Japanese beauty, or J beauty, is ideologically very similar to Korean beauty, they both focus on prevention more than repairing damage afterwards. The Japanese skin care routine is not much different from the Korean version either.
Cleansing (the Japanese also prefer double cleansing).
Moisturizing (toner, essence).
Strength - prevention of skin problems by choosing the right products, for example adding anti-aging products to the routine (serum).
Renew the skin with an appropriate product according to what it needs, such as choosing a product to even out skin tone, fade wrinkles and so on (moisturizer).
