Independent Testing: Ensuring Efficacy & Objectivity

Rigorous testing: clinical evaluation, consumer assessments, and cutting-edge instrumental evaluations. Every product benefit is independently tested and validated.
To guarantee objectivity in our clinical testing, we conduct "double-blind" studies. This means that both the independent test centers and the consumers evaluating our products are unaware of the product's identity and its intended purpose. By removing any biases, we can obtain an objective evaluation of the formula's performance.

DID YOU KNOW? Prior to reaching your skin, each product undergoes a minimum of 400 applications in controlled, independent research settings. This extensive testing process ensures that our products meet the highest standards of efficacy and safety.

At L'Oréal Paris, we are dedicated to provide you with skincare products that have been thoroughly tested and proven effective. You can trust that our commitment to independent testing guarantees the quality and performance of our products.
