Efficacy testing is a critical process that ensures the safety, reliability, and performance of products across various sectors, including pharmaceuticals, cosmetics, personal care, and healthcare. This scientific assessment verifies whether a product or formulation performs as intended, delivers its promised benefits, and complies with safety standards. It is integral to validating the effectiveness of new drugs and vaccines as well as evaluating the performance of skincare and disinfectant products. As such, efficacy testing is a fundamental aspect of product development, regulatory approval, and market entry.
