In general, it is relatively safe to choose a regular medical cosmetology organization for Botox, but some patients may experience allergic reactions, and complications such as stiffness of facial expression may also occur if the medical staff operates improperly or the patient is not properly cared for after the procedure. Botox, also known as botulinum toxin and botulinum toxin, is a bacterial exotoxin produced by the bacterium Clostridium botulinum in the process of reproduction. Botox can block the nerve impulses between the nerve and the muscle, so that the over-contracted small muscle relaxes, thus achieving the effect of wrinkles. However, botulinum toxin is a biological protein, and some patients may have allergic reactions or even anaphylactic shock after injection. Therefore, those who are allergic or hypersensitive to any of the ingredients in Botox products need to be prohibited from injecting Botox. In addition, complications such as drooping eyebrows, upper eyelid weakness, pain, and stiffness of facial expression may occur if the medical personnel do not operate properly or if the injection position is not appropriate. It is recommended to choose professional cosmetic medical institutions for injection and follow the doctor’s instructions for daily care, such as avoiding local massage and strenuous exercise after surgery, and abstaining from spicy, seafood and other stimulating foods in terms of diet. It is recommended that patients go to regular professional medical plastic surgery institutions to reduce the occurrence of complications.
