The level of anesthesia that is achieved depends on several factors. They include:
- the product, the brand, and the ingredients the product contains;
- the level of pain tolerance of the client - which will vary from person to person;
- absorption of the anesthetic in the skin – another variable;
- the procedure used to apply the anesthetic – depends on the practitioner;
- the management of the client, in which the trust generated facilitates relaxation and fluid workflow.
Of course, there are several factors beyond the anesthetic itself which influence how the patient handles the procedure.
FACTS YOU SHOULD KNOW:
To do permanent makeup, regardless of the technique used, topical anesthetics (applied superficially on the skin) are much safer than injectables. When an intradermal anesthetic is injected, the risks of inflammation, bleeding, and migration of the pigment increase. Additionally, the injection of anesthetic into the skin is limited to medical personnel.
Topical anesthetics are available in many pharmaceutical forms that include gels, creams, ointments, lotions, and sprays.
Mechanism of action:
Topical anesthetics reversibly block nerve conduction near the site of administration, producing a temporary elimination of pain sensation in a limited area.
The nerve impulse conduction is blocked by decreasing the permeability of the nerve cell membrane to sodium ions, competing with the calcium binding sites that control sodium permeability. This change in permeability results in a decrease in depolarization and an increase in the threshold of excitability. This ultimately prevents the action potential of the nerve from transmitting the sensation of pain from the skin to the brain.
Most anesthetic agents that exist as solids are absorbed superficially through intact skin.
The beginning of the action is fast, with an initial response obtained in approximately 1 minute and an effect that lasts approximately 15-20 minutes. Anesthetic agents are metabolized in the liver and their metabolites are excreted by the kidneys. They should be used in small doses.
- Use a micro-brush for the application of topical anesthetics. Avoid the use of cotton swabs, because they absorb the anesthetic. The micro-brush allows facilitates a precise and controlled application of the anesthetic, especially in the area of the eyes.
- The concentration of the topical anesthetic is key. For eye makeup procedures, concentrations of 3-5% lidocaine are recommended. Higher concentrations can interfere with the fixation of the pigment. Furthermore, they are exclusive to medical professionals for use in other types of procedures.
- Do not apply too much anesthetic and do not apply it in advance of the procedure. Excessive application and prolonged wait time generate an effect opposite to the desired one. It is better to apply the product in minimum quantities several times than to apply too much in a single application.
- Do not let your client feel pain. Re-apply the product every time you make a pass with pigment.
- Do not ask your client if he or she feels pain. When you ask them if they feel pain, their mind immediately thinks about the pain. It is recommended that you ask them if they feel good, prompting them to think about feeling good.
Softap offers two types of topical anesthetics: Block Aid and Minnerva II.
A combination of the two products facilitates a greater anesthetic effect while producing vasoconstriction, which reduces the risk of bleeding.
