Tolerance and safety
Before they are marketed, each ingredient and each formula are tested to ensure that the use of the cosmetic product will be well tolerated by the skin.
Each cosmetic ingredient is evaluated before registration and use to ensure that it does not present a risk of genetic or general toxicity to humans. This assessment can be carried out by analyzing the safety data available in the scientific literature, by characterizing the active molecules in the case of plant extracts, or by carrying out in vitro tests for irritation or skin sensitization, for example. All animal tests are prohibited by the European cosmetics regulation since 2013.
Toxicity of formulas: skin and eye tolerance
The formulas developed are tested before being placed on the market to ensure that they are perfectly safe for the skin, eyes or mucous membranes, depending on their use. These tests can be performed in vitro on specifically developed cellular models or on voluntary panelists according to a clinical study protocol. The panels used may be representative of a particular category (e.g., sensitive skin), and the tests carried out under medical supervision as required.
In order to ensure optimal consumer safety when using sunscreen products, various tests are carried out by independent laboratories. Thus, the sun protection factor (SPF, UVB protection), or the UVA protection factor are determined in vitro or on panelists in the laboratory using specific solar lamps.
Other claims can also be verified such as resistance to water, sand, or perspiration.
Cosmetic product safety report
Once these tests have been carried out, and before any commercialization, an independent toxicologist evaluates the safety for human health of the use of each new cosmetic product. This expertise ensures consumer safety.
