Full face lipofillers may have bad effects such as localized infection, hematoma, itching, and unevenness. Full face liposuction is generally used to inject autologous fat into the face as a filler, which is suitable for cases with little fat in the face, too thin, or asymmetry and concavity in the face. There may be bad effects of full face lipofilling. Filling is an invasive operation, and there may be the possibility of infection during the operation and after the operation if the care is not proper. Secondly, if improper operation injures blood vessels, local hematoma may occur. Localized itching may also occur after the operation, and patients should avoid scratching the affected area. In addition, autologous fat can generally be absorbed, if the local absorption is not balanced, uneven filling, perhaps leading to facial unevenness. For those who need full face lipofilling, it is recommended to consult a doctor in a regular hospital to understand the relevant matters.
