To some extent some bruising is inevitable but here are some things:
Avoid medications or supplements that can promote bleeding
Use local anesthetics with epinephrine that reduce bleeding
Maintain low blood pressure during and after surgery
Keep head elevated after surgery
Use ice packs to forehead and temples after surgery
Avoid bending and lifting after surgery
Regardless of the operation, pre-operatively I give patients a list of medicines, vitamins, and foods to avoid because they can thin the blood and interfer with natural control of normal intra-operative bleeding. I do have patients take Vitamin C, Arnica, and a Medrol Dose Pack. Having said that, follow your surgeon's instructions.
What Can Be Done to Minimize Bruising After a Brow Lift?
I have found a medrol dose pack and Arrnica 12-C oral as well as Arnica Gel to be the best at limiting post Brow Lift (and all plastic and cosmetic surgery procedures) swelling and bruising. You should ask your Brow Lift surgeon for specific recommendations.
