Currently, type A botulinum toxin preparations are becoming more widespread in aesthetic medicine. The most famous of them are certified in the Russian Federation: Botox (USA), Dysport (France), Xeomin (Germany), Lantox (China), Relatox (Russia). Injections of these drugs are a safe and highly effective method for eliminating wrinkles.
What is the mechanism of action of type A botulinum toxins?
The principle of action of type A botulinum toxins is to block the neuromuscular transmission, which leads to temporary muscle relaxation. This process occurs due to the penetration of botulinum toxins into the presynaptic nerve ending and impaired release of acetylcholine, a neurotransmitter, from which the transmission of a nerve impulse is carried out. Thus, the muscle does not receive a signal for contraction, it relaxes, and the skin above it is smoothed.
The use of Botox in neurology
Initially, botulinum toxins were developed for use in neurology. They are widely used to treat diseases such as cerebral palsy, tics of various localization, tremors of limbs and head, headaches caused by muscle tension of pericranial muscles, migraines, spastic paralysis, torticollis and many other diseases associated with muscle spasm. These drugs are indispensable in pediatric neurology. The aesthetic effect of botulinum toxins in the form of smoothing wrinkles was discovered by chance, as a side effect in the treatment of neurological diseases.
How is the Botox administration procedure performed?
The zone of necessary correction is determined, the muscles responsible for the appearance of facial wrinkles or folds, the required dose of the drug, injection points.
Several injections are made in the area of the desired muscle. At the same time, injections are practically painless and do not bring any discomfort. After the procedure, there are no traces of injections left.
Detailed recommendations are given after the procedure.
The clinical effect begins to manifest itself gradually, 3-5 days after the injection, finally increasing by day 14 and lasts about 4-6 months. The duration of the effect depends on the strength of the muscle, the dose of the drug, individual sensitivity and regenerative abilities of the body, as well as compliance with post-treatment recommendations. It is noted that the effect of Botox is significantly reduced with prolonged exposure to the sun, abuse of thermal and hardware procedures on the face, prolonged use of antibiotics, anesthesia.
The calculation of the dose of the drug administered depends on the gender, age of the patient, the severity of wrinkles, the proposed area of correction. For example, on average, for the correction of wrinkles in the forehead, nose bridge and corners of the eyes, about 35-40 units of Botox or 110-120 units of disport are needed (approximate ratio 1: 3).
Warning! Statistically, in 3% of patients there is an individual immunity to the drugs of this group, that is, the effect of the introduction of botulinum toxins may not be.

The main indications for the use of Botox
Mimic wrinkles on the forehead (Botox on the forehead)
Botox in the forehead, forehead wrinkle correction with Botox
Botox in the forehead is one of the most frequent correction areas, but at the same time the most difficult. Due to the relaxation of the frontal muscle, it is possible to smooth out horizontal facial wrinkles in the forehead and get rid of the habit of wrinkling any. The effect is usually very bright, which delights patients. Today, we are moving away from the standards of a completely immobilized forehead and partially retaining facial expressions, including the movement of eyebrows.
Separately, we note that the greatest number of complications after the introduction of Botox is associated with the forehead zone. First of all, it is the omission of the eyelids. As a rule, it occurs in violation of the injection technique, improper selection of patients, an excessive dose of the drug. With a pronounced excess of skin in the forehead and very deep wrinkles, patients reflexively wrinkle their forehead, thus trying to raise their eyebrows.
When muscles are relaxed in the forehead, in such cases, smoothing of the “skin accordion” and overhanging of the eyelids occur. Therefore, to start correcting this area after 50 years, as a rule, in 50% of cases it is no longer recommended. In such cases, we recommend that you pay attention to the procedure for filling wrinkles with the help of preparations based on hyaluronic acid.
Botox is also powerless in the treatment of compression wrinkles that occur not when the muscles work, but with prolonged compression of the skin in a certain position. For example, with vertical oblique wrinkles on the forehead, appearing when sleeping on the side.
Recommended dose for forehead:
Botox 5-15 units, Dysport 20-40 units.
Botox in the nose allows you to get rid of vertical wrinkles between the eyebrows, giving a frown.
