With any injection, there is a risk of bruising, swelling or pinpoint bleeding. These side effects are temporary and typically subside within hours or days after your injectable session. We will work with you to reduce your risk of side effects, including icing your treatment areas to curb swelling. We also recommend that you avoid blood-thinning substances, such as vitamin E supplements, alcohol, and NSAIDS, at least a week before and after your session to reduce your risk of bruising.
