저는 그냥 계속 하나만 쓰는데 글 보니 바꿔줘야겠어요
I heard somewhere that if you use the same product for a long time, your skin adapts to it and the effectiveness decreases.
I also have a feeling it's true for some reason. The product I'm currently using fits my skin perfectly, but I'm thinking of switching it out.
For those who use the product for a long time, is it okay to just keep using it?
I'm curious how often those of you who change them do so.
