Even tho the cream works very well, it doens't mean in long term its not harmful for your skin becuase its made in China !
Even the china government itself is so "dark", how can you trust the QC in China? There's nothing you can trust about China ! If you check the internet, nowadays people from a lot of countries are avoiding products from China.
If you have friends from US, I think its better to ask your friend to send you this cream if you really want to try it. At least its made in US.
