Each year, the market of aesthetic medicine provides more and more cosmetic procedures, but despite this, injection methods still remain the most popular. In this regard, drug manufacturers, as well as the doctors themselves, strive to provide the patient with absolute comfort during the correction, and pain relief is of no small importance.
Choice of local anesthetic – this is not an easy task, on which not only the patient's feelings, but also the comfort of the doctor himself depend. Read about which drugs have the best analgesic effect on estet-portal.com in this article.
The role of local anesthesia in aesthetic medicine
Local anesthesia in aesthetic medicine is needed for both physical and psychological comfort of the patient.
The absence of pain changes the attitude of patients towards beauty procedures, and they decide on them with greater confidence.
Modern manufacturers of injectables, such as Allergan, pay special attention to pain relief. Therefore, JUVÉDERM® They already contain lidocaine. This eliminates the need for the additional use of a local anesthetic, making the procedure virtually painless.
Mechanism of action of local anesthetics
Local anesthetics are expected to stabilize the membrane at resting potential, increase the threshold for electrical excitation, and decrease the propagation of the excitatory impulse, thereby blocking nerve conduction. There is a theory that the pain impulse travels along small, unmyelinated nerve fibers (C-fibers), which are more sensitive to the action of local anesthetics compared to larger fibers that are responsible for transmitting other sensations. Therefore, patients can feel pressure and vibration, becoming insensitive to pain.
The main rules for painless injection of fillers
In order for pain relief to be as effective as possible, the doctor, in addition to using local anesthetics during injection, should be guided by a few simple rules:
• use a small-diameter needle for correction, as it injures the tissues less;
• needle must be driven slowly in order to stimulate pain receptors to a lesser extent;
• To reduce pain due to tissue stretching under the pressure of the filler, the drug must be administered gradually.
In addition to the injection technique, psychological comfort during the procedure plays a special role. In this connection, the doctor needs to both tune himself in a positive way, and give confidence to his patient.

Peculiarities of using local anesthesia during injection correction
There is a lot of conflicting information on the Internet regarding the use of local anesthesia during injection correction.
Some sources state that doctors should refuse anesthesia altogether, others emphasize the preliminary use of anesthesia, and still others – they say that dermal fillers, which already include a local anesthetic, have the best effect. What to believe?
The lack of anesthesia causes discomfort not only to the patient, but also to the doctor, who finds it more difficult to control the administration of the drug.
Preparations that contain lidocaine, such as JUVÉDERM® from company "Allergan", provide a comfortable introduction due to high-quality anesthesia, and also avoid additional punctures for the introduction of anesthetic.
