An international research team has discovered a positive association between microbes present on the skin and the infamous crow’s feet wrinkles. It is possible to develop revolutionary creams and treatments capable of preventing and attenuating the signs of aging on the face.

I researchers they found that some microorganisms who live on ours skin are associated with signs of aginglike the infamous (and hated) wrinkles around the eyesmore commonly known as “crow’s feet wrinkles”. In other words, these microbe they could be responsible for at least part of the wrinkles. This would explain the reason why people of the same age can have a more or less “marked” face, excluding other triggering factors – such asexposure to ultraviolet rays – which are widely recognized in making more dry e rough Skin. The discovery could result in innovative treatments e creme potentially revolutionary capable of to prevent o tone down the appearance of wrinkles.
To determine that the microbiome present on the skin could influence the appearance of wrinkles on the face was an international research team led by US scientists from the Jacobs School of Engineering at the University of California San Diego, who collaborated closely with colleagues at L’Oréal Research and Innovation of the famous French company producing cosmetics and other beauty products. The researchers, coordinated by Professor Se Jin Song, professor at the Center for Microbiome Innovation (CMI) of the Californian university, reached their conclusions after statistically analyzing the results of thirteen previous studies conducted by L’Oréal scientists.
More specifically, an in-depth analysis of the microbiota was carried out through the comparison of sequence data 16S rRNA amplicons (to bring out the taxa of microorganisms involved) ei clinical data linked to the participants’ facial skin. In all they were involved in the study further 650 donne with an age between 18 and 70 years. As highlighted by the researchers in the study abstract, in adulthood the skin microbiome “can be relatively stable if environmental conditions are also stable”, however skin aging and the resulting physiological changes can also influence the microbiome. Professor Jin Song and colleagues highlight that the skin signs typical of aging – such as wrinkles – and the parameters that indicate the quality of its surface (such as sebumpH, hydration, structure and others), “may not be indicative of chronological age”. This explains why there are young people with “elderly” skin and elderly people with “apparently young” skin.

By statistically analyzing genetic data from the microbiome and clinical data from the participants’ facial skin, the researchers determined that there is a positive association between diversity of the microbiome on the skin and crow’s feet wrinkles (but not between the diversity of the microbiome and the loss of transepidermal water, in practice the dryness of the same). In simple words, the microbes present on the skin could influence the chances of developing or not (or more or less intensely) this hated mark on the face. “Previous studies have shown that the types of microbes on our skin change quite predictably with age,” Professor Jin Song said in a press release. “Our skin also changes physiologically with age; for example, wrinkles form and the skin becomes drier. But there is variation in how it manifests itself in people: You’ve probably noticed that there are some people who have younger or older skin than many others their age. Using advanced statistical methods, we were able to distinguish microbes associated with these types of signs of skin aging, such as crow’s feet wrinkles, from those simply associated with age as a chronological number,” she said.
Thanks to these data and those that will be collected with future investigations, which will focus on the identification of chemical biomarkers and possible targets for genetic engineering, scientists aim to develop new products/treatments that can keep the signs of aging at bay and keep our skin healthier, beautiful and youthful even in old age. The details of the research “A multi-study analysis enables identification of potential microbial characteristics associated with skin aging signs” were published in the specialized scientific journal Frontiers in Aging.
