Natural clays can provide this need through their capacity to interact with the skin, while treat them in a positive way.
The physical-chemical properties and the mineral composition supplied by clays (specially to kaolinite type), bring beneficial properties for skin, such as source of essential minerals, strength to the barrier function, detox and matte effect, and improvement of rheological parameters of formulations.
Thanks to their versatility, clays can be use in formulations for skin, providing cleaning effect, action against pollution and toxins, and also new formulas for solid cosmetics, which increases stability of formulations.
Interestingly, Brazilian clays present additional benefits in a performance-based multifunctionality, improving skin conditions through maintenance of hydration, and decrease of TEWL evaluated in short-time and long-time proof-of-concept studies, after clays foundation type formulation application in healthy skin participants.
Results obtained from that provide information regarding effectiveness on skin hydration, and skin barrier function through the decrease of the trans epidermal water loss ensuring the promotion of skin healthiness.Note de contenu : - MATERIALS AND METHODS

RhamnoseLe Rhamnose est un désoxyose, précisément un désoxy-hexose du mannose.
Le rhamnose est un 6-désoxy-hexose du type aldose, il est constitué d’une chaîne de 5 éléments carbone ainsi que d’une fonction aldéhyde. Il peut être classifié soit comme un méthyl-pentose ou soit comme un 6-déoxy-hexose.Index. décimale : 668.5 Parfums et cosmétiques Résumé : The dermal epidermal junction (DEJ) is a complex structure (Fig. 1) primarily responsible for epidermis to dermis attachment. The DEJ thus warrants cohesion and mechanical resistance of the skin. It also behaves as a selective permeability barrier controlling cell migration (immune cells, for example), and molecular exchanges (growth factors and nutrients, stress signals). Epidermal cells'interaction with the DEJ regulates their proliferation, differentiation and migraton, which is critical for epiderma renewal, barrier function setup, and wound healing.
Intrinsic and extrinsic ageing are associated with important DEJ structural modifications including flattening (loss of rete ridges), duplication and thinning (Fig. 3b). At molecular level, there is a decreased expression of the main DEJ constituent-proteins : collagens type IV, VII and XVII, laminin 5 and integrin β4. All these changes likely participate in structural and functional changes associated with ageing skin (elasticity loss, higher fragility, decreased resilience to stress, impaired wound healing). In photo-aged skin, degradation of some specific DEJ constituents such as heparan sulfate causes permeability modifications that were reported to participate in age spots formation.
Therefore a large array of cosmetic benefits can be expecteed from DEJ protection and repair. Here we describe the properties of an original bioavailable rhamnose derivative, its mechanism of action, and clinical improvements obtained after four weeks of treatement.Note de contenu : - Design of a bioavailable rhamnose derivative

Photovieillissement (dermatologie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : In our hyper-connected world, we spend countless hours in front of digital screens emitting blue light (BL) with the general perception that this is safe for our skin, but the infiltration of electronic devices in our daily lives does not come without consequence. There is scarce data that touches on the effects of BL on human skin. Moreover, the data available so far has been performed on basic cellular models that are far from the complexity of human skin. This study focuses on the identification of the BL induced damage using 3D models. We found that direct BL exposure to the skin generates ROS leading to oxidative stress marker generation including protein carbonylation, nitrotyrosine, 4-hydroxynonenal. In addition, the expression of matrix metalloproteinase-1 which is responsible for extracellular matrix degradation during chronological aging and photoaging processes is increased. These data show that blue light emitted by electronic devices affect skin health and may be involved in premature aging.

Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : As we are living in a world full of uncertainties, where we are challenged by the coming together of environmental, health and employment crises, mental and physical stresses tend to overwhelm us. These stresses have deleterious effects on human body and especially on skin. They lead to the impairment of cell bioenergetic functions, thus contributing to premature skin aging. To recover serenity, being inspired by Japanese traditions and their Zen aesthetic principles can be a new way to address daily stresses. This paper presents the concept of Zen aesthetics that allowed us to develop several formulations under the beauty concept called “Zenspiration”. Among these formulations, the Energizing Water Cream is dedicated to re-energizing stressed cells. This paper also describes the skin biological benefits provided by an active ingredient called Rootness™ Energize, included in the Energizing Water Cream, and developed thanks to the plant milking technology. This extract from the roots of Luffa cylindrica demonstrated in vitro its ability to protect and stimulate cell bioenergetic functions while stimulating antioxidant defense systems and accelerating the renewal of key extracellular matrix components. A clinical study enrolling stressed women demonstrated that Rootness™ Energize improved skin elasticity and firmness in stressed women, leading to a reduction in wrinkles. Note de contenu : - RESULTS AND DISCUSSION : Rootness™ Energize has a unique composition enriched in bryonolic acid - Rootness™ Energize preserves and boosts stress impaired mitochondrial bioenergetic cellular functions - Rootness™ Energize stimulates intrinsic antioxidant defense cellular mechanism impaired by stress - Rootness™ Energize stimulates the renewal of key extracellular matrix components to support skin homeostasis - Conclusion
