In the cosmetic field, claim substantiations face several challenges.One that could seem trivial is illustrating the performance of a product. With the growing awareness of subjects’ image rights and the implementation of more regulations to protect personal data, presenting the effects of a product using the very image of a subject becomes increasingly complicated.

The skin surface roughness is an indicator of interest for dermatology and cosmetology. Increased in xerotic skin or irritation, it is one of the most common frequent dermatological disorders.

In this study, our goal was first to functionally profile and characterize the response of normal human keratinocytes (NHEK) to microbial patterns (TLR agonists) and IL-1α in parallel. To do so, the effects of multiple TLR agonists and IL-1α were evaluated on the gene expression profile, on signal transduction (NF-ƘB translocation) and also on IL-8 and IL-6 release. Secondly, we also tried to link these responses to those of pathogens of interest in skin microbiota (namely, C. acnes, S. aureus and P. aeruginosa), by evaluating the effect on IL-8 release by NHEK infected with living bacteria from these 3 strains...

Dry skin is one of the most important concerns of consumers worldwide. Despite huge efforts over several decades, the personal care industry still does not offer a perfect solution to satisfy the unmet needs of consumers for moisturising treatments in different ethnic groups.

Evidence of a potential immunosuppressive effect of DHT.
Acne is a skin pathology targeting the pilosebaceous unit…sebum hypersecretion and bacterial infection. We studied the effects of living bacteria on the induction of an innate immune response in a sebocyte cell line.

Androgens are key regulators of sebaceous function... A link between mTOR and androgen signaling has previously been reported...as well as a link between these processes and lipid synthesis...Here we aimed at confirming that DHT-induced lipid synthesis/accumulation is at least in part dependent on mTOR activation in the SEBO662AR cell line and that the autophagic process is consequently modified by the androgenic treatment.

In this work, human epidermal keratinocytes were used to study the effects of urban dust and benzo(a)pyrene on the epigenetic pattern of the histone H3 protein. The assay was then used to screen a series of plant extracts in order to find cosmetic actives to protect the skin against air pollution.

L’acné vulgaris est une pathologie inflammatoire chronique cutanée localisée au niveau du follicule pilo-sébacé. Elle apparaît suite à une surproduction de sébum liée à des dysfonctionnements d’origine hormonale (androgène), environnementale (pollution…) et à la colonisation du follicule pilo-sébacé par certaines bactéries (P. acnes). (Dans ce contexte), QIMA Life Sciences a développé un panel de tests originaux destinés à la découverte et l’évaluation de composés pour le traitement de l’acné.

La glande sébacée est un organe localisé au niveau du derme. Elle est responsable de la synthèse et de la sécrétion du sébum qui entre dans la composition du film hydrolipidique. Le rôle du sébum est de protéger la peau des agressions extérieures et de la déshydratation. Le sébum permet également d’entretenir la souplesse de la peau et des cheveux.
