Sun simulator: sunlight reproduced in the laboratory

The sun simulator is laboratory-induced sunshine that reproduces all the conditions such as the midday sun, the summer sun, the winter sun or the Miami sun. This provides realistic conditions of sunlight and hence ultraviolet radiation. Françoise Bernerd, Head of L'Oréal’s Light and Pigmentation Laboratory, explains how reconstructed skins placed in this solar simulator enable the biological effects of this radiation on our skin cells to be studied.
