How to Choose the Needle Size for Mesotherapy?

Mesotherapy is a minimally invasive skin resurfacing technique. Compared with traditional plastic surgery, more people tend to accept and enjoy this treatment. This treatment uses tiny needles to pierce the skin and inject active ingredients to improve the skin condition. It is an efficient beauty treatment with multiple effects.

In mesotherapy, the choice of needle is crucial. Different needle sizes will affect the absorption effect of the drug, the comfort of the treatment, and the final treatment effect. Generally, the size of the mesotherapy needle can be determined according to the viscosity of the injection solution, the treatment area, and the purpose of the treatment.

Read the following content to learn more about the needle size selection for mesotherapy.

Basic Parameters of Mesotherapy Needles

This therapy uses a small needle to inject nutrients, vitamins, antioxidants, growth factors or fat-dissolving ingredients directly into the mesoderm of the skin, which has a variety of effects, including improving skin quality, promoting collagen production, reducing fat accumulation or promoting hair growth.

Compared with oral or intravenous infusion, mesotherapy can precisely act on the target area, the drug is absorbed faster, and the effect is more significant.

When choosing a mesotherapy needle, two parameters are mainly considered, which directly determine the drug penetration effect and the patient's experience.

l Needle length: The longer the needle is, the deeper it will penetrate into the skin tissue, usually between 4mm and 13mm. Shorter needles (4mm-6mm) are suitable for surface injections, such as skin booster injection, while longer needles (8mm-13mm) are suitable for deep tissues, such as fat dissolution and collagen regeneration.

l Needle diameter (Needle Gauge, G): Indicated by "G", the larger the value, the thinner the needle. For example, 30G (diameter about 0.3mm) is thinner and less painful than 27G (diameter about 0.4mm). Thin needles help reduce treatment pain and tissue damage, while thicker needles are suitable for injections of high-viscosity drugs, because the higher the viscosity, the larger the injection space required.

Needle Selection for Different Treatment Goals

1. Skin whitening and skin booster injection

Recommended needle size: 30G-34G, length 4mm-6mm

Scope of application: The introduction of active substances such as hyaluronic acid, vitamin C, amino acids, etc. These skin boosters can revitalize the skin, brighten the dull skin, but only this, and have no wrinkle removal effect.

Features: Small and short needles reduce pain and avoid skin damage. They are suitable for injection into the epidermis and superficial dermis. Skin boosters for whitening and moisturizing do not require needles that are too long or too large in diameter.

This type of treatment usually requires multiple point injections, using a micro-push injection method to achieve the effect of evenly distributing the drug. The thinner the needle, the less pain the patient feels, and the redness and swelling reaction after treatment is relatively mild.

2. Firming, anti-aging and collagen regeneration

Recommended needle size: 29G-31G, length 6mm-13mm

Scope of application: peptides, PRP (platelet-rich plasma), collagen stimulators, these injection solutions can promote skin firming, stimulate the production of more collagen, thereby reducing fine lines on the skin, promoting skin firming, and restoring the youth of the skin.

Features: The longer needle can penetrate deep into the dermis, promote collagen production, and maintain comfort.

Anti-aging treatments usually require drugs to act on the dermis to stimulate fibroblasts to synthesize collagen, thereby improving skin sagging and wrinkles.

The concentration of collagen is greater than that of whitening and hydrating nutrients, so a larger diameter needle is required.

3. Lipolysis and shaping

Recommended needle size: 25G-30G, length 8mm-13mm

Scope of application: lipolysis drugs (such as deoxycholic acid), firming lipolysis injections. For lipolysis injection, it can help plasticity, reduce the volume of fat, and effectively achieve the purpose of weight loss.

Features: The thicker needle is convenient for pushing viscous liquid, but the pain is relatively high, which is suitable for local fat reduction.

Lipolysis treatment usually targets local fat accumulation areas such as the mandibular margin, double chin, arms and abdomen, so a longer and thicker needle is required to inject the drug directly into the fat layer.

4. Scalp mesotherapy (hair regeneration treatment)

Recommended needle size: 30G-32G, length 4mm-6mm

Scope of application: hair growth liquid, PRP, vitamin B, etc. It is used for injection of scalp nutrient solution to stimulate the activity of hair follicles, prevent hair loss, and make hair more luxuriant.

Features: The fine needle reduces scalp damage and improves the absorption of effective ingredients. The goal of scalp mesotherapy is to stimulate hair follicles and promote hair growth, so the drug needs to penetrate into the dermis accurately, and avoid too deep injection to cause pain and side effects.

Using a fine needle can reduce the patient's discomfort, while improving the uniformity of drug distribution around the hair follicles and improving the treatment effect.

5. Ultra-fine treatment: application of 34G needle

Recommended needle size: 34G, length 4mm-6mm

Scope of application: It is used for fine injection around the eyes and lips, epidermal nutrition introduction, scalp mesotherapy. More precise injection, less pain, no greater feeling.

Features: The 34G needle is extremely fine (about 0.18mm in diameter), suitable for treatments that require extremely low pain and extremely shallow injections.

The skin around the eyes and lips is thinner and more sensitive to pain, so using a 34G needle can reduce congestion and swelling and improve patient comfort.

In addition, it is also suitable for scalp mesotherapy, because the thinner needle can reduce the pain during injection, while ensuring uniform penetration of active ingredients and improving the treatment effect.

Factors Affecting Needle Selection

1. Treatment area

Face, eye area and scalp: It is recommended to use 30G-34G, 4mm-6mm needles to reduce pain and damage. Since the facial skin is thin, especially the area around the eyes, fine needles help improve the safety and accuracy of treatment.

Body: 25G-30G, 6mm-13mm, deep injection is better. For example, body fat dissolution requires thicker and longer needles to ensure that the drug can effectively reach the fat layer.

2. Viscosity of the injection product

• Low viscosity (such as vitamin C, amino acids): 30G-34G fine needles can be used to improve comfort, allow active ingredients to penetrate evenly, and increase absorption rate. Diaminy offers high quality skin booster, providing rich hydration for the skin. 
• Medium viscosity (such as PRP, collagen regeneration agent): 28G-30G is recommended to ensure that the drug can be smoothly advanced and reduce pain, while avoiding clogging of the needle and improving the fluency of treatment. Diaminy offers premium collagen regeneration skin booster, which are called exosome. It is often used for anti aging treatment. 
• High viscosity (such as cross-linked hyaluronic acid, lipolysis needle): It is recommended to use 25G-30G. The thicker needle is easy to push and prevent needle blockage, and can effectively reduce the resistance during injection, so that the drug can enter the target tissue more smoothly.

Precautions for the use of mesotherapy needles

• Strict aseptic operation: Use disposable sterile needles to avoid cross-infection to reduce the risk of infection.
• Reasonable control of injection depth: Too shallow may lead to poor effect, too deep may increase congestion or pain, and the injection method should be adjusted according to the characteristics of the site.
• Injection speed and pressure control: Slow injection can reduce pain and fluid extravasation, improve absorption rate, and reduce tissue risk.
• Postoperative care: Avoid irritating skin care products, sunscreen and infection prevention to promote recovery and reduce adverse reactions such as pigmentation.

Summary

The choice of mesotherapy needles directly affects the treatment effect and patient experience. Reasonable needle selection can not only improve the comfort of treatment, but also enhance the absorption effect of drugs, so that patients can get more ideal therapeutic effects.
