Because of its cheap price and wide source, growth factor is often used as hyaluronic acid by some illegal organizations or private studios, or packaged as “growth peptide”, “lyophilized powder”, “stem cell It is often used as hyaluronic acid by some illegal organizations or private studios, or packaged as “growth peptide”, “lyophilized powder”, “stem cell” and “baby shot”, “beauty shot” and other so-called high-tech products to obtain high illegal benefits. For the drug growth factor, it has a very good effect in trauma treatment, but it is a topical application type of drug and cannot be injected. To use an inappropriate analogy, hemorrhoid cream is effective but not eaten, and platelet is good but not injected, the two do not conflict. For the growth factor injection, it is true that a small number of people do not have problems after the injection. However, most of the candidates will have hard lumps, nodules or even crazy growth of tissues and sarcoma-like deformities after the injection. The growth factors currently used in injections are usually mixed types of growth factors produced in China, which are very diverse and disorganized, and may contain dozens of growth factors in them. After it is injected, it will lead to uncontrolled and crazy tissue growth. After the exogenous growth factor is injected into the body, its development does not follow the body’s regulation, and there is a tendency of unlimited growth, which is similar to benign tumors, and is commonly found in the injection of chin, nose bridge, nasolabial folds, apple muscle and other locations. For the removal of growth factors, it can be very troublesome. This is because if all of the tissue is removed, it will inevitably affect the aesthetics of the appearance. However, if some of the tissue is left in place, it may lead to unlimited growth. In one of my cases of growth factor removal, I left two green bean-sized growth factors in order to maintain the aesthetics of the chin, but only three months after the surgery, the patient came back to me and found that the growth was as big as before in just three months. The above case is a chin augmentation, if it is an injectable filling of the tear trough and apple muscle, because there are more nerves and blood vessels, I dare not remove them completely, so it will be more troublesome to deal with them, and the final result may be that they will never be clean. Therefore, for the “latest technology” from unknown sources, or very low cost hyaluronic acid, you must be vigilant.
