Due to the increased demand for facial rejuvenation using non-invasive technologies, many experienced doctors using onabotulinum toxin A have taken aim at the upper part of the face as well. At the moment, such treatment has not yet been approved by the FDA, so doctors perform it at their own peril and risk. Doctors performing such procedures should have a good understanding of the process of raising and lowering the facial muscles, because the reaction of the facial muscles of the lower part of the face can be more complex than the reaction of the muscles of the middle or upper part of it.
In this article, we will tell about the features of onabutolotoxin A in cosmetology.

Onabotulinum toxin A: upper vs lower face
There are a number of factors that cause anatomical difference between the upper and lower parts of the face, which will affect the process of injecting ona botulinum toxin A for facial rejuvenation.

The skin of the upper part of the face is thicker and adheres more to the mimic muscles. As a rule, much higher doses of onabotulinum toxin A are used for the upper face, plus, in this area, the toxin rarely leads to functional imbalance. The territorial location and indistinct boundaries of the lower and middle parts of the face are the reasons why smaller doses of ona botulinum toxin A are needed for their treatment in order to gently attenuate muscle activity and avoid diffusion. Wrinkles in the middle and lower parts of the face are more static in nature than wrinkles in the upper part of the face that are dynamic in origin.
In order to preserve the functionality and anatomical balance of the middle and lower parts of the face during treatment with onabotulinum toxin A injections, exceptional precision is required – minimum volumes of small doses of the drug must be injected exactly into the designated muscle!
The muscles that lift the upper lip are easily affected by even the slightest diffusion of onabotulinum toxin A, which will instantly lead to a violation of one or more motor functions of the lips. Since the orbicularis oculi muscle intersects with the levator fibers of the upper lip, injections of onabotulinum toxin A should only be administered by an expert in this field.

In many areas of the midface, the best cosmetic results can be achieved with various fillers or other invasive procedures, and ona botulinum toxin A can be used to improve the effect of these procedures, as well as to prolong the final aesthetic results.
Onabotulinumtoxin A for nasal alar inflation
Some people in everyday life or under the influence of physical or emotional stress tend to inflate the wings of the nose and constantly expand the nasal aperture during inspiration. People with a broad bridge of the nose and a wide base of the alar nostrils may have well developed muscles of the distal part of the nose, which allows them to inflate the nostrils both intentionally and involuntarily.
Practical skills for safe and effective contouring
Functional Anatomy
Inflation of the wings of the nose – this is the result of an involuntary contraction of the lower part of the nasal muscle, the alar part of the nasal muscle (dilator of the nostrils), which causes the wings of the nose to periodically swell. In some people, the middle portion of the levator lip and alar of the nose pulls the crus of the lateral cartilage of the nose up, shifting the line around the alar of the nose to the side and flaring the nostrils.
Dosage of onabotulinumtoxin A for nasal alar inflation
The patient, in a sitting or reclining position, is given a subcutaneous injection of 4-10 units of onabotulinum toxin A into the center of each alae towards the alae rim along the lateral roots of the alae.
This will loosen the involuntary contractions of the nostril muscles. Such results may be useful in ethnic groups that have a characteristically broad bridge of the nose and broad alar noses that expand easily due to the hyperkinetic alar nasalis muscle. It is worth noting that only those patients who consciously and actively inflate their nostrils are candidates for injections of onabotulinum toxin A.
Results of using onabotulinum toxin A in flaring of the alae
In patients who may deliberately cause nostril flaring, injections of onabotulinumtoxin A reduce the anterior diameter of the nostril, thereby visually constricting the nose without obstructing inhalation. The results last up to 3-4 months, and even longer with repeated procedures.
Complications
In the wrong patients, injections of onabotulinum toxin A may not be reflected in the results of the procedure, only money, time and effort will be wasted. Otherwise, these patients will not experience any particular complications other than those that often occur during transcutaneous injections – pain, swelling, redness, bruising. There is no evidence of inspiratory difficulty in patients treated with ona botulinum toxin A during nasal alar inflation.
