I suggest you put white vinegar in boiling water and smoke your hands first. When the water temperature cools down, put your hand in the water and put on olive oil. Don't touch too much, then put on disposable gloves for about half an hour, then take them off and massage them until the olive oil is completely absorbed, and then apply too much hand cream to avoid rubbing the quilt. Just stick to it every night. I used to work in a beauty salon. We used to soak our hands in white vinegar, not too much. Here it is (olive oil must not be practical oil bought in the supermarket. You should use massage olive oil. Good olive oil can be absorbed. Its quality is not good. Saibao or the count can do it. I have used it before, and it can be completely absorbed by the skin)
