When clients get an injectable treatment such as dermal fillers we provide them with a package of Arnica, a homeopathic pill that dissolves under the tongue to reduce bruising. We recommend they take the Arnica immediately after the treatment and over the course of the next few days. We also recommend the use of a topical Arnica gel that can be purchased over-the-counter at most health food stores or pharmacies. A Multiwave LED treatment can also help to resolve to bruise more quickly. The bruising can usually be covered with make-up. Typically bruising lasts about one to five days. Some patients do not have any bruising.
