WHY ANESTHETIC CREAMS ARE NEEDED
Each person has an individual pain threshold, and often clients ask if something can be used to anesthetize the process. Some artists and salons offer local anesthesia, aka application anesthesia. These are various gels, ointments, and sprays that contain anesthetics in their composition. They do not get rid of the pain completely, but in some cases reduce the discomfort.
Local anesthetics are medications that cause local desensitization, the effect does not extend to deep tissues. Such agents are widely used, for example, in dentistry.
HOW IT WORKS
To be clear about what causes the effect of pain relief, it is worth understanding why we feel pain in the first place. Sensory nerve endings transmit sensations to the central nervous system via nerve fibers. This happens by generating an electrical impulse. Any irritation of the nerve endings, be it pressure, incision, temperature, or something else, spreads excitement due to the wave-like movement of sodium ions in and out of the cell. When an irritation exceeds a sensitivity threshold that is individualized for each person, the person feels pain.
Pain is a reaction, which informs about potential danger for the body, as there is some harmful effect on the body. That is, if we touch something very hot with our hand and get burned, we immediately reflexively pull it away from the source of pain. But in the case of a procedure, be it a medical procedure or a tattoo, it has to be tolerated or suppressed - depending on the intensity of the irritant.
