Hi Egypt. We do not know of a cream that could be used for a hematoma. In addition, if a bruise were related to a Botox injection, we would normally use a pulsed dye laser to break up the bruise. This usually takes about 48 hours for the bruise to go away after treatment.
It is possible to get a bruise from injections, any injections on the face but very rare to get a hematoma, which is a colleciton of blood enough to feel a lump, underneath the skin. If there is a bruise that forms, which is very rare from Botox injections in my practrice, but does happen, I have recommended an Auriderm vitamin K cream which may help the processing of the iron in the blood cells to diminish the bruise faster. Arnica montana, an herb, taken internally, as well as Bromelain, may reduce the bruising faster. Speak with your doctor about this.
