StatistiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Jaka Biotech reveals the findings of a study that indicates the topical use of a Lotus corniculatus seed extract yields clinical benefits in reducing sebum production and enhancing skin pore appearance for individuals with oily skin.
The increasing popularity of botanical ingredients in skincare and haircare is attributed to their efficacy and natural origins. However, limited research has focused on the synthesis and secretion of sebum. This study aims to explore the novel composition of Lotus corniculatus seed extract (Smopore LC) and its inhibitory effects on lipogenesis in SZ95 sebocytes. Topical application of Smopore LC resulted in an immediate and long-lasting reduction in sebum content and sebum area on Chinese oily skin, achieved by downregulating sebaceous lipogenesis through the LA and DHT pathway. Smopore LC shows promise as a new botanical ingredient for oily skin.Note de contenu : - MATERIALS AND METHODS : LC composition analysis - Cell culture - Cell staining

Tests de sécuritéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Electrical epilation of unwanted hair is a widely used hair removal method, but it is largely unknown how this affects the biology of human hair follicles (HF) and perifollicular skin. Here, we have begun to explore how mechanical epilation changes selected key biological read-out parameters ex vivo within and around the pilosebaceous unit.
- Methods : Human full-thickness scalp skin samples were epilated ex vivo using an electro-mechanical device, organ-cultured for up to 6 days in serum-free, supplemented medium, and assessed at different time points by quantitative (immuno-)histomorphometry for selected relevant read-out parameters in epilated and sham-epilated control samples.
- Results : Epilation removed most of the hair shafts, often together with fragments of the outer and inner root sheath and hair matrix. This was associated with persistent focal thinning of the HF basal membrane, decreased melanin content of the residual HF epithelium, and increased HF keratinocyte apoptosis, including in the bulge, yet without affecting the number of cytokeratin 15+ HF epithelial stem cells. Sebocyte apoptosis in the peripheral zone was increased, albeit without visibly altering sebum production. Epilation transiently perturbed HF immune privilege, and increased the expression of ICAM-1 in the bulge and bulb mesenchyme, and the number of perifollicular MHC class II+ cells as well as mast cells around the distal epithelium and promoted mast cell degranulation around the suprabulbar and bulbar area. Moreover, compared to controls, several key players of neurogenic skin inflammation, itch, and/or thermosensation (TRPV1, TRPA1, NGF, and NKR1) were differentially expressed in post-epilation skin.
- Conclusion : These data generated in denervated, organ-cultured human scalp skin demonstrate that epilation-induced mechanical HF trauma elicits surprisingly complex biological responses. These may contribute to the delayed re-growth of thinner and lighter hair shafts post-epilation and temporary post-epilation discomfort. Our findings also provide pointers regarding the development of topically applicable agents that minimize undesirable sequelae of epilation.Note de contenu : - MATERIALS AND METHODS : Human samples - Human skin organ culture and ex vivo epilation - Ex vivo assessment of epilation - Histochemistry - Immunohistochemistry and immunofluorescence microscopy - Microscopy and quantitative (immuno-)histomorphometry - Statistical analysis
- RESULTS : Epilation ex vivo removes almost the entire hair shaft and induces morphological changes in the HF epithelium - Epilation reduces follicular melanin content and melanogenesis ex vivo - Epilation selectively promotes apoptosis in hair matrix and bulge epithelium but does not compromise the epithelial stem cell pool ex vivo - Epilation induces sebocyte apoptosis but does not appear to alter sebum production - Epilation ex vivo transiently perturbs HF immune privilege - Epilation induces perifollicular inflammation ex vivo - Epilation causes transient changes in the expression of key components of neurogenic skin inflammation, thermoregulation, itch, and/or pain in HFs ex vivoDOI : https://doi.org/10.1111/ics.12923 En ligne : https://drive.google.com/file/d/1U7feLvo9Dv8VxiJ9cipcR_p0N6MbplFC/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=40906

Soins de beauté masculinsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Shaving means stress to the skin and a good aftershave will cairn and soothe the skin by reducing skin irritation and restoring moisture. Creating such a product that also responds to major trends in the personal care market such as being alcohol-free and composed of ingredients from natural origin is a real challenge. Here, we present an aftershave balsam with a natural formula containing potassium lactate and with proven anti-irritant and moisturising properties. Both chromameter and Corneometer® data from skin treated with the balsam showed significant improvements in skin redness and hydration level, but also the sensory perception of the product was convincing. Therefore, potassium lactate can be considered as a genuine natural alternative to conventional functional ingredients in aftershaves. Note de contenu : - Methods
