The principle of Mesotherapy is the introduction of medicinal solutions into the upper and middle layers of the epidermis. For subcutaneous and intradermal injections, special syringes are used, the choice of which depends on the composition of the anti-aging solution and the area of drug administration. Needles for beauty injections are selected by specialists to make the procedure less painful and traumatic.
Depending on the area of treatment, a certain type and size of cosmetic instrument is used. Needles of various diameters facilitate better penetration of the drug under the skin and into tissue cells, making the procedure free of complications and easier to tolerate by patients.
What is an injection needle for needle mesotherapy - characteristics
A medical injection needle is a thin, hollow stainless steel rod. On one side the tube has an oblique and sharp cut, on the other side there is a short coupling for connection to the tip of the syringe.
The medical instrument for injection consists of:
- Tubes The main part is a metal rod. A medicinal solution is drawn inside it.
- Grounds. Typically made from colored polypropylene. The diameter is determined by the color of the plastic part.
- Connecting part. This is where the junction between the base and the steel tube is located. For fastening strength, special glue is used.
Dimensions
For mesotherapy, consumables with a certain type of tip sharpening, called a “Labelle needle,” are used. The cut is sharpened by laser grinding, which reduces the risk of damage to blood vessels and bleeding.
The size of the instrument is calibrated according to the Gage scale and marked with the Latin letter G. Table of sizes and diameters of mesotherapy needles:
| Calibration code | 27 | 28 | 29 | 30 | 31 | 32 | 33 |
| External diameter mm | 0,40 | 0,36 | 0,33 | 0,30 | 0,25 | 0,23 | 0,20 |
| Application area | for scalp, hair and body | for all zones | for all zones | mesotherapy of head and face | for all zones | conventional and fractional mesotherapy | microinjections |
How to find out your needle size
The size of the source is indicated on the packaging, but it can also be determined by the color of the plastic cap. Color codes for disposable injection needles used in mesotherapy and microinjections are regulated by a special standard:
- 27 G – gray;
- 28 G – blue;
- 29 G – red;
- 30 G – yellow.
When choosing a source, you should pay attention to the internal diameter or wall thickness, as well as the length of the piercing part.
The color of the cap 31G, 32G and 33G is not regulated by the standard.
The sizes and color codes of meso-needles comply with the national standard for medical equipment GOST R ISO 9626-2013.
How to choose the diameter
The internal diameter of the meso-needle depends on the cosmetic solution. Viscous formulations for thick fillers are injected using larger instruments. Thin analogues can be used for injections with vitamin and mineral cocktails.
Before the procedure, many drugs are drawn into a syringe using a regular medical needle. For mesotherapy, change to a suitable size.
Microinjections are made with needles whose inner wall thickness is 0.25-0.22 mm. Sometimes thinner consumables are used for the procedure - nanoneedles or Sit, the diameter of which is 0.16 mm.
Wall thickness
For anti-aging procedures, needles of standard diameter are often used. The thickness of the inner wall of the instrument used to administer vitamin compounds is 0.22 mm. Thin allows liquid solutions to pass through well and eliminates the risk of developing hematomas or severe swelling.
Ultra-thin with a large internal diameter are able to pass viscous compounds and gels. This allows you to use thick mixtures and cosmetic solutions without increasing the size of the consumable. The very thin inner walls have nanoneedles that are capable of delivering highly viscous drugs. Piercing the skin with such an instrument does not cause pain or other negative reactions.
How long are the needles for a facial rejuvenation procedure?
The length of the piercing part of the meso-needles depends on the depth of drug administration. The cocktail is injected into the lips and to tighten the skin around the eyes to a depth of no more than 2-4 mm, so the length is 3-6 mm. The short dispenser ensures precision injection in small dosages.
To carry out rejuvenating procedures in other areas, medical instruments of greater length are used - up to 25 mm. Injections with adjustable length are used to correct several areas. Carrying out procedures simultaneously allows you to use one consumable.
Home alternative
The meaning of mesotherapy is to rejuvenate the skin by regenerating the epidermis using cosmetics. Some devices for home use have similar capabilities:
- Mesoscooter.
- Gezatone massager.
Both of these mesotherapy devices do not violate the integrity of the skin during use.
You can find out how to carry out mesotherapy at home and what techniques are used during the procedure here.
Mesoscooter
The mesoscooter looks like an ordinary roller covered with sebaceous needles of various lengths.
For home use, it is recommended to purchase a mesoscooter with needles 0.5 mm long.
It is better to use a mesoscooter in the evening. Before the procedure, you must thoroughly wash your hands and the area of skin that will be treated. Treat everything with chlorhexidine.
Reference! The mesoscooter is more effective in combination with cosmetic substances: creams, masks, serums.
- A nutrient (for example: anti-wrinkle cream) is applied to the skin.
- After which rolling is done 5-10 times.
- The area is then treated again with chlorhexidine. Treatment with the solution is performed once a day for the next 3 days.
- Night cream is applied to the epidermis.
As for more active substances, the mesoscooter can be used with cosmetic preparations :
- elimination of wrinkles and moisturizing of the skin - hyaluronic acid concentrate;
- whitening, getting rid of age spots – ascorbic acid;
- tightening sagging skin - elastin or collagen concentrates.
Regular use of the device will improve skin tone , even out complexion, reduce the rate of hair loss and even accelerate hair growth, smooth out wrinkles, scars.
The price of a mesoscooter for home depends on the material from which it is made. In Moscow and St. Petersburg it ranges from 750 rubles to 2500.
More information about using the mesoscooter is described in this video:
Cosmetic needles for mesotherapy - classification and types
The effectiveness of the procedure depends on the correct choice of tools. The technique of skin rejuvenation and correction of defects involves injections of biologically active solutions into the deep layers of the dermis.
There are several types of needles that can be used for mesotherapy. Mesoneedles differ in the sizes of internal and external diameters, length and cut angles. The types of consumables are selected depending on the type of procedure and the drug administered. This is the only way to ensure a painless injection in the face for rejuvenation and reduce the risk of side effects.
Nanoneedles
Atraumatic stainless steel with ultra-thin walls are widely used for anti-aging procedures. Nanoneedles provide painless administration of mesotherapy agents and minimize the risk of injury to the skin and blood vessels.
Due to the wide internal diameter, atraumatic ones can be used for solutions with a high degree of viscosity. This type is the thinnest - their internal diameter does not exceed 0.16 mm.
Advantages:
- special sharpening;
- no traces after the injection;
- minimal risk of blood loss and injury to nerve endings.
SIT needles
SIT or SIT is the designation of the shortest needle for cosmetic and medicinal injections. A special feature of this type of consumable is its design. The meso-needle is up to 2 mm long and is located inside a special plastic cap with a vacuum suction cup. This design allows the injection depth to be limited.
Thanks to this design, the solution does not penetrate the skin deeper than 1-2 mm, which ensures minimal risk of injury to the surface of the epidermis. The vacuum effect facilitates the administration of the therapeutic cocktail and makes the procedure completely painless.
Due to the presence of a cap, the length of which is equal to the size of the consumable, SIT needles are not used to smooth out micro-wrinkles and small scars.
What is the difference between mesotherapy and conventional
“Labelle needles”, which are used for mesotherapy, have a number of differences from conventional medical instruments. A special feature of meso-needles is the cut length, which is approximately 30º. The material for microinjections is much shorter - the length of mesotherapy is 2 (for SIT), 4, 6, 9, 13 and 24 mm.
The differences also apply to the syringe with which the injection is given. For the skin rejuvenation procedure, three-component instruments with a rubber sealing ring on the piston are used.
Features of the papular technique
This method of mesotherapy allows the injected drugs to be better deposited due to the creation of papules of different diameters. A papule is a hemispherical formation that occurs due to infiltrate entering the dermis and lifting the epidermis. They differ in diameter, as well as the depth to which the substance is introduced. The advantage of this technique is that it helps to prolong the effect. This occurs due to the fact that the mesopreparation lingers in the papules for several days. Depending on the depth of injection, superficial and medium papules are distinguished.
Micropapules (superficial)
Mesococktail introduction zone. This technique can be used to deliver drugs to areas with a low subcutaneous fat content - forehead, cheekbones, décolleté, neck, corners of the lower jaw, hands.
Features of execution:
- The insertion depth is 1-2 mm.
- The diameter of the papules is 1.5-2 mm.
- The angle of the needle is 10-15° (it is necessary to hold the syringe so that the bevel of the needle is on top).
Using this technique, you can introduce any meso-cocktails.
Medium papules
Mesococktail introduction zone. Used to treat blood vessels, as well as for injections into the scalp.
Features of execution:
- The insertion depth is 2-3 mm.
- The diameter of the papules is 2-4 mm.
- The needle angle is 45°.
Since the papule in this case has a larger diameter, the filler stays in it longer, and accordingly the therapeutic effect will be stronger. The technique is applicable in areas such as the head, body, and face. After the session, there may be redness, slight swelling, and bruising.
Which technique should be chosen when administering mesopreparations?
Before administering medications, be sure to read the instructions for the drug and the methods of its administration. There are preparations on the market with stabilized hyaluronic acid (skin boosters), which are administered to avoid the formation of papules. If these drugs are administered using the technique described, the papules may remain for many months. Instead of improving appearance, the patient will receive the opposite effect.

Why? Are there any disadvantages?
Time
. The most golden resource. From forty to fifty minutes - this is how much is spent on applying and removing the external anesthetic.
No choice
. Currently, one type of local anesthetic is registered and widely used.
Inability to combine procedures
. In effective protocols for treatment and aesthetic correction of the skin, it is important to combine several procedures in one step. For example, when stimulating collagen, excellent results are obtained using hardware and injection techniques. The most common: hybrid peelings and biorevitalization; fractional laser rejuvenation and plasma therapy; radio wave lifting and introduction of a placental drug to acupuncture points. Although some protocols provide for the application of anesthesia, we take into account that the combination of techniques that damage the skin and the application of an anesthetic may result in undesirable effects.
Inability to apply local anesthetic to large areas of the body
. For example, with body mesotherapy it takes a lot of time and there is a risk of systemic exposure.

Risk of contact dermatitis
.
It has always been and is, but now, with the widespread wearing of protective masks, it has increased. Even those patients who had never experienced dermatitis began to complain of this condition (Fig. 1)
. At first, the patient does not feel anything, then complaints of tingling and burning appear; after cleansing the skin, hyperemia, peeling and (subjectively) itching of the skin may be observed.
Treatment takes from 3 to 7 days, which is very frustrating for doctors and patients and reduces patient loyalty and trust in the doctor.
Standard treatment plan for contact dermatitis:
- Cleansing the skin twice a day with a mild dermatological gel
- Applications of a mixture of cream with panthenol + hormonal ointment
- Avoiding the sun, baths, saunas and applying cosmetics
conclusions
- The effectiveness and painlessness of mesotherapy depends on the correct choice of injection needle. To carry out the rejuvenating procedure, consumables with a puncture thickness of no more than 0.4 mm are used.
- The medical instrument is selected taking into account the composition and consistency of the injected solution. The larger the internal lumen of the tube, the better its conductivity.
- The result of the procedure is influenced by the type of grinding and the quality of the materials used. The best manufacturers of medical equipment for cosmetic procedures are large European companies.
- The type and size can be determined by the color code and information on the packaging. We also recommend that you familiarize yourself with the types of Botox for the face in this material.
Local anesthetic. Composition and effect on the skin
This is a combined anesthetic for external and local use. Contains lidocaine and prilocaine, amide-type anesthetics. Skin anesthesia is caused by the penetration of lidocaine and prilocaine into the layers of the epidermis and dermis.
In adults, after applying a drug containing this combination in a single dose for 3 hours, the systemic absorption of lidocaine was approximately 3%, prilocaine - 5%.
Absorption is slow. Cmax of lidocaine (average value 0.12 μg/ml) and prilocaine (average value 0.07 μg/ml) in blood plasma was achieved approximately 4 hours after application. The risk of toxic symptoms exists only when the concentration of active substances in the blood plasma is 5–10 mcg/ml.
Local reactions:
in the area of application, transient local reactions are possible, such as pallor, redness and swelling; at the first moment after application there is a slight burning sensation, itching and a feeling of warmth. Hemorrhagic rash or pinpoint hemorrhages, especially after prolonged application in children with atopic dermatitis or molluscum contagiosum. Irritation of the cornea upon contact with the mucous membrane of the eye.
General reactions:
allergic reactions, in the most severe cases - anaphylactic shock. Methemoglobinemia and/or cyanosis.
When counseling patients, the pain from the procedure is often described by doctors as tolerable. Practitioners often reduce the manifestations of sensitivity in patients and promise minimal pain, but in practice the promises do not always come true.
Patients who have experienced pain may experience anxiety, which reduces loyalty to the procedure and subjectively reduces the achieved result. And, of course, when assessing the final result and deciding on a long course of procedures (this applies to a greater extent to trichological treatment), comfort during the injection plays a decisive role.
How are they different from regular ones?
The device consists of a steel tube - the needle itself, which penetrates the cover, a plastic part and a connecting section, which attaches the metal tip to the base.
There is only one difference between conventional therapeutic devices and those used in cosmetology: the tip of piercing instruments for cosmetologists is cut at an angle of 30 degrees, which ensures precise hitting of the desired area without injuring nearby tissues.
We recommend reading about Sakura mesotherapy products. From the article you will learn about the composition and features of Sakura preparations from Japan, indications for mesotherapy, the technique of performing the procedure with Sakura, and the results. And here is more information about biorevitalization with the drug Ivor Hydro.
How deep do biorevitalization needles go?
The depth to which the needle goes during biorevitalization depends on the chosen technique: microinjection - 0.1 cm, linear - 0.4 cm.
Microinjections
Microinjections are usually carried out in 3 ways:
- "Picotage" . It is used when it is necessary to activate the work of hyaluronic acid in the Grenz zone, formed by newly formed collagen fibers.
- "Point by point" . Used to reduce the severity of facial wrinkles, it is performed strictly along a certain trajectory directly near the skin crease.
- "Papular" . It is carried out only when the administered drug has a healing effect. Can be used on the face, décolleté, neck and hands.
Papular technique
Each of the varieties involves inserting a needle 0.1 cm.
Linear
The linear technique is divided into 2 types:
- "Fan" . All injections are carried out from one point, and the direction is changed by turning the sharp end. Used to enlarge lips, tighten corners and in the area of nasolabial folds.
- "Net" . It involves introducing the product in lines perpendicular to each other at the same depth. Needed to increase volume in the area of the cheekbones, cheeks and to reinforce tissues that have lost elasticity.
These methods are also carried out at the same level - 0.4 cm.
