We'll pay you ten thousand American dollars if you find us a good quality Chinese dermaneedling machine. We're the largest Dermaneedling company in the world and in over ten years in this business, with access to everything made on the market, we saw ourselves forced to develop our own machine because we can't take the risk of getting sued by our customers. Contact us via our support ticketing system when you can send us such a device that does not tear up paper as we showed in this video. Dermaneedling works by repeatedly, over the course of months or years with multi-week intervals injuring the skin by creating vertical channels into it of therapeutic depth, triggering collagen and elastic regeneration in a smoother matrix than the scar tissue it partially replaces. Tearing the skin (and the edge of pores...) apart horizontally, which we call microtearing, is a bad thing. Our machine is the only machine that does not cause microtearing. We tried many machines, we have much worse machines in our posession than the one we showed here. A Korean machine, the mCure, was actually the worst, downright criminal to sell. I'm not kidding about that $10,000. Ten thousand dollars to learn of a resellable Chinese machine would be extremely valuable to us, then we can double our assortment! AFAIK they do not exist. And ALL machines (except the mCure and our own machine, the Derminator...) are made in China, whatever the seller claims. Our machine is the only machine made in Europe (by ourselves, even I am part of the production, I do the calibration) and the only machine made by a Western (= sueable when it destroys your skin!) company.

+mattinuk The high speed is used primarily to be able to show very clearly the tearing effect. The tearing we showed is at least a full mm. It should be zero mm. How much tearing is acceptable? 0.25 mm? That means that even a speed that is four times less would cause unacceptable tearing. The limit of acceptable tearing depends on the susceptibility of the skin, which mainly depends on the age of the skin. Secondly, when needling devices are used without power cord (battery operation) they tear *much* worse (two to three times worse, depending on charge status). So worst-case (older patient, battery operation), even using a twelve times slower speed would result in unacceptable tearing. On top of that, we used our own cartirdge on the competing device. Their original cartridge tears so badly that it even causes tearing on our machine! The video is just to show that the phenomenon of microtearing exists (several competitors claimed we made the entire phenomenon up) and that our machine does not suffer from it. Which speeds are risky depend on many factors, such as how bad the machine is (there are MUCH worse machines than the YYR Dermapen, such as the Korean mCure!), the skin's age and how powerful the machine is when used with a battery (which discharges during use, tearing will be worse near the end of a 15-minute treatment, especially with an older battery). In addition, some skin practitioners really do move electric needling devices too fast, just to save time. I've seen speeds that made me cringe.

+TheMsDudettes There must be a misunderstanding. Never did we say that the dermaneedling instruments we sell should not be trusted, neither did we ever say that cheap manual dermaneedling instruments in general should not be trusted. On the contrary, when you audit the available instruments there are certain manufacturers that produce high quality instruments. We work with such manufacturers, and it took us years to find the very best (there are only two manufacturers in the world that produce good needle quality consistently, and our rollers are copied by Chinese manufacturers). As with all products, there also exist manufacturers that use needles with the occasional bent tip or who sell rollers with stamped "knives" instead of real needles (the ones with 540 "needles") The reasons for buying a Derminator have nothing to do with the quality of dermarollers and dermastamps. The reasons for buying a Derminator machine are as described on our sales page and in our store: Consistency of needling depth, guarantee of correct desired needling depth, order of magnitude less pain compared to manual needling, machine knows how long to needle a certain selected area size, no microtearing (all electric machines except ours cause microtearing), ease and speed of use (esp. for smaller areas such as the face), option of having a single needle, etc. etc., really too many advantages to list all here..
