That’s a very thoughtful question, and I completely understand your concern. Bruising after fillers can be frustrating, especially if it happens every time. Having low iron doesn’t directly cause more bruising, and taking iron supplements just a few days before your filler treatment, unfortunately, won’t make a noticeable difference in reducing bruising. Iron works more on red blood cell health and oxygen transport, rather than on blood vessel fragility or bruising risk. What tends to help more is avoiding certain blood-thinning medications or supplements (like aspirin, ibuprofen, fish oil, or vitamin E) for about a week before your procedure, if it’s safe for you to do so. Applying a cold compress immediately after treatment and using topical arnica or bromelain can also help reduce bruising and speed recovery. Since you know you bruise easily, it’s good to let your injector know ahead of time so they can use techniques to minimize trauma, such as using a cannula in certain areas.
