In order to preserve the health of babies' sensitive skin, CASTERA respects fundamental principles :

- CASTERA products requiring the presence of water are always formulated with Castéra-Verduzan Thermal Spring Water, the soothing, anti-oxidant and anti-irritant benefits of which are scientifically recognized. Numerous samples are taken throughout the year to ensure the composition of the thermal water.

- CASTERA products are all tested under dermatological control to be used safely on sensitive skin. To prove the harmlessness and effectiveness of CASTERA products, scientific tests are carried out by external companies approved by the Ministry of Research.

- Research and development teams are developing formulas by limiting the number of ingredients, so that they are simple but effective. The active ingredients are selected for their naturalness and purity. Our products are therefore natural or certified organic by Ecocert.

- All CASTERA products are produced without PEG (Polyethylene glycol), without silicone, without phenoxyethanol, without synthetic perfume, without GMOs, without animal or petrochemical raw materials, and of course not tested on animals.
