Hormone injections for scars, clinically, refers to the treatment of hyperplastic scarring, using glucocorticoid injections locally to soften the scar and improve its appearance. Hormone injection within the scar belongs to the local application of hormones, standardized operation generally does not have side effects. After local injection of glucocorticoid, the drug will inhibit the proliferation of fibroblasts, which will gradually soften the local hyperplastic scar tissue, thus improving the appearance of the scar, which is one of the commonly used treatments for scarring. Standardized local application of hormones generally does not cause damage to other organs of the body. Local application of glucocorticosteroids may also cause side effects such as localized indentation and pigmentation abnormalities. For some allergic patients, local injection of glucocorticosteroids may also stimulate the body’s immune system, resulting in increased permeability of local blood vessels, which may lead to itching, rash, anaphylaxis and other symptoms. It is recommended that patients who are willing to be treated go to a regular hospital and ask the specialist to standardize the operation to avoid adverse consequences.
