Second, exercise. Koreans like sports, mountain climbing, going to the gym to exercise, and cycling around the community on weekends. They don't just chat with relatives and friends on weekends. As long as the weather is fine, they will exercise together to relax themselves. Because of this, their mood is relaxed and their skin will naturally improve. Even if they meet and drink after exercise, isn't moderate drinking better for their health?
Third, drink milk. Koreans, old and young, like to drink milk. They drink milk every day in kindergarten and free in primary school. The school will provide the corresponding milk.
Fourth, there will be no excessive pressure. Koreans will not forget their physical endurance for work, but will do their work well within their endurance. They won't get carried away like the Japanese, and spend all their time at work, ignoring the importance of health.
Fifth, plastic surgery. South Korea's micro-plastic surgery, dermatology, skin care products and cosmetics industries are very developed. Use super good skin care products every day, see a doctor when you have acne, and do micro-plastic surgery since childhood. Of course, your skin is very good!
