Needless to say, Korean cosmetics that must be bought are suitable for Asian skin. You can choose a brand that suits you according to your age. The most popular brands are Snow Show (called Breathing in China) and Hera. Recently, AHC is also very popular. I personally tested it, and it was completely easy to use. I bought a whole set of super sensitive muscles for hydrating, and there was no stimulation. Of course, these are all opinions based on your skin type. Secondly, buy cosmetics. If you can't join the group, you can only go to duty-free shops and try to buy things in shopping malls. The products produced by our own production line are specially sold to Koreans, while those sold in duty-free shops are all sold abroad, and the effective ingredients are completely lower than those sold in shopping malls, which is why the products sold in duty-free shops are cheaper (the products sold abroad are not fakes, but the ingredients are lower). Secondly, don't buy fake cosmetics at the east gate of Myeongdong (real goods are not excluded). If you fly, you can buy it in Lotte Silla online duty-free shop, and you will not have to bother to register at the airport when you return home. There is also a discount of 8-9.5% after employees swipe their cards, so UnionPay is good. It is also said that the discount of visa is actually suitable for UnionPay after exchange rate conversion. Of course, if you don't care about Myeongdong, a place where you have a direct tax refund, if you go to the airport for a tax refund, please put away the clothes at Dongdaemun. Many of them are made in Guangzhou at a low price and then sold back to China at a high price, but if you like the price, you think it is reasonable. Just buy that kind of ginseng chicken soup, fried rice cake, fish cake, fish cake, barbecue fried chicken and banana milk. This is an essential Korean food. Korean fried chicken is divided into several characteristics. Make more by yourself. Some are higher but not expensive. Korean cheese is also very good. You can eat other exotic flavors. Well, it's better to try it in a real foreign country. You don't have to go to a tourist attraction. If you talk too much, you will know where to change money because the exchange rate near the east gate of Myeongdong is high, but don't change too little, it's inappropriate and you don't want to change your portable wifi. Please take it with you and have a nice trip.
