The BIO-EC laboratory always looking for innovation to bring you the best solutions is invested in many collaborative research projects.


  • 2016-2019

The project S’KIN is a FUI project certified by cosmetic valley and Lyon Biopôle which is conducted by BIO-EC laboratory, Chimex, Dermadis, Labo-BF and SATIE laboratory from Cergy-Pontoise University.

This three years- project which has started in 2017, aims to develop et commercialise new anti-protease cosmetic ingredients to treat the cutaneous disorders of sensitive skin, atopic-like or with acne or rosacea. The characterization of these products will be performed using new cutaneous biological models mimicking the sensitive skin disorders, as well as using innovative measurement systems.

BIO-EC laboratory was financed by La région Ile de France.


  • 2016-2018

The physiology of human body is highly affected by abiotic stresses from the external environment including UVs, extreme temperatures and atmospheric pollutants.

Atmospheric pollutants include polycyclic aromatic hydrocarbons (PAHs) volatile organic compounds (VOCs) and fine particle pollution (PM10 and PM2.5).

The main goal of the UrbaSkin project, a project labeled by the competitive pole of Cosmetic Valley, is to analyze and characterize the impact of atmospheric pollution on human skin biology and physiology in order to develop new cosmetic products with anti-pollution activity.

BIO-EC laboratory is the leader of this multi-disciplinary research project.

Other partners are two research units from the academic area: the Glyco-Mev laboratory of Rouen University and URCOM laboratory from Le-Havre University and three private companies working in the dermo-cosmetic field: BIO-EUROPE (Solabia Group) laboratory, GENEX laboratory and the Uriage Dermatological Laboratories.


  • 2014-2017

Glycoskin I is a research project about the identification of new active substances (phosphosaccharides) and formulae acting on a non-exploited modulation pathway of the cutaneous pigmentation with simultaneously the development of tests and the realization of measures.

The project is run by Libragen Company, which is specialized in the development via biocatalysis (green chemistry) of glycoconjugate molecules which will find an application in dermocosmetics.

Partners are « Glycobiology and Cell recognition » team from Molecular and Biophysics center, UPR4301, CNRS, Orléans, Tebu-bio Company specialized in safety test and in vitro substantiation, BIO-EC Laboratory whose expertise is the substantiation on human living skin explants, GlycoDiag Company specialized in the identification of cellular glycanes and finally, the Ales group for his know-how in active galenic formulation with a strong penetrating power and devoid of surfactants.

The originality of this collaborative project lives in the fact that it addresses a subject of research completely in adequacy with the demands of a world market always more applicant, and it joins almost all the jobs by the value chain of the cosmetic sector for the elaboration of innovative cosmetics and by using it the green chemistry.


  • 2012-2017

The Blue Hyal project objective is to structure know-how on the modulation of polysaccharides from micro seaweeds with the aim of the realization, customized, of “greens” polysaccharides with high application specificity such as stabilizers of emulsion, anti UV or hydrating activity support which will be the first products developed during the program.

Based on exclusive exopolysaccharides of micro seaweeds and stemming from the R&D of our partners, those products will position as “green” substitute of the hyaluronique acid and analogues from not renewable GMO resources.

Products development will involve a pushed study of the biotechnological ways of modification of polysaccharides as well as their functionalization and reticulation by soft chemistry more particularly bu the ground-frost process (SG).

Products will be characterized by a physico-chemical point of view and a biological activity, by using and by optimizing new non-destructive systems of on-line measure and new tests of cosmetics substantiation on human living skin explants. A study of the modalities of industrializations according to the sustainable development will be realized, with the design and pilots’ realization of production and their optimization. Cosmetic qualification (activity on finished product, safety study) will be conduce on the resultant products as well as an environmental impact study and a cost estimate of industrial production.


  • 2011-2015

The project ALOCA 2 is a FUI project certified by Cosmetic Valley which was conducted by BIO-EC laboratory, the “institut européen de Biologie” of the group UNIPEX/ Lucas Meyer Cosmetics, Alès groupe, and the institutions of INSERM (with Sabouraud center) and of ICSN/ CNRS.

During these four years-project (2011-2015), transcriptomics and protein analyses, performed in vivo, in vitro and ex vivo, allowed us to figure out the biological mechanisms involved in hair loss (alopecia) and hair graying. The results were described in scientific publications and communications.

This project resulted also in new tests applied for the characterization of alopecia and hair graying, as well as the development of new cosmetic active ingredients efficient against these hair disorders; commercially available and/or patented.

BIO-EC laboratory was financed by BPI France.


  • 2009-2012

The Skin-O-Flor project, a project labeled by the competitive pole of Cosmetic Valley, has been realized in collaboration between 5 different laboratories including two research units of Rouen University: the Glyco-Mev laboratory and LSMS laboratory.

Three additional laboratories, including BIO-EC laboratory, BIOEUROPE laboratory (Solabia Group) and the Uriage Dermatological Laboratories have participated at this project.

The project allowed developing new cosmetics for healthy sensitive skins to maintain and improve the organic-physic-chemical barriers properties of the healthy sensitive skin in front of its microbial environment.

BIO-EC Laboratory thanks to its dermocosmetic expertise, participated actively in the various stages of the SKIN O Flor project, and more particularly it contributed to develop the following stages:

  • Study of the skin flora, thanks to surface stripping realized on volunteers recruited by BIO-EC.

  • Molecular response analyze, from cutaneous cell after human living skin explants treatment with 3 different germs: epidermidis, S .aureus and P. fluorescens.

  • Analyze of different glycomelcules effects on the cutaneous defense link with the microbiota.

  • Raman spectroscopy analyze of normal skin and sensitive skin treated or not with corporal milk and cleaning oil “Xemose” conditioned by LDU.
