If you want to get disfigured, a shot of growth factor is enough
Distinguish beauty
At present, external growth factors are safe and effective, and have the effect of promoting wound healing.
However, it needs to be emphasized that growth factors can only be used externally. Injection or oral administration is illegal and is explicitly prohibited by the state.

Nowadays, on some social media, many Internet celebrity bloggers will recommend a filling injection material called "growth factor", saying that as long as it is injected into the recessed part of the face, it can promote the growth of cells in that part and make it It becomes a "self-filling", filling up the originally "collapsed" part.
In this regard, Li Gang, the chief physician of the Plastic Surgery and Medical Aesthetic Department of the Second Hospital of Tianjin Medical University, said that the current external growth factors are safe and effective and have the effect of promoting wound healing.
"However, it needs to be emphasized that growth factors can only be used externally. Injection or oral administration is illegal and is banned by the state." Li Gang said.
Use method is limited to external use
Previously, there have been many reports that some people who love beauty have been injected with growth factors, causing their chins to grow wildly and their foreheads to bulge. This has caused people to talk about the discoloration of growth factors.
"Growth factor is a kind of cytokine. It is a kind of peptide substance that regulates cell growth by binding to specific, high-affinity cell membrane receptors." Li Gang explained that growth factors will pass through the specificity of the plasma membrane. Receptors transmit signals to cells and act on genes related to cell proliferation to affect cell growth or differentiation.
In short, growth factors are substances that can promote cell growth and proliferation.
The human body secretes a variety of growth factors, which regulate and control the growth, development, metabolism, aging and other life activities of the body's cells.
"From a physiological point of view, there are three types of growth factors, of which there are two types of growth factors that have cosmetic effects." Li Gang introduced that the first type is epidermal growth factor, which can promote epidermal growth and stimulate The division of basal cells to repair damaged epidermis; the second is fibroblast growth factor, which can promote the growth of collagen and help the recovery of the dermis.
These two kinds have cosmetic effects.
The third type is vascular endothelial cell growth factor, which can promote the growth of blood vessels and lymphatic vessels.
Clinically, growth factor is a regular topical drug. After skin injury, whether it is an acute or chronic wound, the growth factor can accelerate the healing of skin wounds.
"Skin aging is actually a chronic injury of the skin, which is also the principle that growth factors can be used for beauty. At present, epidermal growth factor and fibroblast growth factor are also widely used in medical skin care." Li Gang said, growth factor It can repair damaged skin (cornea and epidermal damage) and skin after laser surgery.
It can regenerate the epidermis and help the skin form a healthy barrier.
This barrier is very strong, which can improve the skin's heat preservation, anti-allergic and anti-radiation capabilities.
However, Li Gang emphasized that the use of growth factors is limited to external use, regardless of whether it is used as a medicine or a beauty product. The general method of use is smearing or spraying.
Cells may grow disorderly after injection
"External growth factors are safe and effective and can be used as therapeutic drugs, but the state only approved their use as external drugs. If injection or oral administration is illegal, it is impossible for growth factor injections to appear in regular hospitals." Li Gang said.
Data show that many patients who are disfigured by the use of growth factors are injected with growth factors or drugs containing growth factors.
Some people cause facial abnormal growth after injection of growth factors, such as irregular swelling of the skin.
"After the growth factor is injected into the human body, the growth-promoting effect it exerts is uncontrollable and will lead to a disorderly and disorderly growth, which may have a series of adverse effects." Li Gang said.
First of all, after the growth factor is injected into the human body, it will stimulate the rapid proliferation and proliferation of skin cells around the injection site, leading to infinite or abnormal growth of tissues, redness and hardening of the skin, and the newly grown tissues often exceed the expected size , And eventually may even lead to disfigurement.
Secondly, once a problem occurs, it is very difficult to remove the growth factors.
Even if the doctor performs the removal operation, it is difficult to guarantee that there is absolutely no residue.
"Even if the growth factor is only a little bit left in a certain part, the part can grow wildly." Li Gang said.
In addition, the injected person may also be disfigured due to the human factor of the injection.
For example, due to improper injection technique or operation, growth factors are injected into large blood vessels and cause vascular embolism; pinhole infections cause skin purulent, scars and even keloids.
"In short, my country has not approved any growth factor filler drugs, and drugs containing growth factors are prohibited from being used for tissue augmentation." Li Gang emphasized.
Growth factors often change for "vest" to appear
Despite the state's explicit prohibition, accidents involving disfigurement due to injection of growth factors still often appear in the news.
"The plastic and beauty industry will pop up a so-called'high-tech product' every once in a while. These new products are probably just replacing the'vest' with the illegal injection filler.'Freeze-dried powder, growth peptide, and stem cell' Qingchunsu'... these products that sound like'tall' are actually growth factors." Li Gang reminded that many beauty seekers were injected with these growth factors in "new clothes" without their knowledge. Once the injection area is found to be abnormally uplifted and continues to grow, it is recommended to go to a regular hospital for examination as soon as possible.
So, if there is a filling demand, which products can the majority of beauty lovers choose?
"The most commonly used injection filling is hyaluronic acid (Hyaluronic acid). The human skin itself contains a large amount of hyaluronic acid. It is the skin's moisturizing factor. After being injected into the human body, it can expand to 500 to 1000 times the original value. In addition to moisturizing In addition to the characteristics of volume expansion, it also has biological stability, is not easy to transfer and does not hold water, which also makes the filling efficiency and safety of hyaluronic acid extremely high, and it is a good tissue filler." Li Gang pointed out, like water The light needle also contains hyaluronic acid.
Because injection cosmetology belongs to micro plastic surgery, many people who love beauty think that it has small side effects and quick recovery, so this type of project is very popular.
In this regard, Li Gang reminded that even minor plastic surgery does not mean "no risk, slight risk."
"The'micro' of micro plastic surgery does have the meaning of minor damage, but it does not mean simple and easy, but more refers to the subtle and subtle technology. When performing these medical beauty projects, beauty lovers need to keep their eyes open. Find a regular medical institution and qualified professional doctors for micro plastic surgery, instead of turning micro plastic surgery into a'dangerous plastic surgery'." He said.
Relevant experts said that when injecting hyaluronic acid, it is not uncommon for the injection staff to have no professional and formal medical education, coupled with the lack of understanding of facial anatomy, causing vascular embolism and nerve damage in patients, and serious cases can also lead to Skin necrosis can even cause blindness, hemiplegia, and death.
"In recent years, the'face value economy' and'pleasure consumption' have grown vigorously, and the medical aesthetics industry has sprung up. The strong demand has not only promoted the development of the market, but has also given birth to a lot of chaos in the industry. People who love beauty should not blindly follow the trend, and don't just try any product "fire". They should learn more about medical beauty and choose regular hospitals or beauty institutions for medical beauty operations." Li Gang emphasized again.
