The evidence is mixed and limited. Arnica and bromelain are commonly recommended after cosmetic surgery because some small studies suggest they may modestly reduce bruising or swelling, especially in facial procedures, but the data are not strong enough to call them essential or clearly proven for tummy tuck recovery. For abdominoplasty, recovery usually depends more on careful surgical technique, compression when recommended, walking to reduce clot risk, good nutrition, avoiding nicotine, and following your surgeon's activity and wound-care instructions. Supplements should be viewed as optional supportive measures, not as a substitute for those basics. It is also important to ask your surgeon before taking them. Bromelain can interact with some medications and may increase bleeding risk in certain patients, and arnica can cause reactions in some people. If your surgeon approves them, they are generally used as an add-on rather than a core part of recovery.
