How much hand cream should I apply?

If you wash your hands often, you will naturally get it right.

Some days, a little is enough, but on other days...

Even though I apply enough to make my hands slippery, they feel dry quickly. I understand that you are supposed to apply it differently depending on the situation, but sometimes it gets on the objects I touch too much and feels slippery, so I should adjust the amount and apply it frequently.

It seemed to help... How much is usually appropriate to apply?
