In-line links or any other process aimed at integrating parts of this site on third-party sites are prohibited. This prohibition does not apply to situations in which the User relays information on the Site within social networks such as Facebook, Instagram, LinkedIn or Twitter.

These Terms apply only to this Site, and not to websites owned by third parties. We sometimes provide links to other websites that we believe may be of interest to the User. In such cases, we ensure that these first degree links meet the highest standards of computer security. However, due to the nature of the Internet, we cannot be held responsible for the content of sites other than this one, the present Conditions not being applicable to non-Cristalens sites.


In application of the transparency regulation of the law of December 29, 2011 relating to the reinforcement of the sanitary safety of medicines and health products, Cristalens is required to make public the existence of agreements and benefits of at least €10 including tax (including amounts which, rounded to the nearest euro, are equivalent to €10 including tax) benefiting the categories concerned by the said law.

This law guarantees the independence and impartiality of decisions taken in the field of health. It imposes transparency of the links between the health industries and other actors in the health field, health professionals, students, learned societies, associations, media, etc.

Links of interest do not mean conflicts of interest. In order to develop their products, companies have to establish relationships with experts, journalists and public actors. Of course, this complementarity must be preserved and developed, as it advances science and allows therapeutic progress. But these links must be known to all and easily accessible.

Since April 1, 2014, the information has been published on the single public site set up by the government in accordance with the implementing decree of May 21, 2013 on the transparency of links of interest and the order on the installation of the single public site for the publication of links of interest published on December 19, 2013 in the Official Journal at the following address: https://www.transparence.sante.gouv.fr/flow/main?execution=e3s1
