Fake pearl powder contains bleach and heavy metals, which will harm your health.

There are few real pearl powders on the market, especially the cheap ones are shell powders, without exception.

Suzhou old brand Zhenshichang, the price of pearl powder is around 10 yuan 1 g (Taobao is cheaper).

The price of real pearl powder is about the same, as long as it is really more expensive.

Pearl powder for oral use exported by Zhenshichang is more expensive, tens of dollars a gram.

Of course, I haven't seen it. I just heard about it. The price can be consulted.
