Is it possible to control only the bad bacteria on the skin and increase only the good bacteria and skin-beautifying bacteria by skin care?

In modern science

1. “Cannot or cannot classify all indigenous bacteria in the human body into good and evil”

2. “There is no technology that can classify the same creatures into good and evil and control or reduce only one, or grow or increase only one.”

There is that.

It is said that many bacteria inhabit our skin, including those that have not yet been named.

In the latest modern science, the identification of bacteria that cause troubles among the indigenous skin flora is progressing, but the classification of all good and bad bacteria that are indigenous to the skin, including those without names, is progressing. The fact is that it is not actually done.

In the case of skin, even indigenous bacteria that are considered to be good may have a bad effect depending on the situation (also called opportunistic bacteria), and conversely, indigenous bacteria that are described as bad are also invaded by bacteria from the outside. It has not been scientifically denied that it may work well, such as suppressing indigenous bacteria, that is, there is no evidence and details have not been studied or elucidated regarding the judgment of good or bad of all indigenous bacteria.

Next, bacteria are classified into gram-positive bacteria, gram-negative bacteria, fungi, etc., not as good bacteria or bad bacteria, but the latest technology to sort the same organisms into good and bad. The point is that there is no such thing.

Like humans and animals, insects and living things, if you use “poisonous drugs”, “insecticides” and “bactericidal agents”, you can make good and bad people, good animals and bad animals, beneficial insects and pests, the human body. The indigenous bacteria that form, the bacteria and viruses, the good bacteria and the bad bacteria “act on both at the same time”.

The reverse is also true, and the recent boom in lactic acid bacteria has increased the attention of “bacteria” in the beauty world, but focusing on “good bacteria” and “skin-beautifying bacteria” that have a positive effect on the human body, the “good bacteria” Even if you want to grow or increase “skin-beautifying bacteria”, “all bacteria including bad bacteria” will increase at the same time.

In addition, humans and animals have acquired the physiological function of secreting the sebum necessary to protect their skin and maintain their health in the process of evolution. The sebum secreted by the sweat glands contains components that maintain the optimum pH value of each person’s skin and balance the indigenous bacteria on the skin.

It is called fatty acid, and it is a component that is abundant in human sebum, vegetable oils such as olive oil, and animal oils. Therefore, there are cosmetics all over the world that contain plant and animal oils containing these fatty acids, with the expectation that they will supplement sebum and keep the skin in good condition.

However, whether the fatty acids, which are the constituents of sebum, suppress “bad bacteria” such as Staphylococcus aureus and dominate “good bacteria” and “skin-beautifying bacteria” such as epidermal staphylococci, is the original question. Basic physiological functions of humans and animals to keep the skin weakly acidic and balance the indigenous bacteria (same as “saliva” that keeps the mouth weakly acidic and keeps the balance of indigenous bacteria) Therefore, it is quite natural to suppress “bad bacteria” and make “good bacteria” and “skin-beautifying bacteria” dominant. (If this is not the case, the skin will be full of “bad bacteria” and cause skin problems.)

Furthermore, by applying cosmetics containing fatty acids and plant / animal oils that are nutrients for all bacteria on the skin, why only “bad bacteria” are reduced and why only “good bacteria” and “skin-beautifying bacteria” are increased. It has been considered that there is little scientific basis for the mechanism of action, such as whether or not it will occur, and it is difficult to obtain actual clinical effects.

In addition, the sebum components of each person in the world and the optimal fatty acid composition for each person are different, and the composition of indigenous bacteria on the skin is also different for each person. Therefore, even if the fatty acids contained in the sebum are given to the skin (for example, mouth). (In the case of inside, even if the ingredients contained in saliva are added to the oral cavity), it means that “bad bacteria” will decrease and “good bacteria” and “skin-beautifying bacteria” will increase in common with each person. , There was a problem that it was not academically realistic in the study of flora.

(However, our research team also considers that fatty acids are highly useful for the skin, and researched BODYPEACE Premium Hand Care Cream as a skin care product that supplements the function of sebum and contains many beauty ingredients from around the world that are rich in fatty acids.・ Developed.)

The following is what is currently known in the world’s most advanced lactic acid bacteria research regarding the antibacterial peptide bacteriocin, which can select and control only one type of bacteria.

It is the antibacterial substances, antibacterial peptides, and bacteriocins produced by lactic acid bacteria that produce antibacterial peptides that control bacteria that are enemies to you and your friends (harmless to yourself and your friends) because lactic acid bacteria, which are living organisms, propagate. is.

The antibacterial substances, antibacterial peptides, and bacteriocins produced by lactic acid bacteria vary depending on the type, but there are many that have a narrow to wide antibacterial spectrum (range).

For example, the world’s first and most famous “Nisin A” has the widest antibacterial spectrum of lactic acid bacteria bacteriophages and controls most Gram-positive bacteria.

On the other hand, bacteriocins with a narrow antibacterial spectrum control only specific Gram-positive bacteria (Gram-positive bacteria closely related to the producing bacteria).

It can be said that “a certain bacterium or bacteriocin selects and controls a specific bad bacterium”, but unfortunately it also acts on a closely related gram-positive bacterium. I will.

Staphylococcus aureus “only”, which is considered to be a bad bacterium, has not yet been discovered in the world as a bacterium, substance, or bacteriocin that has a “single action”.

It is impossible to get rid of only “bad bacteria” among all the bacteria.

On the contrary, it is impossible to nourish and give superiority to “good bacteria”, “skin-beautifying bacteria” and “only”, and to increase “good bacteria”, “skin-beautifying bacteria” and “only”.

By knowing and paying attention to the existence and action of “good bacteria” and “skin-beautifying bacteria” on the skin, and growing and increasing “good bacteria” and “skin-beautifying bacteria”, we can understand the desire to seek beauty and moisturizing effects. However, unfortunately, it also increases “bad bacteria” at the same time.

For example, if nutrients such as “oligosaccharides” and “dietary fiber” that lactic acid bacteria prefer are given to “good bacteria” and “skin-beautifying bacteria”, they will also be nourishing to “bad bacteria”, and “good bacteria” and “skin-beautifying bacteria” At the same time, “bad bacteria” can increase in the same way.

It is actually difficult to establish new bacteria such as “good bacteria” and “skin-beautifying bacteria” on the human body, and it is not possible to nourish only the “good bacteria” and “skin-beautifying bacteria” that are indigenous to each person. What you can’t do is that the flora, which is composed of “good bacteria,” “skin-beautifying bacteria,” “bad bacteria,” etc., does not change, and if you give nutrition, the “bad bacteria,” which have relatively strong power, will also become healthy. It is possible that the power will expand further.

In other words, the human body’s “selecting and controlling only bad bacteria” and “increasing only good bacteria and skin-beautifying bacteria” cannot be realized by the latest science and technology.

The creatures on the earth are the same as human beings, but each of them supports, complements, acts, lives, and coexists in a balanced manner.

Not all of them exist meaninglessly, and in a situation where science has not advanced the elucidation of their functions and interactions, it is a fact that everything cannot be distinguished from good and evil, and superior and inferior. is.

In addition, even for the same human being, research results have been reported that the bacterial composition on the skin differs depending on the race, family, and each person depending on the genetics and living environment, and it is good for each person to have more than hundreds of species of indigenous skin flora. It can be said that it is not possible to distinguish between bacteria and bad bacteria.

The bacteria and flora that we have in our skin and intestines are not all that we have from birth, but from parents who have the same genes by rubbing their cheeks and contacting saliva since they were infants and live in the same environment. It is a fungus or flora that is inherited, and it can be said that the optimal bacterial composition genetically and environmentally for each individual protects the body.

Like human beings, creatures have good and bad points for a specific person or society, but they are born and exist because they are necessary, and they live and coexist with their individuality.

Invisible to our eyes, it is the same with bacteria, which are the same organism.

The problem with the skin is that Staphylococcus aureus and P. acnes, which are one of the bacteria that live on the skin as indigenous skin bacteria and do not usually cause problems (something useful), “excessively increase”. It is caused by waking up.

Our research team is conducting research to keep bare skin in a healthy and peaceful state by safely approaching bacteria that exist as indigenous bacteria on the skin but cause problems “too much” due to trouble.
