For every product, we evaluate the safety of the raw ingredients and also
of the finished product.
Firstly, we analyse the composition of the formula and calculate the margins of
safety for the concentration of each ingredient. Then, we set up preclinical
tests (in vitro), clinical tolerance tests (in vivo on healthy skin and then the target),
sensitisation tests and finally skin and/or ocular tolerance tests.
When developing our formulas, if we encounter any problem during
these tests then, without question, the product is not marketed and is started again from square one. At
Eau Thermale Avène, safety comes first and foremost. Every product is therefore placed on the
market with the absolute guarantee that it is safe under normal conditions of use.
