No supplement has strong evidence for meaningfully reducing long-term tip swelling after rhinoplasty. Thick skin commonly retains edema and scar firmness for 12 to 18 months or longer. Arnica, bromelain, and similar products have inconsistent evidence and may interact with medications or affect bleeding, so use them only if the treating surgeon approves. Diuretics are not an appropriate routine solution. The useful measures are regular follow-up, head elevation early in recovery, avoiding nicotine, limiting excess salt and alcohol, gradual activity, and taping or massage only when specifically instructed. For selected persistent supratip edema or scar tissue, the surgeon may consider a carefully dosed steroid injection, but incorrect use can cause skin thinning or contour problems. Sudden swelling, redness, increasing pain, drainage, or breathing difficulty warrants prompt review.
