These are the most common causes for the development of cornea.
At this page we have already learned what corneas actually are. And in the basics, how it is created.
But let's take a look at the formation of corneas as we encounter them every day, sometimes consciously, sometimes quite unconsciously.
Who doesn't know the feeling when new press shoes and wiggle and after a while. Swelling in some places, which gradually harden?! Sure, bruises and calluses, you know that. In fact, these are probably the best known forms of cornea formation.
As we have already understood, the corneocytes in the epidermis migrate from the bottom to the top and finally peel off at the surface under normal circumstances. But what if this desquamation is not possible, for example because something else - for example the wall of a shoe - is holding against it most of the time?
External influences prevent a natural process
Well, then. urge more and more Corneocytes from inside the epidermis outwards...and there's a accumulation of corneal layersa thickening. This is where we have the cause of most cases of cornea formation, as it is usually understood.
So if you do not relieve this pressure point, which is only formed because the corneal cells are not able to recoat the affected area, and the process of accumulation continues (for example, because the shoes do not soften and you wear them regularly anyway), then after some time even a cornea can develop here. On the one hand this is nothing more than a core of compressed cornea and on the other hand unfortunately often very painful.
So if you keep in mind that corneas are mostly formed where Pressure and load is prevented by the natural recoating of corneal cells, the connection between cause and development of cornea is much better understood in some places.
Mostly through friction and pressure
Think of the heels, for example, which have to carry an immense load (your body weight). Then you will also understand why heavier people often have greater problems with calluses on their feet than lightweights.
Suddenly you may realize that bruise on fingerwhose cause seemed mysterious until now, may have been caused by the ballpoint pen you regularly and persistently hold in your hand during work.
The truck driver realizes that his Elbows is possibly keratinized because it bumps against the side window with the same one every day while working in the driver's cab.
Ultimately, the time factor is then used accordingly. Because once a process of accumulation of these cells has been set in motion and is not interrupted again, the amount of cornea accumulates over time. In other words, this is also the reason why the formation of corneas is perceived more strongly with increasing age.
In summary, we can state that in most cases, the prevention of the natural exfoliation of the corneocytes, often caused by friction, pressure and stress, almost no matter where in the body the reason for the Formation of dead skin.
