The cannula, according to doctors, is a significant discovery of the 21st century in cosmetology and contouring. Recently, rejuvenation with the help of injections 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 conventional needles, they have a blunt end, which avoids soft tissue damage and reduces patient pain. Due to its flexibility, the cannula expands and bends the vessels without injuring them.
The idea of bendable blunt needles was proposed by a plastic surgeon from France, Bernard Herzog in 2009. The first cannulas were used in plastic surgery to remove adipose tissue. Later, their advantage was also appreciated in cosmetology.
Cannula - application in cosmetology and contour plastics
Cannulas have been used in cosmetology and contour plastics relatively recently. Cosmetologists note that when using the cannula, the contours of the face 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, so it is carried out with a needle.It is also used in cases where it is necessary to inject with a stroke or close to the skin.
In cosmetology, using cannulas, the oval of the face is leveled, age-related changes are eliminated, injections are made to moisturize the skin. In contour plastics, cannulas are used in procedures to eliminate laxity of the skin of the face, neck and décolleté; enlargement and correction of individual areas; smoothing deep wrinkles.
Cannula advantage - which is better: needles or cannulas
The main advantage of the cannula is its flexibility. Thanks 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, since aesthetics play an important role in cosmetology. Unlike traditional needles, cannulas allow the most accurate distribution of the substance under the skin. This gives beauticians the opportunity to achieve the most natural contours.
According to doctors, cannula injections are considered the safest. It is perfect for treatments in hard-to-reach and sensitive areas such as the neck, browbone, temples, cheekbones, bridge of the nose and around the eyes.
Rejuvenation with a cannula is carried out through a minimal number of punctures, which makes the procedure almost painless and shortens the healing time.
If we compare cannulas with needles, then the first has a lot of advantages. But there are certain injections that cosmetologists prefer to do 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%. The recovery time is reduced to several days.
disadvantages
Despite the weighty list of advantages, the cannula is not without its disadvantages. Among them:
- High qualification requirements for a specialist. The injection procedure using a cannula is much more complicated than a needle, so the 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.
- Large consumption of material. On average, the amount of spent substance increases by 15%. This is a significant disadvantage, given the high price of cosmetics.
- Increase in the cost of the procedure. In most cases, drugs are dispensed ready-made. The set comes with a regular needle. Cosmetic centers have to buy additional cannulas separately, and this leads to an increase in the cost of injections. Many patients do not agree to the additional costs.
- Contraindications. Cannulas are not prescribed in cases where the client is repeating the procedure 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 microscars are formed during healing, through which it will be difficult for the cannula to pass.
Contraindications
It is undesirable to carry out injections on inflamed skin areas. The use of cannulas is also not recommended for patients with skin problems or with skin prone to scarring. It is contraindicated to carry out the procedure in areas after injections with collagen and hyaluronic acid.
