After minor surgery, how should I prepare for swelling reduction and care products for international travel?

Hello everyone, I'm Qing. I've been considering a minor aesthetic procedure recently, but I have an international trip planned shortly after the surgery, and I'm a bit worried about swelling and recovery. I'd like to ask friends with experience for advice on the best approach in this situation.

I'm particularly interested in how to effectively manage swelling post-procedure. Besides ice packs and elevating the treated area, are there any other techniques? Also, since luggage space is limited for my trip, are there any essential skincare products or tools I should bring? I'm concerned about carrying too many items.

I'd also like to ask, how far in advance do you typically undergo such procedures to feel comfortable traveling afterward? Are there any specific precautions to take during the recovery period? For example, regarding diet, exercise, or daily skincare routines? I would be incredibly grateful if anyone has gone through a similar situation! I want to be well-prepared.
