Exactly. What people don't understand is that economic interests are not fundamentally opposed to the progress of technology--they actually drive it. We like to think that technology soars as high as our aspirations, but invention costs money and at the end of the day, commercialism pays the bills. We are constantly promised flying cars and cities on the moon, but the real tangible products only arrive when they become economically viable in some sense. There were mp3 players before the iPod, but only the iPod really pushed the market forward such that technological innovation went from better and better mp3 players, to smart phones, to tablets, etc. This is because, on the one hand, the iPod was surrounded by excellent marketing, and on the other hand, the product itself was shaped by economic interests to target the then-current market in a superior way. Hence it may not be that the iPod was the best and newest technology that could be produced, but it was perhaps the best blend of innovation, marketing, and economic viability for the situation, and thus because of its marketability it drove future innovation in the direction of handheld wireless devices.
Back to the situation at hand, companies that sell skincare products do have a vested interest in bad skin, but only to the extent to which it enhances the marketability of their products. They might be able to form a conspiracy network and hide such a miracle product only if human nature were not what it is, and economics were not driven by competition. One company still has to compete with another, and so one company will likely invest in high-tech means of skin care in order to dwarf another. Thus there will be no conspiracy to bury this new technology. Rather, one company will promote the technology enough to gain an upper hand in a high-end market (e.g. not cheap Suave products like I buy), but cost and convenience will prevent this technology from eliminating the skin care industry altogether.
Human genetic engineering could change the situation, but that will involve complex issues (patented genes?) and other economic and political factors that will be external to the skin care industry in itself. Like all other technologies, human genetic engineering will be driven by the economy, no matter how much transhumanist idealism pushes for it as the supposed next step in human evolution. In the meantime, this particular discovery will more likely lead to lesser technologies that purport to target Granzyme B without eliminating it genetically.
