What home skincare products do people bring when they come to Korea for cosmetic treatments?

Hi everyone! I'm Yating. I recently had a minor treatment in Seoul and am currently recovering. I realized I wasn't very well prepared... I just grabbed a few random things at the convenience store.

I'd like to ask experienced ladies, what home care products do you usually bring back or buy after your cosmetic procedures in Korea? I'm especially looking for soothing or cooling masks, as I've heard they're helpful for post-treatment recovery. Also, do you have any recommendations for silicone scar patches or soothing gels? Is it more convenient to bring them from Taiwan or buy them in Korea?

I kind of regret not doing my research beforehand. If I come back next time, I'd like to be more prepared. Your experiences would be very helpful, thank you!
