Sometimes he cellular aging it goes inside. It affects our well-being, but it cannot be seen with the naked eye. However, in the case of the skin, the famous wrinkles are the main sign indicating the passage of time. Obviously they are inevitable. We discovered long ago that there is no elixir of eternal youth and that no matter how much we age healthier, the years pass for everyone. Now, not everyone develops the same wrinkles at the same age, and it depends on many factors. Some like exposure to sunlight or smokingare well known. Now, however, it is believed that there may be others as curious as population changes. microbes living on our skin.
This is the conclusion of a recently published study by Scientists at the Jackson Lab in Connecticut. It should be noted that the study under review has not yet been peer-reviewed. Therefore, you should take their results with a grain of salt. However, it is interesting to know what other factors may influence appearance of wrinkles. Thus, even more measures than those already in place could be taken to delay its appearance.
This should be explored more, especially to find out how these skin bacteria contribute appearance of wrinkles. Meanwhile, it is worth remembering what we already know about them.
Why do wrinkles appear with age?
As skin cells age, there are several factors that affect appearance of wrinkles. In addition, they are associated with three layers of the skin: subcutaneous tissue, dermis and epidermis. The first thing that happens is that adipose tissueformed by fat decreases. At the same time, the thickness of the dermis decreases due to the loss of the fibrillar structure of the connective tissue and its ability to hold water. Finally, the consistency of the junction between the dermis and the epidermis is reduced.
Therefore, all this can be summed up by the fact that the skin becomes thinner, drier and sluggish. This leads to the appearance of the first wrinkles. expressions. A smile or a frown can make skin less elastic with age. loss of collagenit stays marked, like when we fold paper.
Influencing factors: from the sun to tobacco
Skin cell aging occurs throughout life. However, it becomes more noticeable from 25-30 years oldHence, this is the moment when so many people join the habit of using cosmetics on their skin.
Genetics is an important factor in the appearance of wrinkles. There are people who are more or less inclined to this. folds drawn on your skin. This, of course, is something that cannot be controlled. But there are other much more controllable factors that also influence their occurrence. more or less early.
The first of these is exposure to ultraviolet radiation from the sun. As we already know, they contribute oxidative processes in skin cells along with aging. A few months ago, an image from a study of a woman who has used facial sunscreen throughout her life went viral. But he forgot about the neck. The result was impressive, because it was clearly visible how that area was much more wrinkled and colored than the rest of the face.
On the other hand, it is impossible to talk about oxidation and cellular aging without referring to smoking. That is why numerous studies have been conducted, which show that indeed smokers tend to have much more wrinkles and also develop them earlier. Amazing cases have been seen even with twin brothers. Moreover, this is an effect that can also be seen with frequent alcohol use.
A case of wrinkles associated with skin microbiota
The skin microbiota is the collection of microorganisms that live in it. It has several functions, from direct defense against attack by pathogens for direct stimulation the immune system. However, there are three more, perhaps lesser-known features. One is the production of the characteristic smell of each person, the other is protection from ultraviolet radiation and finally, keeping the skin hydrated. The last two are directly related to wrinkles. We have already seen that the skin dehydrates over the years, and also that solar radiation accelerates the appearance of skin folds.
For this reason, these scientists wanted to see how the composition of the microbiota of a group of people of different ages affects the appearance of wrinkles. They could analyze wrinkles subjectively, simply by direct observation. However, they also studied collagen levelswhich is responsible for maintaining the elasticity and hydration of the skin.
In particular, cases 51 women living in Paris. About half of them were between the ages of 20 and 26, while the rest were between the ages of 54 and 60. They took cheek swabs from everyone, and then analyzed their microbial composition and came up with several interesting conclusions.
bacteria on the skin
The first conclusion was that there were three main types of bacteria: Cutibacterium acne, Epidermal staphylococcus aureus And Corynebacterium kroppenstedtii. However, the proportions of each varied with age and collagen levels in the skin. For example, c acne predominate in young women, while C. epidermal And C. kroppenstedtii it was more typical for older women.
In addition, there was a fairly significant correlation between the levels of the former and the amount of collagen in the skin. Now it is interesting to ask a typical question:What came first the chicken or the egg? The authors of the study are not sure A. acne promotes collagen synthesis or the other two proliferate with a decrease in collagen. Either way, there seems to be a correlation, but you have to look for causality. And besides, your research should be peer-reviewed so that its conclusions are taken into account to a greater extent. If all goes well, perhaps in the future this discovery can be used to improve anti-aging treatments. But this is still a long way off.
Meanwhile, the best thing left for us is to protect ourselves from the sun and avoid habits like smoking or drinking alcohol. Creams with hyaluronic acid can also be useful, especially for fine wrinkles, but there are no miracles when it comes to wrinkles. Well, not with this and nothing.
