I haven't heard of it. There are too many things to remove spots now. To tell the truth, it's a trick, but it's of little use. I used too much before. I had spots when I was a child, and I didn't spend less money at that time. It's just the combination of Meitai Sakura that my husband and elder sister told me the year before last, and those annoying spots are gone. That one is surprisingly good, and the spot is much better than the skin.
