Skincare or Makeup? Korean products wise, everyone should get Nature Republic's 92% Aloe gel, it comes in a tub and its a great multipurpose product. Snail creams are very popular, if you are into skincare. Mizon has a good one. Tony Moly and Etude House are good cosmetics brands to check out, cutesy packaging. Lip tints are super popular in Korea, you can find them at Tony Moly, Etude House, Clio, Holika Holika, the Face Shop, pretty much everywhere. Clio Lipnicures are very popular, if you like liquid to matte lipsticks. Aritaum has great tinted lip balms that are super popular. BB cushions are super popular, they give a nice natural looking finish. They also have a lot of beneficial ingredients. Popular ones are from the brands Laneige, Hera, Innisfree and pretty much any of the other brands. If you are into skincare, korean facial sunscreens are the best ever. Very lightweight and nourishing. Nature Republic and the Face Shop has really good ones. I have combo oily skin and I have the Sebum control moisture sun from the face shop and nature republic California aloe sun 35 spf. Excellent products. The face shop has a good selection of those, if you don't have oily skin and the nature republic one isn't specifically for oily skin. As for Japan, not too sure. I heard their Cure peeling gel is amazing and have not tried it. The only makeup brand I know of is Canmake, so maybe that is worth checking out. I hope this helps!
