L’Oreal Paris uses a combination of clinical evaluation by experts and dermatologists, self-assessments by real consumers, and state-of-the-art instrumental evaluations to measure our products efficacy. Every product benefit you read on our L’Oreal Paris Skincare products has been tested by unbiased independent research organizations.

To ensure objectivity in clinical testing, our products are tested “double blind.” This means that neither the independent test centers nor the consumers evaluating our products have knowledge of what the product is or what it is intended to do, allowing for an objective evaluation of formula performance.
