나도주라
쓰면 좋겠지만 피부도 과하면 좋지 않다해서 가끔 에센스만 쓰고 있어요. 세럼은 잘 모르겠네요.
I am wondering if I absolutely have to use both an essence and a serum. I am told to apply either an essence or a serum after the skin toner, but I am not sure if it is better to use both or if using just one is sufficient.
Some people say it is better to use the essence and serum together, while others say you don't necessarily need to use both.
I am wondering if it depends on skin condition, or if using just one is sufficient.
I would appreciate it if you could also tell me the criteria for choosing essences or serums, as well as the order of use.
