I have heard a saying that South Korea began to use some functional skin care products at the age of nine. It's incredible. After all, I am nine years old and still a child. Won't it hurt your face to start using these skin care products at such a young age? In fact, as far as South Korea is concerned, skin care products are usually used for them when they are still in primary school. And the types used are mostly moisturizing and hydrating. It is also for this reason that many Koreans are still tender in their thirties and forties.

Skin care products that have been opened for more than a year should be thrown away. As far as many people in China are concerned, everyone is adhering to a frugal habit and tradition, so as long as the food doesn't look bad, there is no hurry to throw it away. Koreans, as long as they use skin care products that have been opened for one year, most of them will throw them away. After all, at this time, almost all the good ingredients evaporated.

Drink more water. 90% of the human body is made up of water. Therefore, drinking water itself is not only helpful to all aspects of our body organs. Drinking more water will also make our skin smoother and more delicate. In Korea, many people have the habit of taking mineral water when they go out, and students even have to take 1.5 liter of water to school.

In the eyes of Koreans, if you can drink two bottles 1.5 liters of mineral water a day, your skin will be as good as changing your skin after one month.
