Technologies for facial correction through the introduction of fillers are constantly being improved and supplemented with new techniques. One of the most important areas in which new research is constantly being conducted is minimizing complications after the procedure, reducing trauma to the skin and reducing patient pain during the introduction of fillers.
One of the most common non-surgical methods for correcting age-related changes in the skin is currently the injection of fillers based on hyaluronic acid into it. Previously, these fillers were implanted under the skin using sharp surgical needles, which increased the incidence of side effects such as pain, bleeding, bruising, swelling, and inflammation.
In 2005, aesthetic medicine was replenished with a new revolutionary method of facial modeling – the technique of the so-called “soft filling”. The distinguishing feature of this technique was the use of a blunt cannula instead of the traditional pointed needle. Currently, the technique of facial correction, when fillers are introduced using cannulas, is considered one of the most advanced in its field and is approved by plastic surgeons around the world. It allows you to increase the volume of areas of the face to be treated, change the shape of the lips, and also fill in the wrinkles of the face and neck with minimal skin trauma.
However, the innovations in the field of face correction with fillers did not end there. Now experts suggest using such a technique for introducing fillers, in which the procedures are carried out with a limited number of injection points. This was made possible thanks to the use of non-traumatic flexible blunt needles and preparations based on hyaluronic acid with different viscosities and durability.
What are the benefits of the “single-pierce” technique
The first advantage of the new technique, perhaps, can be called the joy in the eyes of the patient when the doctor tells him about the features of the upcoming procedure and informs him that for face correction he will need to make only one or two injections on each side. With all the moral and physical readiness for the procedure, any patient is still afraid of pain and is very glad to know that its probability is minimized.
In addition, the technique of introducing fillers under the skin through one point and using flexible blunt needles has the following advantages:
- reducing the risk of bruising;
- minimizing the risk of developing inflammation and, consequently, rapid catabolism of the administered agent;
- no need for anesthesia;
- the opportunity for the patient to shorten the rehabilitation period as much as possible, not be afraid of swelling and bruising, and quickly return to an active social life.
About the features of the technique “one puncture” Mimi Ehrenreich, a dermatocosmetologist and surgeon from France, told the guests of the XIV International Symposium on Aesthetic Medicine about the methods of face correction in her report “Modern trends in facial modeling from one point. Softfil technique. New opportunities with minimal trauma”.
According to Mimi Ehrenreich, the innovative SoftFil technique for facial injection procedures is adapted to all types of hyaluronic acid and other fillers. It allows you to treat large areas of the face through one puncture, to distribute the filler in the skin harmoniously and uniformly, and to perform the procedure quickly and almost painlessly.
Injections for each area should be given at the specific depth needed to restore volume loss, correct wrinkles, or apply nappage. To achieve the best results, it is necessary to choose the most suitable type of hyaluronic acid preparation with the most adapted viscosity and durability.
The area to be treated, the depth of injection and the characteristics of the hyaluronic acid determine the selection of the correct injection point and the appropriate SoftFil needle. In order to treat the entire face, usually only 2-4 needle entry points are needed on each side. The rounded end of the needle allows you to control the depth of the injection, eliminating the risk of damage to large blood vessels or nerves.
Seven types of blunt SoftFil needles, differing in diameter and size, are specially marked, which helps to control the injection depth at any stage of the procedure, to find an excellent ratio between each injection point, each injection site, the viscosity of the selected hyaluronic acid preparation. The needle is inserted under the skin through a puncture made with a pointed needle of the same diameter.
In addition to the presentation, Mimi Ehrenreich, MD, demonstrated the SoftFil technique in a master class on facial modeling using the "one point" technique.
It is very important to properly asepsis the skin, as the SoftFil needles pass close under the skin. Next, it is necessary to analyze the condition of the face, skin, muscles, make marking of depression zones and relief zones with a pencil in order to clearly see where and how much filler to inject. Then you need to determine the injection points depending on the zones of the necessary correction.
Preliminarily, an injection is made into the skin with a regular pointed needle, for example 27G. The rounded tip of the SoftFil needle is gently placed in the puncture made by the previous needle while stretching the skin with the other hand. The needle easily passes under the skin at the level of the papillary or reticular dermis, without damaging the tissues and walls of blood vessels and without any effort on the part of the doctor. One must always manipulate the needle gently, and it will easily reach the desired areas.
Thanks to the use of SoftFil needles and the technique of introducing the filler from one injection point, the likelihood of complications after the procedure is minimized, and patient satisfaction is significantly increased when modeling the face with fillers.
