[Product Request] Going to Japan and Korea soon and need skincare advise

Hello everyone!

I will soon be in Korea and Japan and wanna buy skincare. First of all: Which country's skincare do you prefer and why?

I have dry skin and turn 26 soon. Normally I don't have problems with pimples. Wanna use more skincare to prevent my skin to get wrinkly too soon. Atm I just use a Nivea face cream and an eye serum cream.

Thanks a lot :)
