What products do you all bring for post-cosmetic treatment care?

Hi everyone, I'm Wen. I'm planning to get a cosmetic procedure in Korea soon and wanted to ask you experienced ladies beforehand—what skincare products did you bring with you after your procedures?

I'm currently debating whether to buy some soothing masks and cooling patches beforehand, or just buy them when I get there? I'm thinking I might need cooling and soothing products for the first few days after the procedure, but I'm not sure which brands or types I should use. Has anyone used silicone scar patches? I've heard they help with recovery, but I don't know if they actually work.

I'd like to hear about your real experiences—do you usually prepare everything yourself in advance, or do you trust the skincare instructions provided by the local clinic? If you prepare it yourself, are there any specific types you would recommend (e.g., ingredients, usage instructions)? Thank you all!
