The first one is "mask". There was definitely no patch mask in ancient times, but there was a mud mask, such as grinding pearls into powder to make a pearl powder mask. We are still using this method. My mother went to the Chinese medicine shop to buy pearl powder and take it home with diy mask.
Now there is another mask, Qizibai. I can't tell which one is qizibai. Anyway, it's seven Chinese herbal medicines. Qizibai mask can whiten skin.
Ancient Europeans also advocated white, because at that time, white skin meant that your family was rich, because white skin meant that you didn't often bask in the sun, and people from poor families needed to go out to work, so they got a tan. Therefore, in order to make their skin whiter and whiter, women at that time would use something containing mercury to whiten it. The whitening degree can refer to Charlotte in English drama.
Compared with the whitening methods in Europe, the whitening methods in ancient China are still very safe.
