Authenticity testing is essential for verifying the genuineness of products, claims, and information in an era where counterfeiting and misinformation are prevalent. By ensuring that products are true to their claimed origins, qualities, and compositions, authenticity testing safeguards consumer trust, protects brand integrity, and upholds market fairness. In sectors such as cosmetics, personal care and formulations, authenticity testing helps ensure safety and maintains high standards, ultimately fostering transparency and reliability across industries.
