I advise you not to believe it either.

First of all, beauty salons are not qualified to buy medicines at all, which is illegal sales in itself.

Second, what they call "medicine" is not necessarily what it is. There is nothing wrong with spending money inefficiently. If there are any side effects, it will be troublesome. In case something goes wrong, once the door is closed and people leave, there is no place to complain.

Third, think back, if there is this magic medicine, will there be so many people trapped in the disease? Whoever invented this magical medicine must have won the Nobel Prize in Medicine long ago.
