Not all necessities in shopping malls are genuine. Must-have apps are controversial. Some say it is genuine, some say it is fake, and some say it is a mixed bag. In fact, the direct selling suppliers in the Necessary app are real, and they are probably the big-name cosmetics or products they make. There is no doubt about this. However, the same supplier, produced in the same workshop, has different products, different formulas, different raw material procurement, different production processes and packaging material procurement standards. So there are still some doubts. It may be a gimmick for direct supply from big-name production suppliers. Must-have items in the mall are worth buying. In fact, it’s okay, not a loss. Some products are even surprises, especially skin care products, electronic products, and daily necessities. It just doesn’t want to be too good, so now except for unnecessary items, I buy everything else on the platform.
