Electrical hard skin remover
An electric cornea remover is the latest trend in corneal removal and is flooding the market right now. And as always, many people are impressed by the concentrated power of advertising.
This refers to an electric cornea remover. This fabulous invention, which for some time now has given us the impression of having completely reinvented the wheel
Fact is: The only new thing about these devices is the design. Every device that starts to remove cornea by electrically rotating a rough surface is an "electric cornea remover". And such devices have actually been around for a long time. In the new generations a roller turns, in the old ones usually a cone or a disc. Now some manufacturers advertise the graters, which are offered in understandable, different colours for the different grit sizes, as novel microgranulates, but they omit a detailed explanation of what advantage a microgranulate would have over an ordinary sandpaper or file. But what effects rubbing or sanding with similar pedicure equipment can basically have is described by Mr. Fuss on this linked page. To be precise, an electric cornea remover of the current generation is just what has been around for a long time:
A sander for corneal ablation, this time with the handle shape of an electric razor and a transversely running sanding roller with 30 revolutions per second. Don't be blinded by marketing sleeves. Just like the detergent, which for the last 100 years has brought a new formula almost every 6 months to make your washing even whiter, so do the electric cornea removers. Maybe you still remember the corneal egg? Only a few years ago it was a much praised further "newest achievement" of the cornea removal technique. Basically, it was also nothing more than a grater, packed in the shape of an egg. The only new feature was the collection container for the grated cornea, which was connected to the mould. The disadvantages of grinding, on the other hand, were naturally the same and today no rooster crows after it anymore.
Conclusion: A new dress does not make a new technology. A lot of wind around old things and no reason for hysteria. Better look for a real alternative. An electric cornea remover probably doesn't offer you much new, but grinds just like countless other foot care appliances. However, sanding is often the cause of rough skin and therefore does rather the opposite of what you want.
