What skincare products did everyone bring for the post-beauty trip?

Hi everyone! I recently had a minor treatment in Korea and am currently in the recovery period. I've realized I lack experience! I'm wondering what skincare products those of you who frequently come for beauty treatments usually bring with you? Like cooling masks or silicone scar patches?

I'm starting to regret not preparing more in advance. I've heard some people bring their own soothing gels and cooling products, which are more convenient during recovery and save them from having to go out to buy them every time. But I'm not sure which items are most practical, or if it's more convenient to buy them locally in Korea.

Any ladies out there who can share their experiences? Do you usually bring your own skincare products from China, or do you buy them in Korea? I'd especially like to know everyone's opinions on cooling and soothing products!
