Botox injections are an effective, minimally-invasive treatment option for patients who wish to address and even prevent some of the signs of aging, without expensive surgeries that require long recovery periods. With that said, patients can expect little or no downtime or recovery period after their Botox treatment, other than some tenderness at the injection site. Some patients experience mild bruising after botox. The bruising can appear right away, or within 1 or 2 days after the procedure, and will typically last from two days up to two weeks.
