My solution would provide instant relief... Don't wash your hands a much!
If your hands are starting to crack and actively bleed to the point of plasters, then maybe just maybe you're washing them too often.
The NHS advise to wash your hands:
-when you get to work or arrive home
-after you blow your nose, cough or sneeze
-before you eat or handle food
Seems the suggestion I provided isn't too far from wrong. Before you eat, yes.
But if you're at home alone, why do you need to wash your hands after you blow your nose, if you know you haven't got corona virus? There is no need.
Can just catch it bin it kill it. A dry environment will kill any disease, which is why a tissue is effective then in the bin.
The reason you don't want corona on the hands is in case you then touch your hands, eyes or mouth.
It's a case of common sense, and if your hands are being washed to the point of cracking, then you are making our hand a possible entry of infection.
Considering only eyes, ears and nose is how you currently get infected, if washing your hands makes you at risk of contacting a virus or infection via the hands then that really is doing more harm than good.
