Abstract: The skin is a complex ecosystem colonized by millions of microorganisms, the skin microbiota, which are crucial in regulating not only the physiological functions of the skin but also the metabolic changes underlying the onset of skin diseases. The high microbial colonization together with a low diversity at the phylum level and a high diversity at the species level of the skin is very similar to that of the gastrointestinal tract. Moreover, there is an important communication pathway along the gut–brain–skin axis, especially associated with the modulation of neurotransmitters by the microbiota. Therefore, it is evident that the high complexity of the skin system, due not only to the genetics of the host but also to the interaction of the host with resident microbes and between microbe and microbe, requires a multi-omics approach to be deeply understood. Therefore, an integrated analysis, with high-throughput technologies, of the consequences of microbial interaction with the host through the study of gene expression (genomics and metagenomics), transcription (transcriptomics and meta-transcriptomics), and protein production (proteomics and meta-proteomics) and metabolite formation (metabolomics and lipidomics) would be useful. Although to date very few studies have integrated skin metabolomics data with at least one other ‘omics’ technology, in the future, this approach will be able to provide simple and fast tests that can be routinely applied in both clinical and cosmetic settings for the identification of numerous skin diseases and conditions. It will also be possible to create large archives of multi-omics data that can predict individual responses to pharmacological treatments and the efficacy of different cosmetic products on individual subjects by means of specific allotypes, with a view to increasingly tailor-made medicine. In this review, after analyzing the complexity of the skin ecosystem, we have highlighted the usefulness of this emerging integrated omics approach for the analysis of skin problems, starting with one of the latest ‘omics’ sciences, metabolomics, which can photograph the expression of the genome during its interaction with the environment.

Abstract

Objective: Periorbital skin ageing signs are multidimensional, highly visible and a concern for many. We evaluated the potential efficacy of an eye cream to diminish these signs.

Methods: Biological markers associated with ageing, barrier function and homeostasis were analysed in vitro to determine the effects of topically applied eye cream, compared to those of a placebo using human skin tissue models and/or explants. Collagen IV, elastin and bone morphogenic protein 4 (BMP4) expression was investigated by immunohistochemical labelling, while filaggrin, kallikrein 7 (KLK7) and HB-EGF were evaluated by RT-qPCR. IL-1α and melanin levels in darkly pigmented skin models were also quantified. The protective effect of the cream on glycation was assessed by a non-enzymatic assay. Finally, the benefits of twice-daily applications of the eye cream for 56days were instrumentally and clinically evaluated on 33 women.

Results: Only the eye cream, not the placebo, stimulated collagen IV and BMP4 protein expression, as well as increased elastin fibre length. It also led to higher HB-EGF, filaggrin and KLK7 mRNA levels. The placebo and the eye cream did not induce changes in IL-1α and melanin levels, but both reduced non-enzymatic glycation. When assessing the in  vivo effects of the cream, short-term results indicated skin hydration, transepidermal water loss (TEWL) and skin profilometry improvement within 15min. Instrumental evaluations of wrinkles showed a reduction after 7days, which was clinically perceivable after 28 or 56days. The eye-opening angle and eyelid sagging also improved after seven and 28days, respectively. Finally, dark circles became lighter within 7days (instrumental measurement) or 28days (clinical assessment).

Conclusion: The instrumental and clinical evaluations revealed that the eye cream reduced all periorbital ageing signs evaluated. Its effects are supported by the in vitro and ex vivo analyses of molecular markers.
