps prevent discoloration, fading, and corrosion, which could compromise the jewelry’s appearance and safety.
•Dimensional Accuracy Testing: Each piece is checked for size accuracy to ensure it meets the specifications provided by the client. Our technical team ensures that each piece is precisely crafted to ensure a perfect fit and optimal comfort for the wearer.
