Bio‐active designed peptide for hair keratin strengthening

International Journal of Cosmetic Science, EarlyView.
Bioactive tripeptides through in silico screening revealed KCV (Tripeptide‐132) as the most promising keratin‐targeting candidate. Experimental studies confirmed its superior hair‐strengthening performance with 44% tensile strength enhancement, 50% breakage reduction, improved surface integrity and fibre penetration.

Impact of ultraviolet radiation‐induced damage to hair fiber integrity: A multi‐technique physicochemical characterization of surface and cortex properties

International Journal of Cosmetic Science, EarlyView.
UV exposure induces cuticular and cortical damage in natural hair, with oxidative effects and protein degradation comparable to bleaching. However, double bleaching leads to significantly greater structural degradation, emphasizing distinct mechanisms and severity of chemical versus UV‐induced damage. Abstract The combination of chemist techniques is a

Protective effects of extracellular vesicle‐like nanoparticles derived from Cannabis sativa adventitious roots against UVB‐induced damage in human keratinocytes

International Journal of Cosmetic Science, EarlyView.
Cannabis sativa root‐derived extracellular vesicle‐like nanoparticles (CA‐NPs) were isolated from adventitious root cultures and subjected to physicochemical characterization. Upon UVB exposure, keratinocytes exhibited increased ROS generation, apoptosis and MAPK activation, leading to oxidative stress and skin damage.

A film of tuberose polysaccharide supports normal epidermal keratinization by suppressing cytokine release induced by external stimuli

International Journal of Cosmetic Science, EarlyView.
(a) Dry, rough skin has an immature stratum corneum prone to stimuli, triggering IL‐1α/IL‐1ra/IL‐8 release, keratinization defects, reduced ceramide NP/NS and lipids, scaling and poor hydration. (b) TPS forms a flexible reticular film, shielding the SC, lowering cytokines, normalizing differentiation, restoring lipids and improving texture and water ...

Less Happy, Though More Educated: What Explains Lower Life Satisfaction Among Highly Educated First‐Generation Immigrants in Highly Prosperous Countries?

International Social Science Journal, EarlyView.
ABSTRACT Conventional wisdom suggests that higher education (HE) and national prosperity (or wealth) contribute to improved life satisfaction. Is this also true for first‐generation immigrants? Using multilevel models on 16,368 individuals across 35 European countries from the European Social Survey, the results demonstrate that, although immigrants ...
