Many training teachers teach students to use normal saline for anti-inflammatory, cleansing and disinfection. In fact, this is a very serious mistake, and many people still don’t understand it. They even regard this as a basic operation and standard method, which will cause the eyebrows to not be colored or even worse. The occurrence of the problem, to a certain extent, also reflects the chaos in the current tattoo training market, otherwise it would not make such a joke.
Everyone uses normal saline to soak cotton pads and wipe the operating parts. They think this can have a sterilization and anti-inflammatory effect, but in fact it may be very different from your knowledge.
Physiological saline does not have the effect of sterilization, and normal saline may affect the coloring.
Physiological saline is 0.9% sodium chloride aqueous solution, because its osmotic pressure value is about the same as that of normal human plasma and tissue fluid, so it can be used for rehydration (it will not reduce and increase the sodium ion concentration in normal human body) and other For medical purposes, it is also often used for culturing living tissues and cells in vitro. It is the concentration of the liquid environment where human cells are located.
In this case, it is not difficult for us to understand why normal saline can not be sterilized and anti-inflammatory. Since harmful bacteria can survive and multiply in our wound environment, it is not difficult to survive in a similar environment, and we still think that it can Kill germs?
We can understand that physiological saline is to some extent tissue fluid, and in the category of tattoos, tissue fluid and blood are also inseparable to some extent. Because no matter whether it is bleeding or tissue fluid during operation, these fluids will affect our coloring more or less. This should not be difficult to understand. Since both of these can affect our coloring, then you use Wiping the eyebrows with saline is equivalent to applying tissue fluid on them. In this way, you can experience it yourself, can the coloring be affected?
When wiping the wound with a cotton pad soaked in physiological saline, it will soften the cutin. The color material that was originally attached to the cuticle is taken away along with the cutin when it is wiped. So many students go through the needle and wipe it again, but the eyebrows are still not colored, which is the reason.
