Softening injections are usually absorbed by the body immediately after injection and continue to work. Softening injection is one of the methods used to treat scars, usually glucocorticoids, mainly through the hormone to reduce the high immune response state of the local scar tissue, inhibit the proliferation of fibroblasts and the ability to synthesize collagen and other extracellular matrix, and accelerate the breakdown of collagen. The softening injection will be absorbed by the body immediately and continue to work. According to the scar proliferation and individual physique, the injection will be given once every 2-4 weeks, and 5 times will be a course of treatment. If the scar is small, it is only necessary to inject into the scar locally, which is usually only absorbed locally, with less side effects and relatively safe; if the scar is large in size, it is not recommended. If there are side effects such as obesity, menstrual irregularities, etc., the drug needs to be stopped or reduced, and must go to a regular hospital for consultation and treatment.
