Cannulas can be considered a real revolution in the field of beauty. For contour plastics, this is a real find because they allow you to make the procedure for introducing fillers less painful.
What are cannulas and how do they differ from ordinary needles?
Contour plastic cannulas are tube-shaped needles that, unlike conventional ones, have a rounded blunt end. They are used to inject liquid fillers under the skin. If we talk about ordinary sharp needles, then they severely injure the skin, tearing the tissue. In addition, they often cause bruising and bruising.
Initially, flat needles were used during liposuction. They were big enough. But having thoroughly studied all the advantages of this type of needle, plastic surgeons considered it necessary to adapt them for more delicate procedures. So there were cannulas, which have the following distinctive features:
- minimum diameter;
- hollow inside;
- flexibility;
- blunt smooth tip;
- side hole.
Cannula in medicine
For the first time, French doctors resorted to using cannulas. This happened back in the 70s. Only then their sizes were reduced for use in cosmetology. For medical purposes, these types of cannulas are used:
- aspiratory (removing fluid from a wound);
- intravenous (catheterization of veins and infusion therapy);
- nasal (oxygen supply to the respiratory tract);
- ophthalmic (washing of the eyes and lacrimal canals);
- tracheostomy (improvement of air circulation in the trachea).
Features of use
Contouring cannulas are becoming increasingly popular. They are used as follows:
- first, the skin must be disinfected and lubricated with an anesthetic cream;
- further, using ordinary needles, punctures are made (the rounded end of the cannula does not allow to violate the integrity of the skin);
- a flexible needle is inserted into the hole, through which the filler is introduced;
- treated areas are gently massaged in order to ensure uniform distribution of the drug.
Main advantages
Contour plastic cannulas have a number of advantages. So, for starters, it’s worth mentioning flexibility. This allows you to move the needle under the skin, and therefore do not need to repeatedly violate the integrity of the skin in order to achieve the expected effect. So, to introduce the filler on the lips, it is enough to make one puncture in the corner. The same hole can be used to partially fill the space around the mouth and cheeks.
More and more fans are finding cannulas for contouring. A description of the benefits also contains information about the round, blunt needle tip. It does not tear tissue, which avoids pain, swelling and bruising. In addition, the cannula will not be able to pierce the vessel. Thus, the risk of filler getting into it is significantly reduced.
Injections in some areas of the face are associated with a high degree of risk. So, if we talk about the area around the eyes, minimizes side effects. The use of cannulas minimizes the risk of impaired blood flow and subsequent tissue necrosis. Speaking about the introduction of fillers under the circular muscles, the use of a rounded needle helps to avoid tissue rupture.
Classification and labeling
The cannula for contour plastics is becoming more widespread. The photo of the needle shows a specific, rounded tip shape. It is worth noting that cannulas can vary in length, diameter, and degree of elasticity. The appropriate marking will help to understand:
- 30G is used to introduce medium viscosity fillers. It is used to correct the area of the lips, nose bridge, as well as the temples and forehead. Suitable for intradermal injection.
- 27G is used for the introduction of fillers of medium and low viscosity. It is used to correct the nasolacrimal area, the line of the puppet, forehead, circles under the eyes, as well as defects on the skin of the hands. Suitable for shallow subcutaneous and intradermal injections.
- 25G is used to introduce high viscosity fillers. It is used to correct cheeks, wrinkles between the eyebrows, nasolabial folds, corners of the mouth, as well as the neckline and neck. Suitable for superficial injection.
- 22G is used to introduce high viscosity fillers. It is used to correct the shape of the cheekbones and cheeks, nasolabial wrinkles, as well as folds in the chin area. Suitable for medium and deep injections.
- 21G is used to introduce the most viscous fillers. It is used to correct the oval of the face, fill the cheekbones and form the contour of the lower jaw, nasolabial folds, as well as congenital and acquired defects. Suitable for deep insertion into the periosteum.

One of the most popular trends is the use of cannulas for contouring. What is it, every beautician who follows the latest in beauty knows. The cannulas of the following manufacturers have proven themselves best of all:

- TSK Laboratory is a popular Japanese cannula supplier. Experts managed to achieve the optimal alloy formula, as well as the perfect smoothness of the needle itself and its tip.
When is it better to use regular needles?
It is not always possible to use cannulas for contouring. The use of conventional needles is sometimes more appropriate. So, as an example, plastic lips. So, for example, to give the contours of the mouth a neat shape, small uniform portions are required, which can be entered only with a sharp needle. But cannulas are appropriate only if you need to give lips volume.
Often fillers are used to remove acne scars. Since it is necessary to introduce strictly limited doses, you need a thin needle with a sharp tip. Well, of course, you can’t sweep away the subjective moment. So, the specialist must undergo preliminary training in contour plastic cannula. In addition, stupid flexible needles are much more expensive than usual.
Contraindications
The use of cannulas, like conventional needles, has a number of contraindications. So, do not resort to contour plastic in the following cases:
- inflammatory processes in the area where it is planned to make a puncture;
- fungal infection;
- previously introduced filler, which has not yet been completely processed by the body;
- bleeding disorder;
- recent chemical or laser facial cleansing.
Positive reviews
A real innovation in the field of correction of appearance can be considered cannulas for contour plastics. Reviews note the following advantages of using this technique:
- minimal need for anesthesia during the procedure;
- lack of bruising, bruising and swelling;
- the duration of the rehabilitation period is significantly reduced;
- minimum pain and discomfort;
- the possibility of introducing filler in hard to reach places.
disadvantages
Of course, cannulas are becoming more and more popular among contouring plastics specialists as well as among their clients. However, flexible needles are not without drawbacks. These include:
- the procedure lasts much longer than in the case of ordinary sharp needles;
- safety and effectiveness of plastics are possible only if the specialist received the appropriate qualifications following the results of special training;
- filler consumption by 10-15% more, which increases the cost of the procedure;
- the use of such a technique requires good anatomical knowledge;
- filler can get into the deeper layers of the skin.
Cannulas are a new word in contouring. The use of such needles is much more effective.
