The advertisements put out by many beauty agencies are

"1 needle = 8000 masks"

(or 5000? 3,000? It's really attractive. )

So, Bian Xiao will explain it to you today.

What is a "water needle"?

Is it "water muscle" after the fight?

What is a "water needle"?

The word "water needle" sounds tempting. It seems that a needle can make your skin "watery" and "shiny". However, it is actually the name of a cosmetic injection technology. According to the needs of beauty seekers, it injects one or more cosmetic materials into the skin with a special injection instrument (not a common syringe) to achieve hydration.

Simply put, it is to directly inject the beauty ingredients that are coated on the skin surface but cannot be absorbed into the dermis of the skin.

As for the price you care about, it is generally between 1000 yuan and 10000 yuan, which is very different.

The main injection material of "Shuiguang Needle" is hyaluronic acid which we are familiar with. But other injection materials can also be mixed to achieve different skin beautifying effects.

Therefore, the "water-light needle" is not a novel plastic surgery technology, but is essentially based on the beauty of hyaluronic acid.

So take a 1 needle =8000 mask or something and have a look.

What is hyaluronic acid?

Hyaluronic acid is a kind of macromolecular mucopolysaccharide, which widely exists in human tissues and has many physiological functions, such as lubricating joints, regulating vascular wall permeability, and regulating protein.

This substance is so popular in the field of medical beauty, mainly because hyaluronic acid is one of the main matrix components of human skin, and its function is to keep skin cells moist, protect cells from germs, accelerate the recovery of skin tissue and promote wound healing.

If hyaluronic acid is supplemented to the skin by certain means, it can improve the nutritional metabolism of the skin and make the skin soft, smooth and elastic. So at present, there are many cosmetics and medical beauty drugs with hyaluronic acid as the main raw material, and water needle is one of them.

Of course, hyaluronic acid can also be used as non-steroidal anti-inflammatory drugs, adjuvant drugs for arthritis treatment, and adjuvant drugs for ophthalmology and cardiac surgery. Don't be too surprised if you see hyaluronic acid in the above drugs.

In addition, many people know that another name of hyaluronic acid "hyaluronic acid" is actually a wrong translation. Hyaluronic acid has nothing to do with uric acid. This word is widely used in Hong Kong and Taiwan, but it has become a household name with the spread of some beauty programs and cosmetics advertisements in Chinese mainland.

How does the water needle operate? Can I only inject hyaluronic acid?

The main medical instrument used in "water-light needle" is "water-light syringe" (or "water-light gun"), which needs to be equipped with a special disposable sterile injection needle.

"Water-light injection instrument" adopts negative pressure technology, which can inject injection materials into dermis accurately through multiple needles at the same time. Its needles are not one, but a group, usually five slender needles (some are nine). The length of the needle can be adjusted according to the skin thickness, which can not only reduce the pain during injection, but also ensure the accuracy of injection and reduce bleeding.

In other words, only Han's water injection instrument has passed the approval of China Food and Drug Administration (CFDA), and other brands of injection instruments (injection guns) are illegal, which may have potential safety hazards.

injection process

When injecting, the negative pressure system of the "syringe" will automatically suck up the skin and the needle will gently pierce. The doctor will step on the/kloc-0 pedal every time to push the syringe for injection.

The whole operation takes about 10 minutes.

Injection material

Although the "water needle" mainly injects hyaluronic acid, some beauty institutions will mix drugs such as vitamin C, glutathione, botulinum toxin and PRP (platelet-rich plasma) autologous serum stem cells for joint injection.

It should be noted that in Chinese mainland, it is not allowed to combine the above drugs for cosmetic projects at will, although it may be allowed in Hong Kong, Taiwan, Japan, South Korea and other countries.

Moreover, the more drugs are mixed, the more likely it is to produce toxic or allergic reactions. You should think twice about this risk.

injection process

Full face injection is generally 2.5~5 ml, but the doctor will increase or decrease according to different parts of each person and the drugs injected.

How long does it take to finish the "water needle" to see the effect? Will there be any side effects?

After finishing the "water-light needle", there will be a bruise period of 3 to 7 days, and the skin will improve after one week.

However, this effect is only temporary. Generally speaking, it is necessary to inject 1 time every 2~3 months to maintain the "improved state". And the actual effect varies from person to person. Because of individual differences, some people's skin really hasn't changed, so it's not as exaggerated as advertised by some beauty agencies.

Precautions for operation

1. Because "water-light needle" is an invasive cosmetic surgery and a traumatic medical behavior, the whole operation should be carried out in a sterile environment in a regular medical institution. Therefore, some beauty salons or private individuals cannot carry out it.

2. Because of the possibility of facial bleeding after operation, it is not recommended for people with coagulation dysfunction.

3. People with scar constitution or scar hyperplasia are not recommended. .

4. Follow the doctor's advice after operation, and the cleaning and nursing methods shall be carried out in strict accordance with the doctor's advice.

Side effects and complications

In view of the horror of disgusting pictures, Wei will not let go. )

1. Surface infection

It may be caused by incomplete disinfection, allergic reaction of patients or improper postoperative care.

2. Acne-like papules

Some patients will have acne-like papules on their faces after surgery, and in severe cases, acne-like pustules will appear, which are generally seen in people who have acne but are still undergoing surgery.

3. Dense syndrome

After the operation, small dense lumps appeared on the face in a large area and regularly distributed, because the operator misused inappropriate hyaluronic acid products, or the injection cortex was too shallow, or the patient was allergic.

Step 4 dye

People with sensitive constitution or recessive pigmentation may have pinhole pigmentation or aggravated original pigmentation after operation.

The actual function of "Shuiguangzhen" is to inject hyaluronic acid into the skin to replenish water and moisturize. Some beauty institutions do not have the effect of "removing spots, acne marks, wrinkles and anti-aging", and the effect can only last for two or three months. Moreover, the US Food and Drug Administration in China only approved a kind of "water needle injector" for hyaluronic acid injection, so at present, a considerable number of "water needle" injections in Chinese mainland are illegal in terms of the medical devices used.

Moreover, although there are more than a dozen legal surgical hyaluronic acid injection products in China, none of them are marked as "can be used for water-light needle injection", so whether the "water-light needle" project itself is compliant is still debatable.
