How many units of Botox for forehead?
Today, there are many different procedures for visual rejuvenation and giving the face a fresh and rested look.
One of the most common ways that everyone “on hearing” is Botox injections.
Introduction to the drug
Botox (botulinum toxin) is a specially processed and weakened neurotoxin type A and some other protein compounds, which is used in modern cosmetology for non-surgical removal of wrinkles.
Botox can be used in any area of the face and body. Once in the body, the compound breaks down to a pure neurotoxin, which blocks neuromuscular transmission of impulses.
In addition to cosmetology, Botox is used for therapeutic purposes – to relieve painful spasm, strabismus, nervous tick, and cerebral palsy.
Most wrinkles on the face are caused by facial movements. Some of them we can not even notice, because muscles make micro-movements or are in constant tension.
Neurotoxin allows you to relieve muscle tension, whereby the depth of wrinkles is significantly reduced and has a preventive effect on the appearance of new skin defects.
The validity of Botox lasts about 6-8 months. The drug temporarily accumulates at the site of administration, and then enters the systemic circulation. It is excreted through the urinary tract.
The drug does not have a General effect on the body and does not penetrate the brain.
General application rules
The dosage is individual for each patient. It is determined not only by the type of problem solved during the procedure but also by the characteristics of his body: skin type, age, and even sex.
Only a specialist with higher medical education can be engaged in the selection of dosage – in the context of cosmetic procedures, they can be a dermatologist, cosmetologist or plastic surgeon.
The dosage is not selected “by eye”. This requires a special procedure, which takes place in several stages. During them, the following actions are performed:
- Primary introduction in low doses.
- Repeated injection in 1-2 weeks. When re-visiting the doctor should assess the effect, the absence of side effects and well-being of the patient. If the drug is well received by the body, the patient is administered additional doses, correcting the original result.
- Maintenance injections are performed every 6-12 months. Each time the doctor evaluates the duration of preservation of the result, its effectiveness, and also makes sure of the normal reaction of the patient.
In between visits to the doctor the patient notices a sharp deterioration of health or local symptoms (rash, skin color change, education) which the doctor did not warn about, he should immediately seek medical help from the emergency service or his treating specialist.
If the dosage is chosen incorrectly, there may be two scenarios.
With too small a dosage, the patient simply does not see the expected effect.
Much more dangerous is too high a dosage-the muscles of the face can bind the “mask”, the face will completely lose elasticity and the possibility of muscle contraction until the complete withdrawal of the drug from the body.
Do not forget about the possible development of allergies to the drug. It should be tested in a small dose to avoid the development of anaphylactic shock in the patient.
When visiting a specialist, the patient should be warned whether he is doing the procedure for the first time or has previously received Botox injections. This is important information, because the initial administration, the dosage is always greater than the re-use.

Features of calculation
Botox is a trade name produced by Allergan. For this drug has its own dosing system, which is not identical to the usual for all milligrams and milliliters.
The quantity of a substance determined in the course of its tests according to the international system of biological activity is the units of a substance.
Human administration of about 3000 units of the drug is a lethal dose. Units of different analogs with botulinum toxin vary in volume and depend on the results of laboratory tests of each of the compounds.
One bottle of the product contains 100 units. Before use, the product is diluted in saline.
The calculation for one injection is made from the number of pure Botox units. The rejuvenation of different areas requires approximately the following amount of substance:
- at one point the injection takes 1-2 units;
- horizontal wrinkles in the forehead area-15-25 units;
- wrinkles in the brow area-10-25 units.
The dosage is calculated, taking into account the characteristics of the body, as well as the type and condition of the skin – for thin and dry skin requires less preparation than for oily, and women need less than men.
Stages of the procedure
For the procedure, the patient requires some special training. For 3 days before the session, you can not take alcohol, for the day to avoid excessive physical activity, as well as take any dosage forms that prevent blood clotting.
During the course of antibiotics also can not be administered botulinum toxin. It is also undesirable to perform the procedure during menstruation.
It should be borne in mind that from 1 to 3 days after the session on the face there will be traces of injections, small bruises, and a small swelling. Such a reaction of the skin is considered the norm, however, for this reason, it is desirable to carry out the procedure before the weekend.
Also, the effect will be most noticeable only 2 weeks after the procedure – this should be borne in mind if the procedure is planned before any important event.
The procedure includes the following steps:
- In the office of the cosmetologist, the patient is asked to depict various facial movements to determine the areas of maximum muscle activity.
- After that, the specialist marks the injection site. It is important to ask the patient about the presence of allergies to drugs and systemic diseases before administration. If everything is in order, you can begin to dilute the drug.
- The solution is injected with an insulin syringe with a fixed needle. The needle is very small in diameter, so it minimally damages the skin in places punctures.
- The skin is pre-treated with an antiseptic solution. Injection point is performed at short intervals from one another. The average for getting rid of wrinkles in the area of the forehead or between the eyebrows will take about 10-15 shots.
For at least five hours after the session, the patient is forbidden:
- Bend over and put your face down
- long lie
- take a hot bath and steam
- to stay out of the sun
- massage the injection site with your hands
- drink alcohol (at least three days after the procedure
The effect becomes noticeable approximately 48 hours after the injection, however, the maximum result is achieved only at the end of the second week, when the Botox is completely spread over the tissues and smoothes the muscles.
The effect of the drug lasts an average of 6-8 months, however, it depends on the characteristics of the metabolism of each individual patient.
The term can range from 4 months to a year. Typically, older patients experience a relatively long-term effect.
In addition, from procedure to procedure, the drug accumulates in the body, and each time to achieve the effect requires a smaller dose.
Maintenance injections are made approximately every 6-8 months. However, as already mentioned, in some patients the effect lasts longer, so the need for a new dose of the drug occurs much later.
