Is that the detoxification capsule on Taobao that was tested on the street for free? Street skin test, white ointment applied to the face, with a metal probe, will immediately appear black.
I don't know if it's the same thing. This kind of thing on Taobao should be illegal and should be severely punished if it is caught by Taobao.
It's not even magic to blacken the ointment. It's just a simple chemical reaction. Just find your own way.
The "detoxification" of such items on Taobao is illegal. It depends on whether Taobao strictly examines and punishes.
Have a nice day!
