First live-broadcasting training event by Shanghai EPISKIN


Despite the impact from COVID-19 outbreak and restrictions on travel and conference gathering, the 9th EPISKIN Academy Workshop has just been successfully carried out through the live-broadcasting platform on Apr. 17th at Shanghai EPISKIN’s head office in Zhangjiang Hi-Tech park. This is also our FIRST online live-streaming show of technical training and product support to meet in vitro alternative testing related needs.

In our initiative to quickly adapt to the current circumstance with the agility to timely respond to our clients’ requests on technical training and support, given the fact that working activities cross sectors are recovering in China but regular on-site training still cannot be organized for the moment, this online workshop highly demonstrated the efficiency and effectiveness of such a new format for technical training and support.

Content of this 9th EPISKIN Academy Online Workshop:

1) Opening and Introduction


2) Review of in vitro Skin Irritation EpiSkin testing method (OECE TG439)

3) Demonstration of key technical steps of Skin Irritation Test using EpiSkin model and data analysis



4) Introduction of 3D skin models commercialized in China

5) Discussion Q&A


During the very special period we are all going through around the world, EPISKIN and the EPISKIN Academy are experimenting new way of communication using more and more digital technologies. This totally new way of sharing skin irritation protocols by live-broadcasting is a great success and we will soon provide other live sessions all over the world.

EPISKIN ACADEMY poster reward at the 57th SOT



Brazil is the third country, after France and China, to produce locally an EPISKIN model. The SkinEthic RHETM model, used during the training, is produced through collaboration between L'Oréal and the Brazilian D'Or Institute for Research and Education (IDOR). EPISKIN, world leader of reconstructed human tissues for 25 years developed a wide range of expertise of applications of these models in different scientific, technological and regulatory contexts for both safety and efficacy purposes. In 2012, EPISKIN Academy have been created to share this knowledge and to prepare next generation of stakeholders to face the challenge of 21st century toxicology. EPISKIN Academy promotes and trains scientists all over the world to alternatives to animal testing in toxicology. To date more than 300 scientists have been trained in Europe, ASIA and America.

 Episkin Academy China


EPISKIN Academy created in China



L'Oreal China and Shanghai EPISKIN Biotechnology Ltd. announced the creation of the EPISKIN Academy in China.
Through training and technical collaborations, the Academy will work with Chinese scientists, key opinion leaders, students and future stakeholders in terms of scientific and regulatory issues for alternatives to animal testing in field of safety, toxicology and efficacy as well as in other relevant areas.

To further promote the reconstructed skin models through marketing, L'Oréal China and EPISKIN SA created Shanghai EPISKIN Biotechnology Ltd. in 2014 to produce reconstructed skin models according to high quality standards in the industry. The models will be used primarily for research on skin tissue engineering and testing. This time the creation of the EPISKIN Academy will certainly play an important role in promoting in vitro skin models in the industry.

"In China, the Academy will work closely with various parties to promote the reconstructed skin models and alternative methods in China, and will strive to become a key scientific resource to further stimulate innovation in the Chinese cosmetics industry" said Dr. Christian Pellevoisin, scientific Director of the EPISKIN Academy.

New Dedicated Training sessions are coming...

Episkin Academy training: ENMV Sidi Thabet- Tunisia, february 23-26, 2015

The National School of Veterinary Medicine Sidi Thabet organized a training in animal experiments which  theme was: "From in vivo models to cell models".

This training took place in ENMV of Sidi Thabet (University of Manouba) and lasted 4 days from 23 to 26 February 2015.

34 participants (biology doctoral students, teacher-researchers, veterinarians, industrial and control pharmacists) were informed of the new cell technologies and alternative methods which aim to replace animals in drug-Toxicological, chemical and cosmetics testing. Practical workshops and round table helped to promote exchanges and networking with European partners.

Main objectives:

  • Promote good practice and ethics in animal experimentation based on the principle of the 3Rs (Replacement, Reduction, Refinement).
  • Presentation and training on new cellular technologies (2D and 3D) on two organs: liver and skin (primary liver cells, liver microsome, skin cells ...) in the pharmaco-toxicological and pharmaceutical research.
  • Present the situation in Europe and internationally of the new technologies (in silico, in vitro, omics "adverse outcome pathways") in the academic and regulatory (REACH) context.

This training also offers an opportunity to discuss collaborative projects (medium and long term) with the scientific and medical community as well the pharmaceutical industry in the new research program called European "Horizon 2020" and beyond.

The Episkin Academy presented the Pharmacotoxicology applications of the 3D reconstructed human epidermis models during the round table. This presentation was followed by a training session on the use of our epidermal tissues.
