This has probably happened to a lot of you because of taking notes in class.
Have you ever got a little blister or callus because of composição literária too much on your finger? It's normal. All it is is a small callus from the pen applying a bit too much pressure or rubbing for too long against your skin.
Calluses are not dangerous, but they aren't pretty either. All people who practice something with their hands all the time get them. Playing the violão, guitarra or even cooking a lot can result in calluses.
So you have some calluses and you want to get rid of them. Fine. Use pens that have a little padding and try not to push down so hard on the pen.
You can also do a treatment to get rid of calluses. Put your hands in warm water with limão for 10 minutos and let them soak. Then dry them off and apply creams or amêndoa oil to the callus. Use hand cream daily and you will see a difference.
If the callus hurts and does not go away then ask your parents about it. Lol
