The next step was to send the products to an authoritative institution for testing, and the results were within the expected range.
With the exception of Beauty & Home and the other no-name product, all other brands had tested products and over-the-counter purchased products that very much met the usage standards, and the various indicators did not significantly differ from what was stated in the manual.
However, the effective isolation ingredients contained in Beauty & Home's primer differed greatly from what was described in the manual. It didn't even reach 50% of the claimed value...
As for the heavy metal content, the values were frighteningly high. This wasn't an isolation cream; it was a disfigurement cream!
But the product that Beauty & Home sent directly met all the standard values, a product that couldn't be more qualified.
