3D printing continues to develop and concerns more and more sectors, and it is now that of cosmetics which is concerned through a partnership signed between L'Oréal and Organovo.
L'Oréal has committed since 2013 to no longer carry out animal tests for all of its cosmetic products. But to be able to certify most of its products, the group must still conduct clinical tests.
To do this, the firm turned to human skin samples made in the laboratory on the principle of cultivation. Unfortunately, this production method is intended to be slow and no longer meets the growing needs of L'Oréal (which thus requires more than 130,000 samples per year).
The solution to which the group turns comes in the form of Oganovo, a company that specializes in printing human skin in 3D. The technique used already makes it possible to recreate living tissues such as the liver or the kidneys, but the technique of manufacturing human skin is intended to be sufficiently advanced to correspond to the needs of cosmetic laboratories.
Thanks to these skin samples, L'Oréal should be able to accelerate the development of its products, without going against animal protection associations and while taking advantage of tests closer to reality.
