Located in Lyon's Gerland biodistrict, Episkin has been at the forefront of developing increasingly sophisticated reconstructed skin for over 30 years. This facility serves as a crucial site for L'Oréal, enabling them to conduct product testing and advance research in dermatological science. The laboratory's expertise lies in the creation of artificial skin, which is used to simulate human skin in various cosmetic tests.

The process of creating this lab-grown skin involves meticulously harvesting keratinocytes, the epidermis cells responsible for skin's protective qualities. After a month of incubation and careful manipulation in sterile environments, these cells develop into a fine, elastic membrane that replicates natural human skin in both texture and color. The end product plays a pivotal role in ensuring that L'Oréal's products are safe and effective prior to their market release.

This innovative approach not only supports the efficacy of cosmetic products but also represents a significant step in the cosmetics industry towards reducing the need for animal testing. By utilizing laboratory-created skin, L'Oréal and similar companies can address ethical concerns while still ensuring the quality and safety of their offerings, reflecting a growing trend towards ethical and sustainable practices in beauty and cosmetic research.
