BODYPEACE Premium Hand Care Cream contains “Neonisin-e ® ︎” (cleaning aid), a bacteriocin preparation that is a highly purified antibacterial peptide produced by lactic acid bacteria, Nisin A.
For details on the challenges and challenges of research institutes around the world regarding the clinical effects of trying to add lactic acid bacteria to skin care products, please visit the “Neonisin” website.
In addition, there was a big problem when using lactic acid bacteria in skin products and cosmetics.
The big issue is that “a product that combines lactic acid bacteria with preservatives and synthetic fungicides cannot be established.”
Preservatives such as paraben, phenoxyethanol, alcohol (ethanol), BG (butylene glycol), sodium benzoate, K sorbic acid, grapefruit seed oil, acid, various synthetic fungicides, and antibacterial substances such as lactic acid bacterium bacteriocin are used. This is because it is a bactericidal agent for sterilizing bacteria that are organisms and preserving the product, and it also sterilizes lactic acid bacteria that are the organisms that are mixed together.
In addition, glycerin and other plant extracts, essential oils and fragrances, and fermented liquids of other bacteria, which are mixed together as cosmetics, kill lactic acid bacteria.
When making skin care products and cosmetics that can be stored and used at room temperature instead of refrigerating like yogurt, lactic acid bacteria will rot at room temperature if they are alive, so it is necessary to sterilize them in order to distribute them as products. It becomes.
Therefore, preservatives such as paraben, phenoxyethanol, alcohol (ethanol), BG (butylene glycol), sodium benzoate, sorbic acid K, grapefruit seed oil, acid, and alcohol (ethanol) are included in the products so that they can be stored at room temperature and distributed at room temperature. ) And other bactericides are added, but at that point the lactic acid bacteria, which are living organisms, are killed.
For enterobacteria, there are research reports that killed lactic acid bacteria can also serve as food for enterobacteria and may be useful, but there is an academic presentation of research results that even if dead bacteria are applied on the skin, there is some effect. The reality is that there isn’t.
If you think that the lactic acid bacterium culture component may be good for your skin even if the lactic acid bacterium is killed, you can expect the “glycerin (moisturizing component)” produced by the lactic acid bacterium.
In that case, a higher moisturizing effect can be obtained by applying high-purity glycerin itself to the skin instead of the culture component containing a small amount of glycerin produced by lactic acid bacteria and containing a large amount of impurities.
Also, if it contains live lactic acid bacteria such as yogurt and lactic acid bacteria beverages, even skin products and cosmetics are distributed and sold in a refrigerated state, and even for home use, they are stored daily in the refrigerator for about a week. If it is a product that sets a limit expiration date, I think that lactic acid bacteria can be delivered to the skin alive.
Even if it is a living lactic acid bacterium, the clinical effect when applied to the skin varies depending on the situation, the amount of peptides and glycerin produced is unstable, it takes time to produce, and it has a clinical effect as a cosmetic product. The current situation is that expectations are not realistic.
It is how you can change your skin by applying yogurt containing lactic acid bacteria such as bifidobacteria and skin-beautifying bacteria that lived at home, or the yogurt that has been heated to kill the lactic acid bacteria. You can see if you try to do it.
Yogurt has been popular as an edible product all over the world since ancient times, but I think there is a reason why it has not been used for beauty since ancient times.
Therefore, products that can be stored at room temperature that contain both lactic acid bacteria and preservatives, products that contain both lactic acid bacteria and bactericides at the same time, and products that contain lactic acid bacteria culture ingredients should contain lactic acid bacteria that evoke the effects. It will be, but
Actually, it depends on preservatives such as paraben, phenoxyethanol, alcohol (ethanol), BG (butylene glycol), sodium benzoate, sorbic acid K, grapefruit seed oil, acid, and bactericidal components such as alcohol (ethanol), antibacterial substances, and synthetic fungicides. The essential lactic acid bacteria have died (since they are dead, they can be stored and distributed at room temperature), and there have been major problems in clinical efficacy and commercialization.
For the above reasons, for BODYPEACE Premium Hand Care Cream, only high-purity “Neonisin-e ® ︎”, which is a highly purified antibacterial peptide bacteriocin produced by lactic acid bacteria, is used for the purpose of bacteriocin action. , It is formulated as “lactic acid bacterium culture extract” as the label name, and it is a formulation that does not contain “lactic acid bacterium itself” or “living lactic acid bacterium” which cannot be expected as a clinical effect.
If you like beauty with live lactic acid bacteria, we would appreciate it if you could try applying the bacteria to your own skin using a commercially available yogurt or yogurt making machine.
