Dual asymmetric centrifugation to prepare cosmetic emulsions and creams: Physico‐chemical and energy considerations

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Dual asymmetric centrifugation (DAC) enables the preparation of stable cosmetic emulsions and structured creams with physicochemical, rheological and textural properties comparable to those of conventional processes. At larger scales, DAC also offers competitive energy efficiency by avoiding heating steps, supporting more sustainable cosmetic ...

Trans‐resveratrol alleviates inflammation and improves skin barrier function via aryl hydrocarbon receptor pathway in human reconstructed epidermis

open access: yesInternational Journal of Cosmetic Science, EarlyView.
In a cytokine‐challenged human epidermal model, trans‐resveratrol reduces inflammation (IL‐1α) and oxidative stress markers (CYP1A1, CYP1B1), while modulating the expression of barrier‐related genes (LOR, OCLN) and differentiation‐associated CASP14. This supports its role as a multifunctional active for sensitive and compromised skin.

Pretreatment of keratinocytes with Galactomyces ferment filtrate (GFF) promotes stress resiliency in an in vitro oxidative stress model

open access: yesInternational Journal of Cosmetic Science, EarlyView.
GFF pretreatment enhances keratinocyte protection against oxidative stress by mitigating stress‐induced biomolecular changes and gene expression dysregulation. GFF‐pretreated keratinocytes maintain healthy epidermal biology post‐stress, preserving mitochondrial function and proliferative capacity.

Directional analysis of upper eyelid wrinkles and a quantitative index for periorbital ageing

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Eyelid wrinkles not only increase in number and depth but also shift in orientation with ageing. After 40, the dominance of a particular orientation in the upper eyelid image is associated with broader periorbital wrinkle severity, providing a novel quantitative index for fine‐grained ageing assessment. Abstract Objective Periorbital ageing, manifested

Environmental and lifestyle determinants of skin ageing: Association between skin dryness and dyspigmentation in Chinese women

open access: yesInternational Journal of Cosmetic Science, EarlyView.
The study of photoageing visible features in an Asian female cohort from rural and urban locations and across seasons evidenced a consistent correlation between skin dyspigmentation and dryness, suggesting mechanistic interplay, and emphasizing that these key concerns of ageing skin could be addressed more efficiently taken together.
