    Frequently asked questions about clinical trials?

    A clinical evaluation involves verifying, in humans, that our products are well tolerated under medical supervision, either under conditions designed to maximise their effects or under normal conditions of use, as well as assessing their efficacy.
    It is carried out in several stages. Following validation of the skin and eye compatibility of our formulations using in vitro (cell-based) models, our products are then applied to women and men in accordance with clearly defined and standardised protocols.

    The effectiveness of our treatments is measured using rating scales and quality-of-life questionnaires recognised within the dermatological community, as well as through instrumental measurements and image analysis, which enable us to assess, with a high degree of precision, changes in skin condition in terms of blemishes, sebum, hydration, etc.

    Clinical trials contribute to product innovation at DUCRAY by introducing new approaches to the assessment of the clinical signs of the skin conditions under investigation, in collaboration with our Medical and Research departments, and by utilising our trial results in different ways to develop innovative, unique products that meet the needs of our patients and healthcare professionals.
