Cannula in cosmetology and medicine

The cannula, according to doctors, is a significant discovery of the 21st century in cosmetology and contouring. Recently, injection rejuvenation is gaining popularity. To make this procedure as comfortable as possible, experts have improved the traditional needle and created a cannula.

Cannula – what is it

Cannulas are hollow tubes with a side opening. Unlike ordinary needles, they have a blunt end, which avoids damage to the soft tissues and reduces the pain of the patient. Thanks to its flexibility, the cannula moves apart and bends around the vessels without injuring them.

The idea of bending blunt-pointed needles was proposed by a plastic surgeon from France Bernard Herzog in 2009. The first cannulas began to be used in plastic surgery to remove fatty tissue. Later, their advantage was also appreciated in cosmetology.

Cannula – application in cosmetology and contour plastic

Cannulas began to be used in cosmetology and contour plastics relatively recently. Beauticians note that when using a cannula, facial contours are more natural.

Due to its flexibility, the procedure is carried out with a minimum number of punctures, and the injection is administered as accurately as possible. But, according to experts, it is impossible to completely replace the needles with cannulas. Due to the blunt end, it cannot make a puncture in the skin, therefore it is carried out with a needle. It is also used in cases where it is necessary to make an injection with a stroke or close to the skin.

In cosmetology, with the help of cannulas, the face contour is leveled, age-related changes are eliminated, injections are made to moisturize the skin. In contour plastic, cannulas are used in procedures to eliminate sagging skin of the face, neck and decollete; increase and correction of individual sections; smoothing deep wrinkles.

The advantage of a cannula – which is better: needles or cannulas

The main advantage of the cannula is its flexibility. Due to this feature, it easily overcomes subcutaneous obstacles without violating their integrity.

An important factor is that cannulas reduce the likelihood of bruising and swelling, as aesthetics play a large role in cosmetology. Unlike traditional needles, cannulas allow the most accurate distribution of the substance under the skin. This gives cosmetologists the opportunity to achieve the most natural contours.

According to doctors, cannula injections are considered the safest. It is ideally suited for procedures performed in difficult to reach and sensitive areas, such as the neck, the superciliary arch, temples, cheekbones, nose bridge and the eye area.

Rejuvenation using a cannula is carried out through a minimum number of punctures, which makes the procedure almost painless and shortens the healing time.

If we compare cannulas with needles, then the former have a lot of advantages. But there are certain injections that cosmetologists prefer to make with needles. These include lip correction, the creation of thin or dashed lines.

INTERESTING FACT! Cannulas reduce the risk of bruising and swelling by 90%. Recovery time is reduced to a few days.

disadvantages

Despite the considerable list of advantages, the cannula is not without drawbacks. Among them:

1. High qualification requirements for a specialist. The procedure for injecting with a cannula is much more complicated compared to a needle, so a doctor needs to undergo preliminary training. The specialist needs to have an idea of the elementary arrangement of important vessels and be able to work on sensitive areas of the body.
2. High material consumption. On average, the amount of substance consumed increases by 15%. This is a significant minus, given the high price of cosmetics.
3. The increase in the cost of the procedure. In most cases, drugs are dispensed ready-made. In the kit an ordinary needle is attached to them. Cosmetic centers have to buy cannulas separately, and this leads to a rise in price of injections. Many patients do not accept additional costs.
4. Contraindications Cannulas are not prescribed in cases when the client does the procedure again, and the first injection was made with a needle. This is due to the fact that the needle violates the integrity of the tissues and during healing, micro-scars are formed through which the cannula will be difficult to pass.

Contraindications

It is undesirable to inject on inflamed skin. Patients suffering from skin diseases or with skin prone to scarring are also not recommended to use cannulas. It is contraindicated to carry out the procedure in areas after injections with collagen and hyaluronic acid.

Types and features of cannulas

Several types of cannulas should be considered, as this is not some standard tool. The cannulas differ from each other depending on the purpose.

Beauticians agree that only trained specialists can carry out procedures using cannulas.

IMPORTANT! Incorrect cannula injection can lead to an uneven distribution of the drug under the skin, vascular damage and swelling.

Procedure Algorithm:

1. Marking the treated area and drawing puncture points.
2. Disinfection and anesthesia.
3. Pre-puncture with a sharp needle.
4. The introduction of the cannula. In this case, the skin is stretched in the opposite direction from the movement of the needle.
5. Injection of the drug.
6. Massaging the treated area for proper distribution of the substance.

When to use regular needles

Cannulas are often used in contouring, but not all procedures can be performed using this device. The cannula is designed for uniform and linear administration of the drug, and the needle allows you to make thin and point injections. The cannula has a thick tip that does not allow for puncture close to the surface of the skin.

According to cosmetologists, the correction of the shape of the lips is preferably done using a regular needle. In cases where the patient needs to fill in small scars or eliminate wrinkles, the use of a needle is also implied.

Cannulas, in comparison with needles, have a high cost, which leads to an increase in the price of the procedure.

Not every beautician is qualified to use cannulas. In addition, some patients may have contraindications to the use of cannulas.
