I know a lot of people who used Jiaoli including my sister who live in San Francisco, she have melasma. I was surprised when I saw her last month there was no trace of dark spots in her face. She said she used jiaoli night cream and whitening soap.It's really popular on melasma forums. People have said it almost eliminates melasma. I think someone actually did have the cream tested and it came up positive for mercury. I'm scared of mercury poisoning so I don't know if I should even think about using the cream. The only reason I'm even thinking about it is because it has gotten so many rave reviews and nobody is claiming any negative side effects.
