Effects of under-eye skin and crow's feet on perceived facial appearance in women of five ethnic groups.

Objective: Age-related skin changes in the periorbital region caused by intrinsic (e.g. atrophy of collagen and fat) and extrinsic (e.

A New Generation of Postbiotics for Skin and Scalp: In Situ Production of Lipid Metabolites by .

Effects of pre- and probiotics on intestinal health are well researched and microbiome-targeting solutions are commercially available. Even though a trend to appreciate the presence of certain microbes on the skin is seeing an increase in momentum, our understanding is limited as to whether the utilization of skin-resident microbes for beneficial effects holds the same potential as the targeted manipulation of the gut microflora. Here, we present a selection of molecular mechanisms of cross-communication between human skin and the skin microbial community and the impact of these interactions on the host's cutaneous health with implications for the development of skin cosmetic and therapeutic solutions.

Age-dependent changes in skin features and perceived facial appearance in women of five ethnic groups.

Objective: Research documents effects of skin features on assessments of age, health and attractiveness of female faces. Ethnic variation also has been reported for the impact of age-related changes in skin features on face assessments. Here, we investigate women's self-ratings across age cohorts and ethnic groups and discrepancies with (non-expert) assessor ratings of facial appearance together with age-dependent changes in skin features.

Menopause and facial skin microbiomes: a pilot study revealing novel insights into their relationship.

The human skin microbial composition is affected by age. Previous studies reported skin microbiome diversity shifts between elderly and significantly younger subjects. Some studies implied that menopausal status, which is inherently linked to age, could be associated with changes in skin microbial compositions.

Predictors of female age, health and attractiveness perception from skin feature analysis of digital portraits in five ethnic groups.

Objective: Research indicates the impact of skin colour, tone evenness and surface topography on ratings of age, health and attractiveness in women. In addition to subjective assessments, these effects have been quantified with objective measures derived from skin image analysis. Signs of skin ageing may manifest differently across ethnic groups.
