Garnier's Bioscreening Process


Everyday, we discover more and more ingredients from natural origin.
To select the best from nature and identify its activity on the skin, Garnier has adopted Bioscreening, a molecule screening method used in the pharmaceutical industry.


The Bioscreening used by Garnier comprises cell-culture facilities that operate a highly cutting-edge robot. The cell cultures placed in micro-well plates are inserted in a fully automatic incubator, and then retrieved by the robotic arm.

The robot allocates the products to be tested, moves the plates, dilutes the tested actives ingredients, freezes the solutions in order to remove dissolved gases, adds actives to cell cultures and manages the different protocol procedures before performing measurements.

In a single test process, 384 active ingredients can be tested. Data is then sent to molecular-modeling laboratories to obtain the ingredients properties and chemical characteristics. The Bioscreening tests have considerably increased Garnier's nature exploration capacities in skin care.

Each selected natural ingredient included in Garnier skin care products has also proven its activity through in vitro tests.
Each natural ingredient selected by Bioscreening is tested once again in vitro and its effects on skin-models are checked before being used in a Garnier skincare product.
