To develop the safest and most effective products for your baby, our researchers need to know the specific characteristics and needs of your baby’s skin. By reconstituting the epidermis of a baby and young child in our laboratories, our teams gain an in-depth knowledge of the skin, its cells and genes, to better understand its physiology and development. This is the world’s first patented epidermis of its kind and only Laboratoires Expanscience’s Mustela researchers are able to perform these experiments. We also use reconstituted epidermises to test the effectiveness and tolerance factor of our products with a high level of precision and reliability.
