Régénération (biologie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : Ashland has unlocked the secret of our skin at night so you can awaken like Sleeping Beauty from your slumber, with skin re-set for the day ahead. Ashland Nightessenceâ„¢ biofunctional was developed to enhance the naturally occurring nocturnal process that helps skin boost molecules such as timezyme and melatonin.
Leveraging off the current beauty sleep trend, this is the first biofunctional of its kind tailored to understand and optimise skin’s nighttime needs. It helps restore it overnight, so skin looks rested, renewed and illuminated by morning.
Nightessence was eco-consciously designed from field-to-skin. Our premium lavender is grown sustainably on the mountain slopes in Provence, France, and the flowers are extracted using Ashland’s proprietary Plant Small RNA technology to offer a novel type of lavender essence to the cosmetic market.Note de contenu : - The 'blue gold' of Provence Alps, on the road of summer

KératinocytesLes kératinocytes sont des cellules constituant 90 % de la couche superficielle de la peau (épiderme) et des phanères (ongles, cheveux, poils, plumes, écailles). Ils synthétisent la kératine (kératinisation), une protéine fibreuse et insoluble dans l'eau, qui assure à la peau sa propriété d'imperméabilité et de protection extérieure.
L'épiderme est divisé en 4 couches basées sur la morphologie des kératinocytes (de l'intérieur vers l'extérieur) :
1. stratum germinativum (couche basale à la jonction avec le derme)
2. stratum spinosum
3. stratum granulosum
4. stratum lucidum
5. stratum corneum
Les kératinocytes passent progressivement de la couche basale vers les couches supérieures par différenciation cellulaire jusqu'au stratum corneum ou ils forment une couche de cellules mortes nommées squames, par apoptose. Cette couche constitue une barrière de protection et réduit la perte d'eau de l'organisme.
Les kératinocytes sont en perpétuel renouvellement. Ils mettent environ 1 mois pour aller de la couche basale au stratum corneum mais ce processus peut être accéléré en cas d'hyperprolifération de kératinocyte (psoriasis).

Stress oxydatifIndex. décimale : 668.5 Parfums et cosmétiques Résumé : As a complex sensory organ in the first line to sense external signals, our skin contains multiple receptors intended to response to touch perception, as well as thermal variation and pain. Moreover, recent studies highlighted the presence of photoreceptors and tasting receptors in human skin, whose function is still poorly described. The fact that these receptors can functionally respond to external stimuli, in particular to blue light and bitter compounds, allows us to consider a role in skin alert under environmental stresses. The present study aims at investigating the presence of opsin photoreceptors and bitter taste receptors in human skin, and to evaluate their response to stress induced either by exposure to blue light or smoke pollution. Blue light representing High Energy Visible (HEV) light was shown to be associated with the generation of oxidative stress, which is associated with skin photo-damage. Blue light pollution refers to artificial blue light exposure associated with 4 hyper-connected lifestyle. For the purpose of overall protection of the skin, protection from blue light pollution may help minimize its detrimental effects, which are associated with digital aging. In a second approach, receptors for bitter tasting were studied aiming at improving skin response to pollution stress.

EpigénétiqueL'épigénétique (mot-valise de "épigenèse" et "génétique") est la discipline de la biologie qui étudie la nature des mécanismes modifiant de manière réversible, transmissible (lors des divisions cellulaires) et adaptative l'expression des gènes sans en changer la séquence nucléotidique (ADN)
"Alors que la génétique correspond à l'étude des gènes, l'épigénétique s’intéresse à une "couche" d’informations complémentaires qui définit comment ces gènes vont être utilisés par une cellule ou… ne pas l'être".
"C'est un concept qui dément en partie la "fatalité" des gènes".

Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Over the past several years, a number of scientific papers have been published that suggest the skin pigmentation process can be fully mapped by following the cellular pathways and the molecules involved in melanogenesis. Indeed, it has been know for years that epidermal units within the skin generally serve to produce and distribute melanin; however,the regulatory process that controls pigmentation is now only coming into view; Understanding the regulatory pathways to melanogenesis will help the cosmetics industry in their effort to develop safe and effective strategies to temporarily brighten skin tone for cosmetic effects.
Epigenetics is a process that leads to stable and heritable changes in gene expression without changes in the underlying DNA sequences. A new area of study, epigenetics science opens the door to discovery of melanin regulation. The research effort finds its roots in the medical community, where it is postulated that new approaches to treating cancer other than fixing or replacing damaged genes may also help to improve patient outcomes.
The opening for epigenetic science began about 25 years ago after scientists discovered a distinct class of biologic regulators called miRNA. These small non-coding ribonucleic acids serve to fine tune the expresson of approximately 30% of all protein-encoding genes. The miRNA usually induces gene silencing by binding to messager RNA (mRNA). The interaction of a miRNA and its mRNA targets tends to prevent protein production by suppressing mRNA translation and/or by prompting mRNA degradation.
The following research describes pathways to modulate miRNA epigeetic regullators in skin cells for cosmetic effects. Research outlining the down-regulation of miRNA-29a and the resulting effects in collagen synthesis and in prolidase activity is introduced as an example of the potential to utilise miRNA pathways to improve the appearance of skin. Moreover, miRNA-218 is considered for its role in regulating melanogenesis. A clinical study with 35 volunteers is also described, wherein hexapeptide-2(Trade Name : Dermostatyl IS biofunctional) is examined for its ability to brighten skin tone.En ligne : https://drive.google.com/file/d/18Q4_iCLlQpR2htJRg1sqJqMjs1ykvGQy/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=24964
