There is another reason why work is different. Some girls' families are better, or their parents love them, so their hands will be white and tender without work. Then some people's family is not very good, and they often run around, so the skin of their hands will become rough and then turn black.
One of the most important reasons is that girls naturally love beauty, and they also like to use various cosmetics to maintain their skin. The face and hands are the most important places, so the hands are particularly delicate and smooth.
If girls want to make their hands white and tender, they should also develop good living habits, starting with diet. For example, carrots, tomatoes, cabbages, onions and other vegetables contain a variety of trace elements, which can moisturize the skin and beauty beauty. And drink more milk, milk is rich in minerals and various nutrients, so drinking milk for a long time is very effective for beauty beauty.
