            "articleBody": "Different piercing materials and their properties:\n\n**Titanium G23**\n\n- **Material composition**Titanium alloy Ti-6Al-4V ELI (titanium with 6% aluminum and 4% vanadium, Extra Low Interstitials)\n- **Advantages**Highly biocompatible, hypoallergenic, lightweight, and corrosion-resistant. Nickel-free and well-tolerated.\n- **Disadvantages**Higher price compared to surgical steel.\n- **Suitability**Ideal for first-time piercings, very sensitive skin, and for everyday wear.\n\n**Titanium ASTM F-136**\n\n- **Material composition**Ti-6Al-4V ELI titanium alloy (equivalent to G23 titanium) in accordance with the ASTM F-136 Implant Standard\n- **Advantages**High, certified purity; material quality that meets industry standards; maximally biocompatible; hypoallergenic; lightweight and corrosion-resistant. Complies with medical implant standards.\n- **Disadvantages**Higher price compared to surgical steel.\n- **Suitability**Ideal for first-time piercings, very sensitive skin, and for everyday wear.\n\n**316L surgical steel**\n\n- **Material composition**Iron (main component), chromium and nickel.\n- **Advantages**Robust, cost-effective, widely used.\n- **Disadvantages**Contains nickel, may cause allergies.\n- **Suitability**Suitable for healed piercings, not for fresh ones.\n\n**Brass**\n\n- **Material composition**Alloy of copper and zinc.\n- **Advantages**Malleable, cost-effective, gold-like appearance.\n- **Disadvantages**Contains nickel, can cause allergies. Tends to oxidize as it reacts with moisture and oxygen (similar to sterling silver). This can result in a dark patina (discoloration) on the piercing jewelry.\n- **Suitability**Suitable for healed piercings, not for fresh ones. More suitable as decorative piercing jewelry than for permanent piercing jewelry.\n\n**Sterling silver 925**\n\n- **Material composition**92.5% pure silver and 7.5% other metals (mostly copper)\n- **Advantages**Lighter than titanium or surgical steel, cheaper than 14k/18k gold, high-quality and shiny silver finish\n- **Disadvantages**Contains nickel, can cause allergies. Tends to oxidize as it reacts with moisture, oxygen and sulphur. This can result in a dark patina (discoloration) on the piercing jewelry.\n- **Suitability**Suitable for healed piercings, not for fresh ones.\n\n**Gold (14K/18K)**\n\n- **Material composition**Gold (main component), silver, copper and zinc.\n- **Advantages**Noble material, durable, well tolerated.\n- **Disadvantages**High-priced, should not be gold-plated (no gold-plated metal). Otherwise it may flake off.\n- **Suitability**Safe for healed piercings, ideal for jewelry lovers.\n\n**Bioflex / Bioplast**\n\n- **Material composition**PTFE (polytetrafluoroethylene)\n- **Advantages**Flexible, biocompatible, nickel-free, non-metallic (ideal for MRI/CT).\n- **Disadvantages**May wear out or discolor more quickly.\n- **Suitability**Good for sensitive skin, healing phases, tooth protection for tongue piercings, pregnancy piercings and medical applications.\n\n**Acrylic**\n\n- **Material composition**PMMA (polymethyl methacrylate)\n- **Advantages**Lightweight, inexpensive, metal-free and nickel-free.\n- **Disadvantages**May break on impact, not suitable for fresh piercings.\n- **Suitability**Only for short wearing times or stretched piercings.\n\n**Organic (wood, horn and stone)**\n\n- **Material composition**Natural materials (wood, horn, stone)\n- **Advantages**Natural, breathable, lightweight.\n- **Disadvantages**Sensitive to moisture, cannot be sterilized.\n- **Suitability**Only for healed, stretched piercings, not for fresh piercings.\n\n**Conclusion**\n\nTitanium or Bioflex are ideal for initial piercings. All other materials are suitable for healed piercings. The choice of the right material depends on compatibility, wearing comfort and personal style.",
