Prevention of infection in the micropigmentation room: disinfection standards

How to Prevent the Transmission of Infectious Microorganisms in the PM Room

“I know that disinfectants need to be changed from time to time. Are there any rules or regulations on how often this is done? This question sooner or later arises in every permanent makeup artist.

Microorganisms, especially pathogenic and opportunistic pathogens, have the ability to adapt to environmental conditions, to the factors that affect them. And among these microbes are the causative agents of infectious diseases, including the so-called nosocomial infections, as well as infectious diseases associated with the provision of cosmetic services, and this is a huge list of harmful microorganisms. Let us recall only a few: Staphylococcus aureus, Streptococcus, Escherichia coli, Pseudomonas aeruginosa, pneumococci, Proteus, Klebsiella, Salmonella, Bacteroides, Clostridia, fungi of the genus Candida and many others that bring trouble.

Protective Measures

The use of disinfectants to destroy such microorganisms is one of the important measures to protect both working craftsmen and their clients from infectious complications that may occur in cases of violation of the anti-epidemic regime. But one of the prerequisites for effective protection when using a disinfectant is its ability to destroy infectious agents. As both scientific research and practice show, by the end of the 3-4th month of constant use, some microorganisms get used to many disinfectants. They survive and even continue to multiply, producing their own similar, already resistant (resistant) offspring to this disinfectant. If you continue to use the same product, there will be no effective disinfection. To do this, they undertake the method of periodic rotation of the disinfectant, that is, shifts. Moreover, such a replacement must be made not by the name of the disinfectant, but by the active substance. Of course, for this you need to understand which particular chemical group this or that disinfectant belongs to.

Chemical groups of disinfectants

In fact, there are not so many of them, and the most consumed today are based on aldehydes (glutaraldehyde, glyoxal, formaldehyde, succinic acid aldehyde, orthophthalic), with peroxide compounds (hydrogen peroxide, perborates, peroxyacetic and peracetic acids, chlorine dioxide), with surfactants (quaternary ammonium compounds, or QAS), tertiary amines, diamines), a group of guanidine derivatives (polyguanidines, biguanides), with an alcohol base (ethyl alcohol, isopropyl and propyl alcohols, aromatic alcohols), composite - a complex of compounds from various the listed groups.
